Geographic Information Science

The Geographic Information Science (GIS) Section is a support group that guides GIS implementation throughout UDOT. Our primary responsibility is to make GIS an integral part of business at UDOT by supporting the work of various groups in the central and region offices with  focused data and applications. We support UDOT's strategic goals; zero crashes, injuries and fatalities, preserve infrastructure, and optimize mobility, by providing easy access to and visualization of relevant data for improved decision making.
Our goal is a consistent and scalable GIS implementation strategy that will support the work of all groups within the department. GIS supports UDOT's emphasis areas by providing increased and enhanced access to data and analysis methods.
Integrated Transportation – Access to data helps UDOT understand, plan for, and build a transportation system
Collaboration – GIS data and tools facilitate and strengthen UDOT partnerships internally and externally
Education – Geospatial visualization improves internal communication and public outreach
Transparency – GIS tools provide user-friendly and intuitive access for internal users and the public
Quality – Quality work is enhanced by intelligent GIS data and tools
Innovation – Leverage technology to provide increasingly efficient solutions
UDOT GIS strives to provide powerful tools that allow access to relevant data for better and more informed decisions.  Our focus is on meeting the needs of the regions, our internal groups, and our external partners to support the UDOT vision, keeping Utah moving.

2017 Accomplishments

Data Access, Integration, Visualization and Transformation
The GIS team began using FME (Feature Manipulation Engine) in 2017.  This new tool allows offers over 450 transformers, making it easier to access, integrate, visualize and transform data.  UDOT's GIS Analysts have put FME to work providing solutions in many areas across the department, including those shown below.   
STIP Workshop Application and Live STIP
The collaboration and teamwork preceding the 2017 STIP Workshop supported all three of UDOT’s strategic goals by communicating project information to transportation commissioners, decision makers and stakeholders in way that was easy to understand.  Making the best decision about projects helps UDOT meet is goals of zero crashes, injuries and fatalities, preserving infrastructure, and optimizing mobility.
Utah's State Map
The GIS Team worked with UDOT's Communication Group, the Tourism Department,  and local partners to update the state transportation map in 2017.
The map was awarded the 1st place ribbon in the State Transportation Map category at AASHTO's GIS Transportation symposium.

Output Measures

The graphs and charts below communicate the output measures collected by the GIS Team that will used to guide future growth and development of GIS at UDOT.

2016 and 2017
Tracking the types of applications the GIS Team is using to provide solutions across the department helps ensure UDOT is getting the best value out of their IT investments in terms of flexibility and maintenance.
(Commercial Off-The-Shelf) COTS solutions typically cost less, can be created quickly and have lower maintenance costs.  Custom solutions are the most flexible but take longer to develop and may have increasing maintenance over time.

Annual Goals

The graphs below show how the GIS team met their 2017 goals in three key areas; Data and Apps, Training and Outreach, and Integration. 
The GIS team is committed to monitoring the use of our data and applications to support decision making on future investments.  To achieve this we are performing a monthly review of all UPlan content, including all UPlan apps.  Google Analytics is being used to monitor any custom applications created by the GIS team.

Data and Apps

Tracking the number of new data layers, enhancements to existing custom applications, and the development of new custom applications, helps the GIS Team understand the department's investment in custom projects and plan to meet the future development needs.
2018 Targets:
8 New UGate Layers
4 App Enhancements
3 New Applications

Training and Outreach

Tracking the number of training meetings, conference session, and tutorials provides the GIS Team with data that can be evaluated against survey results to measure how well GIS is being integrated into UDOT culture.
2018 Targets:
10 Training Meetings
3 Annual Conference Sessions
4 Video Tutorials


Monitoring the refresh rates of business data into GIS and BI web applications ensures decisions across the department are being driven by the most current data available.
2018 Target: Improved refresh rate of 3 UGate data layers

Core Functions and Current Projects

The bulk of work completed by the GIS Team is ongoing and falls into one of the following five core functions:
1.  Linear Referencing System
2.  STIP Workshop Support
3.  Data Visualization, Interpretation, and Communication
4.  Data Management and Governance
5.  Customer Support
In addition to our core functions, we are working on two pilot projects:
UTRAC, Esri Insights:  Using Esri Insights to provide business intellegence for snowplow AVL data
STIC, Data Indexing:  Creating a federated index of data from multiple sources across the Department that will be accessible via UDOT Open Data
Additional GIS work and projects come in from requests made through the GIS Work Request form, which can be found at:  These projects are prioritized by UDOT's GIS Executive Committee, find the status of those projects in the table below.
