Abstract
Many agencies today still use outdated paper maps and construction plans to manage their utility
systems. Those using outdated information and methods can benefit from a digital upgrade.
Geographic Information System (GIS) is becoming a common solution for asset management
and utilities because of its ability to combine spatial and non-spatial information all in one place.
This project implements a GIS for the landscape irrigation system on the Music Academy of the
West campus in Montecito, California. Campus staff were using a series of disorganized and
incomplete paper maps to manage their irrigation system. They also had no information about
where the main line and lateral lines were, which proved to be problematic during construction
projects and pipe leaks. Transitioning the paper maps to digital GIS format proved to be a good
solution. Using GIS, spatial data collection methods, campus staff knowledge, and existing
construction documents, new hardcopy maps and an online web map application for irrigation
management were developed for campus staff. In the future, the new irrigation map data can
provide efficient solutions for future campus facility projects such as water usage analysis and
leak detection device placement. Creation of GIS data for irrigation and other utility systems will
likely continue to be a solution for effective asset management in the future.

Chapter 1 Introduction
This project is a case study for the Music Academy of the West (MAW), a small music
conservatory in Montecito, California. On the southeastern coastline of Santa Barbara County are
approximately nine acres that make up the campus – a compact area with plenty of plants to
water. With only outdated documents to reference, campus staff expressed a need for updated
maps of their system.
The campus itself is over 100 years old, and various undocumented pipelines have been
found underground. MAW staff have a need to distinguish between their active system
infrastructure and old abandoned infrastructure. Updating maps will help prevent workers in
ongoing construction projects from hitting unmarked underground irrigation pipelines.
Additionally, they have had water leaks in the past and did not have the resources to quickly
know which valve to use to turn off the water to a specific area. They were also aware that their
controller maps for their irrigation zones were inaccurate and incomplete, making it difficult to
know how to water specific areas. Their goal was to have updated maps to use to manage their
system more effectively. The location and extent of the campus is shown in Figure 1.

1.1. Overview of GIS and Utilities
Mapping and asset tracking are important when it comes to utility systems. Agencies that
have been using outdated map atlases and mapping methods are now commonly turning to GIS
as a solution. For many utility systems worldwide, GIS is in the planning or implementation
stages (Cannistra 1999). For example, East Central Energy, a cooperative for electric utilities in
Minnesota and Wisconsin, recently completed a massive GIS inventory for all their system
assets. Team members were sent out to collect over 200,000 data points relevant to their system.
In the end, the GIS inventory “improved accounting management, knowledge of underground
assets for underground utility location requests,” and improved maintenance by providing system
age and location information (Wick 2009, 22).
GIS is an appropriate tool for infrastructure management because it combines a visual
map component with a database component. Unlike using scattered paper documents from
varying sources, users can easily compare spatial relationships and details of features all in one
place (Johnson and Goldman 1990). Common utilities that use GIS include gas, electric, sewer,
and water. Water service districts and irrigation systems are two common types of water utilities.
For this project, landscape irrigation refers to the systems installed for the automatic distribution
of water to outdoor landscaping, for instance, a garden or lawn in a park.
1.2. Motivation
With the speedy advancement of electronics and software, it is important to research the
process of converting system maps from paper to digital. After a construction project is done,
contractors must provide finalized documents showing what changes were made and how the
utility assets were built or altered. These final documents are called as-builts. As-builts are
generally more detailed and more legible when they pertain to newer systems that were installed
4
more recently. However, they are not always completely accurate, regardless of the date they
were created. Furthermore, with older systems, the documentation may be even less revealing.
Maps can still be created despite a lack of information. Figure 2 shows an example of a
paper map that MAW staff were using prior to this project. It is a cropped selection taken from a
construction plan that was annotated by hand. This proved to be only a temporary solution for
them. The maps had not been updated when construction work was done and there were also
errors in the original annotations. It is more efficient to have the data stored digitally so that
updates can be made, and new maps can be more easily printed or viewed after changes are made
to the system. Appendix A contains additional figures of all the old paper maps like Figure 2 that
are not included in the body of this paper.

Reger (2017) studied this conversion process, referencing numerous factors affecting the
mapping of a system using any existing information available, in some cases resorting to
knowledgeable staff and basemap data when documentation was limited. This digital conversion
will likely continue to be relevant in the field of GIS for some time until it becomes common
practice to create GIS data concurrently with the installation of a system. Thus, it is an important
topic in the GIS field to assist those still using outdated hardcopies.
The results of this project and similar projects may help promote the more efficient use of
water. It is common for irrigation water to account for between 30% and 66% of water use in a
community (Salvador et al. 2011). The state of California is constantly reminded of drought
conditions and water-use restrictions. Climatologists say dry conditions will continue to be
aggravated by climate change. To cope with this, there are many initiatives to evaluate the
efficiency of watering systems (Rundle 2009). To evaluate an irrigation system, it is first
necessary to be aware of the system layout and all relevant assets. GIS offers a solution to this
task, as it allows for the storage of both spatial and tabular information. GIS can then provide the
necessary tools for further efficiency evaluations, such as identifying locations to place leak
detection devices. Additionally, identifying and mapping all irrigated zones on a campus can
serve as the first step to further analysis. For instance, GIS maps and data can be used to compare
water usage to actual water requirements for each irrigation zone.
1.3. Project Objectives
The goal of this project is to conduct a complete field inventory of the MAW campus
irrigation system and create up-to-date maps for campus staff to use. MAW staff initially
requested updated paper maps, however, a web map application will also be created. Although
they did not ask for a web solution, it will be provided to them as an option because it will
7
showcase modern web GIS capabilities. MAW staff do not have experience or sophisticated
knowledge of GIS, so it is possible they will eventually prefer an easy-to-use web solution over a
static paper map system. Providing this web map as an option could also open the door for
additional GIS work with the campus.
1.4. Thesis Organization
The remainder of this thesis document is divided into four chapters. Chapter 2 includes a
literature review of related studies and concepts. Chapter 3 outlines the methodology and how
the workflow was divided into various stages. The results of the project are presented and
discussed in Chapter 4. Lastly, Chapter 5 discusses the project conclusions, challenges
encountered, and future work.

Chapter 2 Background
In order to conduct such a project for the MAW campus, it was necessary to become familiar
with similar projects that have already been completed. It was also important to research
concepts that would be encountered during the project, including asset management, elements of
successful cartography, and web GIS. Lastly, it required an understanding of the underlying
landscape irrigation system structures and functions.
To address these elements, this chapter is organized into four sections. Section 2.1 covers
GIS and Asset Management, beginning with a simple definition of asset management and a
further description of the relevance of GIS for asset management. Section 2.2 covers GIS Project
Management, including some recommended best practices and a review of past research done for
small water systems. Section 2.3 covers Cartography and Web GIS, including guidelines for
creating maps and an assessment of various web GIS options. Lastly, a brief overview of the
functions and structures involved in landscape irrigation systems is covered in Section 2.4.
2.1. GIS and Asset Management
The purpose of an asset management system is
to help you know exactly what assets you have, know precisely where your assets are
located, know the condition of your assets at any given time, understand the design
criteria of your assets and how they are properly operated and under what conditions,
develop an asset care (maintenance) program…, and perform all these activities to
optimize the costs of operating your assets and extend their useful life to what was called
for by the initial design and installation (Davis 2007, 26).
GIS is becoming more and more prevalent in asset management. Miner (2005) surveyed
utilities and governments to create the Geospatial Technology Report, which serves as a
benchmark for utilities to compare their GIS projects and usages with other utilities around the
world. The report included responses from 43 different utilities and governments, primarily from
9

the United States. GIS database maintenance and work management were the top geospatial
applications in the water, wastewater, and stormwater industry in 2004. The top geospatial
technologies included GIS software, GPS, and document management (Miner 2005).
Using GIS to track spatial and tabular information over a variety of different thematic
layers can reveal trends that may have otherwise remained hidden in spreadsheets or other
documents. This supports more informed decision-making and the potential for the more
efficient management of utility systems (Hanson 2008). GIS serves as one common tool, able to
consolidate a variety of information from many incongruent sources. This contributes to its
capabilities as a communication tool, since many people find it easier to understand information
when it is presented as a visual map (Shamsi 2005).
For example, Makar (2017) conducted a study combining GIS with an existing asset
management system for fire hydrants in Buffalo, New York. Buffalo Water struggled with aging
and damaged infrastructure, particularly pipelines and fire hydrants. GIS was used to study
trends in hydrant damage, and to predict where hydrants were more susceptible to damage from
weather or vehicles. These conclusions could be used by Buffalo Water staff to make informed
decisions about hydrant maintenance. For example, they could predict which hydrants needed to
be relocated and which areas of the city would require the most attention.
A similar project was carried out by Ismanto and Mustofa (2015) for the Public Works
Department of Merauke Regency in Indonesia. The department was able to develop an
interactive map tool that provided all the necessary capability to access, manage, and update the
information for their system of irrigation canals. They concluded that using a map as an interface
was an easier and more efficient solution for making decisions. For example, it was reported that
10

the new GIS tools made it possible to plan for maintenance as well as monitor resource potential
within the system.
2.2. GIS Project Management
2.2.1. Best Practices for Converting Utility Data to GIS
Cannistra (1999) provides a general overview of the necessary steps to take and
considerations to be made when converting utility data for a GIS and emphasizes the need for
structure when it comes to planning such a conversion project. In the early stages of the
conversion process, “a base map must be developed” to be used as reference and help define
what scale the database will use (Cannistra 1999, 59). There are different options for the method
of data conversion itself including: dimensional entry using offset distances from as-builts to
base map features, scanning of documents and conversion from raster to vector, capture of
features through scanning or heads-up digitizing then readjusting locations to match the base
map, and field inventory. Most of these methods are not perfect. For example, scanned
documents can be used to create vector features, but it can be difficult to accurately acquire the
information without manual review, especially when it comes to reading labels to input attributes
and addressing topology issues. Additional issues can arise when as-built documents are
outdated or otherwise inaccurate (Cannistra 1999).
Thus, a combination of the methods listed by Cannistra (1999) seem to be a potential
solution. It seems that most as-built documents are not entirely accurate representations of what
is in the field. This could be a result of the installation crew deciding to slightly modify the
configuration or a subsequent project modifying a configuration after the fact. Therefore, a
method using only scanned documents to either digitize or convert from raster to vector would
not necessarily output a dataset accurately representing the real-world system. A combination of
11

scanned documents and field inventory, however, would use the valuable information from the
as-builts while verifying each asset in the field along the way.
When conducting a GIS project, it is important to address the needs of the intended end-
users of the data and other final outputs. Crawford (2012) implemented GIS for three utility
departments in Calhoun, Georgia. This study was highly focused around the idea of completing
user needs assessments for each department. Crawford (2012) used concepts mentioned by
Shamsi (2005) and Cannistra (1999) to structure a basic needs assessment checklist, which
includes staff interviews to identify current workflows, overall goals, existing data, and potential
applications. The result of the needs assessment was a list of major functions and processes to be
addressed in the GIS implementation, as requested by the users.
Asset inventory should be done in the early stages of a utility project because it allows for
an initial understanding of the current state of the system. It identifies and documents gaps in the
system and its data, which can then be dealt with in a more targeted manner (Heltzel 2003).
Conducting a project like this will likely “take many years but the proper approach will provide
increased benefits from each task required to complete the system” (Heltzel 2003, 27).
After the final GIS products are created, it can be valuable to allow users to provide
feedback and ideas for future improvements. Grotefend (2017) demonstrated a process for
evaluating a web map application after it was completed and made available to the intended
users. A web map application was created for airport staff to interact with pavement condition
report data. Airport staff who were not involved in the development of the application were
chosen to evaluate the final product. These users were sent a link to the survey form through
email and given ten days to respond. The survey form was created using SurveyMonkey, which
allows for the rating of statements on a five-point scale as well as answering prompts with
12

freeform text responses. This proved to be an effective way to receive feedback on the final GIS
product.
2.2.2. GIS for Small Water Districts
Reger (2017) conducted a similar project implementing GIS for a small community water
district. The needs assessment was much simpler, involving a meeting with the water district
staff to conclude what the project would entail. A simple assessment of the existing data and
desired result is all that is needed since it is a small campus still in the early stages of its GIS
journey. Early meetings with the Music Academy staff revealed the need for a simple and
updated map, which required a complete field inventory. After the initial inventory and data
creation process, the user may have additional needs and another assessment may be needed in
the future.
Reger (2017) used a few different sources to create the final GIS data. An evaluation of
existing sources concluded that the district had old computer-aided design (CAD) maps and as-
builts. This information was used to create a summary of the features that would need to be
collected in the field using a GPS unit. After the field data was collected, it was used in
combination with the CAD maps, as-builts, and staff knowledge to create and edit the final GIS
data. This study is comparable to this project in that it involves mapping a utility using limited
and outdated information. The methods are similar for implementing GIS for the MAW campus,
as there are only outdated as-builts and hand-drawn maps as source data. This project differs
from the study done by Reger (2017) because it involves a different utility and goes beyond the
creation of hard copy maps to create a web map application to allow the users to access and
interact with the new data.
13

2.2.3. Irrigation: GIS at the Campus Level
Both Reger (2017) and Gosh (2016) reinforce the importance of referring to staff for help
where existing sources are limited or non-existent. Gosch (2016) conducted a case study
implementing a landscape irrigation GIS for the Veteran Affairs campus in Palo Alto, CA. This
study used staff knowledge as a principal source for creating the GIS data, unlike many of the
key methods used and recommended by Cannistra (1999), Craword (2012), Shamsi (2005), and
Reger (2017). Gosch (2016) used several meetings with the campus’s landscape architect, who
sketched details of the system by hand, which were then used as a reference to directly digitize
features into ArcMap. Because of the helpful and knowledgeable staff members, Gosch (2016)
created the data without field GPS collection or as-built digitization.
Gosch (2016) successfully mapped all irrigation zones, controllers, and valves for the
Veteran Affairs campus. It was mentioned that an item for future work would be the inclusion of
the underground pipelines into the GIS. The initial plans for the MAW project included the
mapping of the pipe main lines and lateral lines along with the irrigation zones, controllers, and
valves. It also reinforced the importance of working with staff members to ensure all available
knowledge is considered when creating the GIS data. A combination of existing available source
data and staff knowledge seemed to be the most reasonable approach for the MAW project.
2.3. Cartography and Web GIS
2.3.1. Map Creation
Creating maps requires an understanding of map elements and how to manipulate them.
There are three basic map components: scale, projection, and map symbols. Scale and projection
for this project are addressed in Section 3.3.1. “Map symbols can differ in size, shape, graytone
value, texture, orientation, and hue” (Monmonier 1996, 19-20). Shape, texture, and hue are the
14

best properties to manipulate when displaying qualitative differences. To display quantitative
differences, varying symbol size or graytone value is best (Monmonier 1996). It is also important
to consider the purpose and intended users of the map. Careless manipulation of map elements
can produce a map that is difficult to understand or use. These concepts were considered when
final symbols were chosen for the map legend in both the new controller maps and the web map
application.
2.3.2. Web GIS
With the increasing use of web-based applications, GIS is no longer restricted to
professionals. This leads to the need to improve user experience, which refers to “the level of
satisfaction a person gets from using a product or service” (Fu and Sun 2011, 45). GIS can now
be used by non-professionals who “have no concept of GIS except that they expect it to be as
easy to use as a regular Web page and as fun to use as a multimedia center” (Fu and Sun 2011,
45). Thus, web applications should be “fast, easy, and fun to use” (Fu and Sun 2011, 45).
Because of the importance of user experience, the workflow for this project included user
training and feedback regarding the final map products.
Mobile web GIS is becoming more common in utility management. Traditionally, field
inspections are done using paper notes and entered into a database at a later time. This method of
updating information can be inefficient and filled with mistakes. Mobile GIS can allow users
access to the data while in the field, making it easy to see assets and update them simultaneously
(Shadin and Tahar 2015). To get to the point where a utility system can be managed in this way,
it is first necessary to conduct projects that create all the GIS data and publish it on a web map
application.
15

2.3.2.1. Google Maps API
There are several options when it comes to creating web map applications. One option
involves using the Google Maps API, which provides a variety of customization capability. For
example, one can use Google’s geocoding service, animate map items, create interactive
annotations, and more. Markers can be placed on points of interest, and InfoWindow Objects can
function as map tips. Additionally, JavaScript map events can be set up to respond to specific
user actions, such as mouse clicks, drags, and zooms (Petroutsos, 2014). This was a valid option
for this project, as the desired output was a simple web map with basic functionality.
The Google Maps API was considered but deemed inappropriate for this project. One
reason for this decision is that the company through which the project was being conducted was
already using a different web mapping solution that was readily available. Thus, setting up a
different option would be unnecessary. Google Maps requires an API key which is used to
monitor the usage of the web map. When the map reaches a certain threshold of user requests, it
is no longer free to use. Additionally, the user interface of many embedded Google Maps
applications is not as streamlined or visually pleasing as other available solutions. For these
reasons, the Google Maps API was not chosen as the method for the web map implementation.
2.3.2.2. Esri Web AppBuilder for ArcGIS
Esri Web AppBuilder for ArcGIS is another valid option for web map implementation.
Web applications with simple, pre-made widgets can be quickly configured if the user has an
ArcGIS Online account with a subscription. It would be possible to complete the project using
the ArcGIS Online and server subscription through a student account with the University of
Southern California (USC). The project goals involve creating a simple easy-to-use web
application, which would be met with the simple widgets available in Web AppBuilder.
16

Esri Web AppBuilder was not chosen for this project for two main reasons. First, the
MAW staff intended to have a solution that would last well into the future. This would not be
sustainable if the data and applications were to be hosted using a USC student subscription.
Second, the techniques used by the company the project was conducted through do not involve
the extensive use of ArcGIS Online.
2.3.2.3. Geocortex Essentials
Geocortex Essentials 4.8 was chosen for this project because it is an existing set up used
by the company conducting the project. It was ideal to adopt the web application methods
already in place. Geocortex Essentials by Latitude Geographics is a solution for web map
application implementation aiming to spare users the time and resources needed to single-
handedly develop customized applications. It offers many features and capabilities including
accessibility, reporting and printing, forms, charting, workflow, security, integrations, and instant
search. It uses the ArcGIS server platform and generates web applications that are desktop and
mobile friendly (Latitude Geographics Group Ltd. 2017).
2.4. Landscape Irrigation Systems
As a prerequisite to this project, it was necessary to become familiar with the basic
processes and structures involved in a landscape irrigation system. A landscape irrigation system
is composed of irrigation zones and their corresponding control valves. The control valves can be
for drip systems or sprinkler systems. Drip systems slowly feed water to an area through a series
of flexible tubes that have been placed among the plants. Sprinkler systems feed water to an area
quickly by spraying it in various directions and distances. Remote control valves can be wired
back to a controller station for remote and automatic operation. There are main lines, which are
17

connected at the water meter connection for the property, and lateral lines, which branch off
from the main lines. Backflow prevention structures are installed to prevent water from flowing
back into the main system, usually near the water meter connection.
Hose bibs, also called garden valves, are above-ground features that can connect to hose
tubing for manual watering. Quick coupling valves are like hose bibs, as they can be used for
quick and temporary access to the water supply, however, they are generally covered inside
irrigation boxes. Other valves include isolation ball valves and gate valves, which manipulate the
water service to smaller regions of pipe. They can be used to turn smaller pipe sections on and
off (Rainbird Corporation 2017). Figure 3 and Figure 4 show some of these structures as they
looked on the campus during field collection.

18

The MAW campus mostly uses three main brands of irrigation materials: Rainbird,
Hunter, and Toro. Identifying these brands helped to locate assets in the field and look up their
functions at the manufacturer websites when needed.

19

Chapter 3 Methods
The methodology for the project was fully planned in the beginning but adjusted throughout the
duration of the work to accommodate several unexpected challenges that were encountered.
There was an active construction project on the campus at the start of the inventory process that
made it necessary to wait to collect features in the area until after the construction was complete.
This also made the aerial imagery outdated as a basemap, requiring some new methods to be
developed to adapt the project. Section 3.1 outlines the project workflow that was initially
planned. Section 3.2 lists the technology and hardware requirements as well as the initial data
requirements. Sections 3.3 and 3.4 discuss the completion of the project through two main steps:
Data Collection and Application Development.
3.1. Workflow
The project required two main steps: data collection and application development. Data
collection involved initial research, field collection, and data development. The application
development involved the creation of new hardcopy maps, the development of a web application,
user training, and user feedback. These steps are illustrated in Figure 5.

3.2. Requirements
3.2.1. Technology Requirements
This project required several technologies. Special equipment was needed for the field
collection and specific software was needed for the data processing, data editing, and application
development. These project technology requirements are summarized in Table 1.

3.2.2. Data Requirements
This project demanded the collection and creation of all the features for the MAW
campus irrigation system, which made up the bulk of the project data. However, some initial data
items were required to start the project. The input data is summarized in Table 2.

3.3. Data Collection
3.3.1. Preparation
The first step was to gather all existing documentation of the system. MAW staff scanned
all their hardcopies to make this step easier. Digital copies of the relevant source documents were
obtained. These included construction plans and hand-drawn maps that ranged from the 1980s to
the present. Using these documents, an initial list of all the features relevant to the system was
drafted to serve as a guide for field collection and the final map legends. This list was then
presented to staff for review, as recommended by Tomlinson (2013). However, the staff did not
seem to have a complete knowledge of irrigation systems, so little guidance or feedback was
received at this step. Because of this, it was decided that including more detail rather than not
enough detail would be a good approach for the field inventory.
The next step was to create a base map of the study area to provide context and a
background for final maps. It was important that the aerial imagery available was from 2015,
recent enough for use in the project. Creation of a basemap involves choosing a map projection,
digitizing buildings, points of interest, and any other additional features such as walkways
(Gosch 2016). Creating a base map helps with orientation, deciding the scale and accuracy
needed, and the overall project scope. California State Plane Zone V was chosen as the map
projection because it is the local projection for Santa Barbara County. The basemap also revealed
that the project would be covering a small area and thus required more precise and accurate final
data, at least sub-foot accuracy. The basemap is shown in Figure 6. When the project started,
there was an area of the campus closed off due to building demolition and construction. This is
shown in the polygon outlined in red and white.
23

Figure 6: Initial basemap
The construction was completed later during the project, making it necessary to update
the basemap. The aerial imagery was therefore outdated and did not show the new buildings, so
the changes were digitized using the construction plan documents that were received from the
client. Construction drawings were georeferenced in ArcMap and the new buildings inside the
24

construction area were digitized off the raster. This process is shown in Figure 7. The final
basemap is shown in Figure 8.

25

Figure 8: Final basemap of the campus after the initial construction work was complete
3.3.2. Field Collection
The first step of the field collection process was to meet with the staff members who
regularly work with the irrigation system. Three different staff members agreed to walk the
campus and share their general knowledge of the system. This helped to learn where some of the
major structures were and what they looked like. The meetings revealed that some of the
26

controller boxes would be locked, requiring contact with a staff member who could unlock them.
Meeting with staff also established a relationship so future questions could be asked and
addressed in a timely manner. Staff members overall expressed a general lack of knowledge of
the system, which explained why they asked for assistance in the form of GIS.
Walking the campus with staff members made it possible to plan the basic structure and
design of the data to be collected. The highest priority GIS layers to be completed in this project
were the controller stations, control valves, and irrigation zones. The controller stations are boxes
that are wired to remote control valves, enabling users to turn valves on and off remotely. These
controller stations can be represented by point locations in the GIS data. Control valves control
the water supply to irrigation zones, either through sprinklers or drip tubing. Not all control
valves are wired back to controller stations, these are called manual control valves. Control
valves can also be represented by point locations. The irrigation zones themselves are
represented by polygons, illustrating the area that receives the water when its associated control
valve is turned on.
Main lines and lateral lines are represented with polyline features. Backflow preventers,
valves, hose bibs, and sprinklers are all smaller features within the system, and are represented
by point features. There were several structures encountered during the field inspections that
could not be identified as one of the assets previously mentioned, so a category of miscellaneous
point features was also included. This was done to keep potentially irrelevant data out of the
main data layers, but still preserve the excess data in case it was needed later. Lastly, assets that
were visible above the ground but were broken or disconnected were included as an abandoned
point. This was meant to help staff members begin to identify areas of the campus that are not
part of the active system. MAW staff could then decide to reconnect old structures back to the
27

system, leave them disconnected, or remove them altogether. For example, there were several
old sprinkler heads found that were capped closed and left in the ground, as well as hose bibs
that would not release water when turned. Figure 9 shows all the data layers that were initially
planned for the field collection process. The layer names are shown in blue and the attributes are
shown in white.

Figure 9: Plan for field collection of GIS data layers and attributes
The initial field collection entailed walking the campus building by building and tracking
the collection areas. A Trimble GPS unit running ArcPad 10 was used, and photographs were
taken of each structure collected to assist with identification and location adjustment. Assets that
were inaccessible, such as those within bushes, were collected using a measuring tape to measure
an offset distance. This method was chosen over usage of the Trimble device’s laser range finder
because it was simpler and faster for structures that were mostly covered with foliage. The field
data was post-processed in Trimble Pathfinder Office using the base station in Tajiguas, CA. The
28

campus has heavy tree cover in many areas, so the photographs showing locational context were
important for manual adjustments that would be needed later in the office.
After completing more than half of the inventory, it was decided that GPS collection was
unnecessary in some smaller areas where structures were under too much tree canopy or simply
too close together to discern in GPS data. Instead, the basemap was printed out and structure
locations were carefully sketched in the field. These marked-up maps were then taken back to the
office where they were used to digitize the features in ArcMap. Figure 10 shows an example of
such an area near Controller C where the valves were simply too close together to collect with
the level of GPS accuracy available.

3.3.3. Data Development
The field data was used to create the final data layers in ArcMap 10.5.1. The initial plan
was to use the field data as a starting point and compare the information against the as-builts and
other drawings to estimate configurations. However, the documents did not match the true field
configurations closely enough, making it necessary to rely completely on the field data to create
the new features in ArcMap. The lack of accurate documentation also proved to be a big
challenge in regard to creating underground pipe data, so that task was set aside and reassessed
later in the project.
The documents were inaccurate in some areas, and other areas were missing
documentation altogether. For example, some maps referenced control valves that could not be
located in the field, while other irrigated areas were not included on any of the documents
altogether. Because of these discrepancies, it was deemed necessary to do field testing of the
entire campus. This involved manually turning control valves on and off to reveal what zones
they controlled and what the boundaries were. Each control valve was manually turned, then the
shape of the zone was sketched on a paper basemap to later be digitized in ArcMap. As it
became clear, zones were assigned a control valve ID as an attribute to track which valve
controls which zone. Staff members were a helpful resource for the field testing, providing
another pair of eyes to check for water flow in the test areas as well as assistance with turning
valves on and off.
During the field testing stages, there were several areas that were identified as problem
spots that required further testing and involvement with the landscaping staff. These question
areas were documented, and maps were created that summarized each question. This allowed for
easy communication of issues to staff members who were then able to resolve the questions on
30

their own time. There was a total of five question maps made during this process. Figure 11
shows one of these maps. It includes three questions about areas that could not initially be
identified as part of a zone. These were temporarily numbered as “unknown” zones so they could
be easily referred to. For this specific area, MAW staff noted the zone UNKNOWN09 had been
disconnected as a part of the construction plans but had since been reconnected with zone A09.
Zone UNKNOWN03 simply had drip tubing that was heavily buried, and it was concluded that it
received water with zone A26. Lastly, zone UNKNOWN07 was discovered to be controlled with
zone B06 after a second round of testing. The other four maps contained similar questions that
were addressed with the same method.

Figure 11: Example of a map created to organize questions for the MAW landscaping staff
The data was finalized in a flat, shapefile structure due to the need for it to be published
as online map services. However, certain steps were taken to provide the major relationships
31

between the layers if they were to be converted to a geodatabase in the future. Figure 12 shows a
diagram of the final data structure, showing connections and common fields for a potential
relational database format in the future.

Figure 12: Final data structure showing potential relationships for future database format
3.4. Application Development
3.4.1. Map Creation
After the data was developed, it was used to create new maps of the system. There was a
total of seven controller zones on the campus that were each individually mapped. Each
controller box was measured for size so custom page sizes could be set for each map. This
ensured that the maps, when printed, would fit into their controller box. These maps are
discussed in more detail in Section 4.2.
32

3.4.2. Web Map Application Implementation
The final data was published to map services using ArcGIS server. These map services
were then read by Geocortex Essentials 4.8, which provides an interface for web map application
configuration within the browser. This setup is shown in Figure 13.

Figure 13: Web application setup
A total of three map services were created. The first was the “Irrigation” service, which
included all the point-type surface assets. Second was the “Irrigation Zones” service, which
contained just the irrigation zone polygons. This was isolated to a single map service because
Geocortex Essentials only allows for transparency slider adjustments within the application on
entire map services. It was important for the user experience to provide the ability to adjust the
transparency of the zones without also making the point features transparent. Last was the
“Campus Features” map service, which included all the basemap layers. Figure 14 shows the
map services in ArcCatalog stored within a folder to separate them from other unrelated map
services.

33

3.4.3. User Training and Feedback
Once the final map products were created, the intent was to train the users, so they could
use and understand the new application. A guide document was prepared which covered all the
basic buttons and functions on the web application. Because of the complexity of the project and
lack of communication between landscaping contractors and MAW staff, there was delay in
identifying more than one user for the initial feedback process. A meeting was held where the
campus facilities manager was given the guide and walked through the map application. This
meeting allowed him the opportunity to ask questions and provide initial feedback. In the future,
all potential users will be asked for final feedback after using being trained. Ideally, the final web
map application and maps will have met their needs and will be used to manage their system
going forward. The need for a more expanded user assessment is discussed further in Section
5.2.5. The guide document that was provided to the user is included in Appendix C.

34

Chapter 4 Results
Numerous data layers and map products were generated as a result of this project. GIS data for
the campus was created to represent base information as well as the irrigation system. The
creation of this new data was critical in order to create the final map products. The GIS data was
used to create new controller maps to be printed and used by staff members. It was also
published and displayed on a web map application, allowing users to interact with it in a web
browser. Section 4.1 summarizes the data that was created for the project. Section 4.2 describes
the creation of the new maps for each controller box. Section 4.3 covers the web map
application’s basic structure, interface, and functionality.
4.1. Completed Base Data and Irrigation Data Layers
The completion of the project depended on the creation of numerous data layers. These
data layers were necessary to be used for creation of the controller maps using ArcMap as well
as for use as map services on the web application. The final base data was comprised of three
layers. Buildings were polygon features representing the footprint of each building on the
campus. Points of interest were point features that were used to label important campus features
varying from gardens to firetruck access gates. Table 3 summarizes the total number of features
that were created to represent the campus base data.

The irrigation system was comprised of nine data layers, all point features except for the
irrigation zone polygons. Pipeline data was included in the initial project plan, but it could not be
completed within the project time window. The challenges regarding the pipeline data are
discussed in Chapter 5. Table 4 summarizes the total number of features that were created to
represent the campus irrigation system.

4.2. Individual Zone Maps for Each Controller Box
Controller maps for all seven controller boxes A through G were recreated using the new
data. The maps only included a few of the data layers due to their small size. Each map shared
the same legend, which is shown in Figure 15. Two controller maps are discussed in this section
in detail to show a comparison between the old maps and the new maps. Appendix B shows the
additional controller maps that were created but not included in the body of this paper. For
comparison, the additional old controller map counterparts can be found in Appendix A.
36

Figure 15: Common legend for the controller maps
Figure 16 shows the results for the area around controller C. The left panel shows the
map that had previously been used. The right panel shows same area after the project was
completed. The original map shown in the left panel was found to be incorrect. It showed only
six zones when there were seven remote control valves. It highlights a zone in purple showing a
continuous irrigation zone that was actually found to be divided into two using valves C01 and
C07 as shown in the right panel. It also delineated larger zones along the eastern side that were
not watered by controller C at all. These erroneous zones are highlighted in light blue in the left
panel. These zones actually corresponded with controller A entirely, and were not associated
with controller C.

37

Figure 16: Comparison of new controller map to old controller map for area C
Figure 17 shows the results for the area around controller E. The top panel shows the map
that had previously been used. The bottom panel shows same area after the project was
completed. It is clear that the original map was incomplete, as it did not reference the battery-
controlled area around the perimeter nor did it show sprinkler zone E02 on the eastern side. Not
only was it incomplete, but it was also erroneous, showing the light green area as continuous
when it is actually split between E01 and E03. The new map shows the location of controller E
itself, the associated remote control valves, and the corresponding zones that receive water. It is a
more complete picture of the area showing all related structures and how they feed water to each
location.

4.3. Web Map Application
4.3.1. Interactive Web Application Interface
The final web map application can be accessed in a web browser by a URL shared with
the users. A MAW staff username and password was set up requiring users to login. Figure 18
shows the web application as it looks once login credentials are accepted and it is initially
opened in Google Chrome on a laptop computer.

Figure 18: Web application interface
4.3.2. Functionality: Navigation, Analysis, Print, and Search
The application has a toolbar with four tabs: Home, Mark Up, Analysis, and Print. All the
tabs and associated tool buttons are shown in Figure 19. The Home tab contains basic tools
essential for navigating around the map such as pan and zoom. It also contains a basic export tool
which saves a simple graphic of the current map view. The Mark Up tab contains tools that allow
the user to add drawings to map. There are options to change color and line types, as well as add
text annotations in differing fonts. Drawings can be exported to different formats and saved, for
40

example, vector drawings can be downloaded in shapefile format. The measure tool allows the
user to measure on the projected map area. Distance and area measurements can be added as
drawings to show dimensions of map features.

Figure 19: Tabs and tools within the web application toolbar
The Analysis tab contains tools that help the user interact more deeply with the map
layers. Users can do a simple mouse click and drag to identify features on the map and view their
attributes. The Query tool allows for more complex data interaction. Users can set clauses and
return data that fits their query statement. For example, Figure 20 shows a simple query setup
41

that returns all the control valves that are related to controller A. Additional conditions can be set
to find map features that have specific qualities. The Filter tool follows the same concept but for
the visual map area. The user can set desired conditions for a layer and apply a filter to the map
to make only those features that met the filter conditions visible.

Figure 20: Example of the Query tool in the Analysis tab
The Print tab has a tool that allows users to generate and download cartographic maps in
various formats. Print templates of varying sizes and orientations were configured and can be
populated by data from the map application when the user makes a request. The user can choose
a print layout, output format, resolution, scale, map title, and compilation date. Figure 21 shows
the options available for map printing in the application. Figure 22 shows an example of a map
that was created using the Print tool. The application populates the custom print template with
the map layers the user made visible and outputs a clean, cartographic product. User mark up and
measurements that were added to the map area are also included on the generated map files.
42

43

The map area is configured with map tips for most of the features. Users can click on a
feature to highlight it and display a pop-up window with a summary of the feature’s attributes.
An example of a map tip is shown in Figure 23.

Figure 23: Example of a map tip for an irrigation zone feature
Finally, there is a search bar on the top right corner, and layers can be set to participate in
global search. Users can type in any desired term and the application returns results containing
that term. For example, the user could search for a particular building on the campus, or find a
valve by its ID.

Chapter 5 Conclusion and Discussion
There were many challenges faced during the project. The documents that were planned to be
used to validate the data were too inaccurate and staffing for the landscaping turned out to be
very disorganized and spread thin. These challenges combined with the lack of time made it
necessary to plan for several future improvements such as additional data collection and field
work. Section 5.1 discusses the challenges and limitations of the project in more detail. Section
5.2 outlines the plan for future improvements on the project. There were some shortcomings in
terms of project success, mostly related to the lack of pipeline data and the nature of the
contracted landscaping support. The project overall met its objectives because the corrected
controller maps were completed, and the web application was well-received. The overall
conclusions and achievements of the project are discussed in Section 5.3.
5.1. Challenges and Limitations
5.1.1. Lack of Accurate System Documentation
At the start of the project, it was believed that the system was fully documented in the
form of construction drawings and plans. However, the provided documents ended up offering
very limited usable information. They were not representative of the surface features that were
collected in the field. This made it difficult to gather information from the documents with any
level of confidence.
5.1.2. Dispersed and Limited Staff Knowledge
The campus facilities director was the main client, as he initially requested the GIS
services. However, he was not knowledgeable of the irrigation system and was not the direct
staff responsible for tending to the landscaping. The campus has a unique situation in that they
45

have contracted out their landscaping services to several different companies throughout the
years. Thus, the facilities director passed us on to several people from different landscaping
service companies in the process who all had bits and pieces of knowledge to contribute,
depending on which areas of the campus they had worked.
It was initially thought that one of the campus groundskeepers would be the main contact
for questions related to the field collection and testing. However, the meeting with him revealed
that he was reluctant to participate in the inventory process and turned out to not be very helpful
in terms of overall system knowledge. It was later noted that their main landscaping staff were
with a contracted company called Plowboy. Two Plowboy supervisors were briefed on the
project and its goals. They were able to identify and contact two field staff members who worked
on the campus landscaping several days each week who were available to meet and help
troubleshoot questions. It was later revealed that there was another landscaping contractor called
Brightview that was involved with several construction projects in the past, including the recent
construction project highlighted in Figure 8.
There were also additional contracted companies that had been involved with the campus
landscaping in the past, and it was a convoluted process to meet with separate contacts and
discover new contacts along the way. The lack of communication between all the various
contractors made it clear why the facilities director wanted to update their maps and begin to
create a common tool for the system going forward.
5.2. Future Work
5.2.1. Revise Data Structure
Using a flat shapefile format was necessary because of the existing company workflow
and setup with ArcGIS Server and Geocortex. In the future, it would be productive to upgrade
46

from shapefiles to a geodatabase with relationships and topology. This would make it easier to
edit the data when the system is altered. Additionally, this would provide the configuration
needed to eventually allow the users themselves to make simple edits to the data in real time
using the web application. It would be efficient to have the users take more responsibility of the
data in this way. As mentioned in Section 3.3.3, some small steps were taken toward this end
goal when setting up the attributes for each data layer. However, there are still additional
challenges that need to be overcome before the web application can allow for real-time user
edits.
5.2.2. Collect Additional Attribute Information
The new data could benefit from more detailed attribute information. The next step
towards asset management after completing a GIS inventory is condition assessment (Heltzel
2003). With the GIS features as a base representing the accurate locations of all the assets, each
asset could then be assessed for its condition. Adding this information to the web map would
allow for easy viewing of condition information and enable MAW staff to more easily see where
maintenance is needed and could help them reduce the number of leaks and breaks in their
system.
Additionally, collecting the flow rates for control valves would provide more insight into
the overall water usage of the campus. This would be helpful for MAW staff to know since they
stated they have had concerns from their water district in the past.
5.2.3. Create Pipeline Data
MAW staff originally requested maps for their entire landscape irrigation system. This
request was partially fulfilled by this project. The project successfully mapped the surface
features of the system in a full inventory and resolved confusion with irrigation zones as they
47

relate to each control valve. The shortcoming of this project was the lack of maps showing
precise locations of irrigation mainlines. A major issue MAW staff have is that they do not have
confidence when excavating during construction projects, as they have had a lot of accidents
hitting irrigation pipes underground. When they have leaks, they are unable to isolate the
affected area of the campus and instead are forced to turn off water to the entire campus when
these breaks occur. This issue was discussed with MAW staff and it was concluded that the
desired pipeline dataset could not be created as initially planned by using the GIS inventory in
combination with the construction documents. This was simply because the construction
documents were incomplete and did not parallel the field inspections. In the future, a pipeline
tracing project would be necessary in order to accurately map the mainlines in the GIS. This
would involve hiring a contractor to conduct the pipe tracing work and provide a deliverable
showing where all the relevant pipelines are located.
5.2.4. Label Control Valves and Control Boxes in the Field
New GIS IDs were assigned to assets during the project and it will be necessary to tag the
remote control valve lids in the field so they match the new maps and the web application. This
will also require the establishment of a method for updating the lids every time the data is
updated. For example, if any new remote control valves are added to the system they will receive
a new GIS ID and will therefore need to be tagged with their IDs after they have been added to
the GIS.
5.2.5. Train and Receive Feedback from More Users
The user feedback portion of the project was planned to be much more thorough. Within
the project timeframe, it was only possible to train and receive feedback from one user. It was a
meeting where the user was given the guide document and shown the web application
48

functionality first hand. Informal feedback was received, and it was very positive in terms of the
final products. Before the project, staff had no access to accurate and updated campus maps.
After the project, they have new maps of their system and the ability to view and interact with
the data, as well as the ability to print their own custom maps. Negative feedback was mainly
that the final maps were still lacking the desired pipeline data as discussed in Section 5.2.3.
5.3. Project Conclusion
This project involved the creation of custom data and products. The process was a
valuable learning experience in terms of applying GIS to landscape irrigation systems in general.
The same methods and data concepts could be executed to map landscape irrigation systems for
any other study areas of any size. This is particularly valuable to offer as a service to new clients
who have similar problems managing their system and may need help with such a task. Similar
concepts can also be applied to different utility systems beyond landscape irrigation.
This project also helped to show the importance of adjusting methods and plans
according to challenges faced. For example, the data collection methods transitioned from using
a GPS unit for each point to the use of annotation on printed base maps. It was simply more
applicable to such a small study area at such a large scale. Additionally, the use of georeferenced
as-builts in combination with field measurements was helpful for positioning structures in areas
of bad GPS signal. These documents were originally meant to provide all the intelligence on the
system, but instead were used mostly for basemap purposes.
The project concluded by partially meeting the original objectives. The first objective
was to conduct a full inventory of the campus irrigation system. This involved countless visits to
the campus to complete the field collection. This objective was met as all the surface structures
were collected and mapped in the campus GIS. Cleaning up this data involved extensive testing
49

of valves and controllers. However, the data portion fell short because pipeline data could not be
created. The lack of pipeline data was noticed in the web application and contributed to the
shortcoming of the project overall.
The second objective was to recreate the maps for each controller box. This was
completed successfully, as each controller box received an updated map showing the associated
valves and zones. The pipeline data was not crucial for these maps.
The third objective was to create a web application that was impressive and usable for
management of the irrigation system. This objective was partially achieved. The application was
shown to the campus facilities director and he was very impressed with its functionality and
interface. He was pleased to find that he was able to interact with the data and print his own
maps. This would have completely met his initial request for new management maps had the
pipeline data also been included. Overall, it was a success because he expressed the desire to
continue using the web application and continue our client-contractor relationship to maintain
and improve the data.

Appendix C: User Training Document
MAIN SCREEN

Number Screen Element

Title Bar: Displays the title of the application and the logo or name of a particular organization.

Toolbar: The Toolbar contains the tools that control how you interact with the map. In some
applications, there are several sets of tools that are grouped by function. In more complex
applications, the toolbar can have multiple tabs containing groups of tools.

Information Panel: The Information Panel is an area that has multiple purposes. It is used to list
important information. For example, it displays Map Layers where you can select different layers to
hide or show on the map. If you do a search or you use an Identify tool, it displays a list of map
features in the Results List. At other times, the Information Panel contains a menu that you can use
to perform tasks, for example, print or export the map. Each time you use the panel for a new
function, it is opened in a separate tab that appears at the bottom of the panel. You can click each
tab to return to that function.

Zoom slider: Use this slider to zoom in or out on the map by clicking the + or - or by dragging the
marker up and down.

I Want To Menu: A menu of shortcuts to frequently-used tools. This menu tries to anticipate what
you will want to do most often.

Map: The map window where you interact with the map by zooming, panning, annotating, or right-
clicking to get more information.

Search box: You can type in the name of a feature to search for it on the map. It is also possible to
search map services.

layers in the Information Panel. The legend only displays symbols for the layers that are active on the
map. The legend items change with the scale of the map.
The Filter in the bottom right corner of the Information Panel allows you to limit the information listed
in the panel.

Base Map menu: Lists the Base Maps that you can select, for example, a street view that shows a
map or an image view that shows satellite images. The Base Map menu also lists any Layer Themes
if there are any in this application.

XY Coordinates: Allows for the display of the x, y coordinates that tracks the location of the cursor
within the map. You can set the format for each coordinate system with a list of formats to choose
from.

Scale: The current scale of the map.

Map Tip: Map tips appear when you click on a feature listed in the Results List, or when you use one
of the Identify tools. In some maps, if you hover over a feature on the map, a map tip appears.
Click View Additional Details to find more information about the feature in the map tip.

67

THE TOOLBAR
The toolbar in the application can contain any number of tools, groups of tools, or tabs containing several
groups of tools. It is usually customized to suit a particular purpose. Customization means that the toolbar
of your application may be very different depending on how it is going to be used. A simple application
may have only one toolbar tab with a few essential tools available.

Example of a simple toolbar

A complex application may have multiple tabs each containing many groups of tools grouped by function.

By moving the transparency slider to the left you increase the transparency % for the layers in the
Operational Categories.

Layer transparency set to about 50% (slider set in the middle)

84

SEARCH WINDOW
The search window performs a search on all the existing map layers within the application. Search results
are returned in a list organized by map layer. Clicking on an individual list item allows you to zoom to and
highlight the feature.

For example, you can search by Irrigation Zone. Searching by Irrigation Zone will return all features
related to that zone name (zone, control valve).

85

IDENTIFY RESULTS
Once you use the Identify or Search tools on features, you get a list of results. The results window has
several options to choose how you engage the information.

The results window shows a short synopsis of the
features that were identified. Results are sorted
by map layer.

Click on the desired category to see the individual
features that were identified inside that category.
For example, clicking on “(3) Control Valves”.

After clicking on an individual entry in the results window, the corresponding feature on the map is
zoomed to and selected. The results window then displays more detailed information about the feature.

86

PANEL ACTIONS MENU

Different reports may be available depending on what features are
selected.

The Result Actions Menu on the right end of features in the Results Window is similar to the
Panel Actions Menu, but is geared toward individual features and layers. The tool options
available in the Result Actions Menu that were not already covered in the previous table are
described in the table below. They may vary depending on what types of features are contained in your
results list, and if you click the menu from a layer result or an individual feature result.

Zoom to All adjusts the map extent so all results within
the particular layer are visible.

Save Results allows you to save the results (either all
those within the layer or an individual feature). The
result(s) are given a name and can be reopened during the
session.
Open Saved Results allows you to return to any results
that were previously saved during the same session.

Zoom to the selected feature in the map.

Move to the feature in the map without changing the
current scale.
88

Click to create a copy of the feature as a Mark Up drawing.
It can then be edited using the style and edit drawing tools.

Open a menu of advanced options for working with your
results.

Remove all features within the particular layer from the list
of identified features. Use this tool to remove unwanted
features from a list before using an export method.

Remove the feature from the list of identified features. Use
this tool to remove unwanted features from a list before
using an export method.

89

GEOLOCATION

Geolocation uses the device’s GPS capability to find your location and display it in the map
view.

The Find Me tool places a blue dot on the map representing your current location and zooms
to it.

The Track Me tool follows your location as you move without adjusting the map extent or
scale.

The Follow Me tool tracks your location as you move and pans the map extent as necessary.

Abstract (if available)

Abstract Many agencies today still use outdated paper maps and construction plans to manage their utility systems. Those using outdated information and methods can benefit from a digital upgrade. Geographic Information System (GIS) is becoming a common solution for asset management and utilities because of its ability to combine spatial and non-spatial information all in one place. This project implements a GIS for the landscape irrigation system on the Music Academy of the West campus in Montecito, California. Campus staff were using a series of disorganized and incomplete paper maps to manage their irrigation system. They also had no information about where the main line and lateral lines were, which proved to be problematic during construction projects and pipe leaks. Transitioning the paper maps to digital GIS format proved to be a good solution. Using GIS, spatial data collection methods, campus staff knowledge, and existing construction documents, new hardcopy maps and an online web map application for irrigation management were developed for campus staff. In the future, the new irrigation map data can provide efficient solutions for future campus facility projects such as water usage analysis and leak detection device placement. Creation of GIS data for irrigation and other utility systems will likely continue to be a solution for effective asset management in the future.
