Imagery plus Overlay base maps
Lite base map
Do you need a quick, fast base map for your GIS, CAD or web services?
AGRC provides several multi-scale base map and imagery service options that deliver pre-rendered base map tiles to your platform as fast as your internet connection will allow. The Discover services utilize a Web Mercator WGS84 coordinate system (wkid: 3857). Information about transformations between different coordinate systems can be found here under
Coordinate System and Datum.
Web Mercator Services on Discover
AGRC’s cloud-based server Discover provides imagery and base maps services in Open Geospatial Consortium (OGC) standard Web Map Tile Service (WMTS) and Web Map Service (WMS) in the Web Mercator WGS84 projection (wkid: 3857).
One featured offering from Discover is statewide 6 inch imagery collected and licensed by Google. Due to this licensed content, access to the Google imagery is only for Utah’s cities, counties, special districts, state agencies, K12/Higher education, and tribes and contractors and formal partners of the immediate licensees free of charge. To obtain access to the Google imagery on the Discover server you need to fill out and understand the Organizational Usage Agreement available from the Discover page. Once the Organizational Usage Agreement is completed, you will receive information about the services and URL links to access the Discover server. The URLs to access the server will contain a quad-word (ex.
https://discover.agrc.utah.gov/login/path/your-unique-quad-word/) unique to each user or organization.
If you are not covered by the license agreement for the Google imagery service you will need to fill out the Discover Server Access form for access to the non-licensed services. Once the form has been completed, you will receive information about the services and URL links to access the Discover server. The URLs to access the server will contain a quad-word (ex.
https://discover.agrc.utah.gov/login/path/your-unique-quad-word/) unique to each user or organization. If you already have a Discover account, you do not need to create another account to access the base maps and imagery services.
