The Utah Geospatial Resource Center (UGRC) is Utah's state GIS program, widely regarded as one of the best-run in the U.S. It maintains the State Geographic Information Database (SGID) and distributes authoritative statewide spatial data.
Coverage includes parcels, addresses, imagery, elevation, transportation, and administrative boundaries, available through an open data portal, downloads, and APIs. UGRC is the definitive source for Utah geospatial data.
