GIS Map Data

Utah's State Geographic Information Database (a.ka. "the SGID"), was established by policy makers to ensure that GIS map layers were developed in a coordinated fashion and shared openly, without redundant effort. Roads, boundaries, addressing, parcels, aerials, elevation, etc...you’ll find it available for download and as web services from the SGID.

The vision for the SGID was created almost two full decades before the govenrment 'open data' and 'transparency' initiatives began hitting their stride. And, to the credit of the GIS community across the state, the SGID's GIS data resources are among the most mature and extensive in the nation.

Today, interoperable GIS server technology has diminished the importance of a completely centralized map data repository. But, it's actually more critical that the latest and best quality GIS data resources are readily discovered and accessed. And that's true for resources available to users as downloadable shapefiles as well as resources available as connections to live streaming data services. AGRC strives to ensure that the SGID stays current as a state-level channel to aide in the discovery, access, and use of GIS data resources.

Base Maps and Imagery

AGRC hosts aerial photography and pre-rendered base map services on its discover.agrc.utah.gov cloud-based server. After obtaining an organizational login, GIS users, CAD users, and web apps can connect to these multi-scale maps using the Open Geospatial Consortium WMS and WMTS protocols. The Discover service provides images and tiles in the Web Mercator projection, an industry standard for web map display.

Layers accessible from the Discover server include themed base maps built from local & state GIS data in terrain, lite, topo, and hybrid themes. Aerial photography offerings include the latest 6" statewide imagery licensed for state, local, & tribal government from Google, as well as public domain color NAIP, Wasatch Front HRO, CIR/NRG imagery, and the historic B/W DOQ series.

Until January 31, 2017 AGRC provided base maps from its mapserv.utah.gov server in UTM NAD83 coordinates. These base map services have been retired in favor of the cloud-hosted OGC services served through Discover.

AGRC's atlas.utah.gov website allows for a quick preview of the most popular base map services. Zoom in for richer map content, click the map for key location-specific info, and use the base map selector in the upper right corner to select your base map of choice.

Among the locally sourced map layers that AGRC incorporates into its base maps are: municipal boundaries, building-specific address points, road centerlines per UDOT specs, and State-stewarded public lands boundaries.

TURN GPS Precision RTK Network

The Utah Reference Network for GPS (TURN GPS) is a networked system of over 90 permanently located high precision GPS receivers, installed across Utah and neighboring states.

TURN GPS provides a real-time correction signal that factors out atmospheric variation between earth-orbiting GPS satellites and ground-based GPS receivers in the field.

TURN GPS Network Coverage
TURN GPS Network Coverage

Surveyors, construction crews, field mapping technicians, and GPS-controlled machinery are able to operate with up-to sub-centimeter precise measurement by connecting their existing GPS receivers to the TURN GPS correction service over a smart phone hotspot.

A partnership with state and local government agencies has allow TURN GPS base stations to be sited at existing Utah facilities in exchange for the partners' use of the system. One year subscriptions to the TURN GPS service are $600 per GPS device.

Application Development

There are many possible approaches to publishing data to web maps and web services. AGRC assists with a full range of web map solutions, from the simple to the most complex.

Our dev group specializes in custom applications, designed with agility to meet defined requirements, that maximize the communication, logical organization, and usability of information.

Some of our recent, and occasionally award-winning, work includes:


The Watershed Restoration Initiative website uses a shared web map to enable interagency project and resource coordination.

Crash Map (DPS / UDOT)

APIs and JavaScript Widgets

APIs available through api.mapserv.utah.gov enable common tasks like address location (aka geocoding) and map search (point-in-polygon query) to be built into web applications and data-handling processes without the immediate need for GIS-specific software. These API's are at the core of sites like Who Represents Me?, Who Taxes me? etc.

AGRC's dev group maintains a library of Utah-specific map widgets that provide common tools desired in web mapping applications. The library includes FindAddress (geocoding), TRSSearch (finds PLSS sections), and Sherlock (can be used to search for any feature in the SGID or layers in a map services. We also, on occasion publish customization for ArcGIS desktop like our geocoding api tool.

We are into git. By default, the AGRC dev team keeps its code current in AGRC's GitHub repository. If it's a web site, widget, desktop add-in, or even the content of this website itself, it should be findable, and open-sourced in the AGRC repo.
