    • Great Salt Lake TBDEM GeoTIFF

    Metadata Updated: January 21, 2026

    This section of the data release includes the topobathymetric elevation dataset of Great Salt Lake as an assimilated raster comprising interpolated bathymetry from 2005 and 2006 (Baskin, 2005; Baskin, 2006) and QL1 and QL2 lidar from 2016 (Utah Geospatial Resource Center, 2016). The bathymetric dataset was originally published as contour maps. The contours were interpolated to develop a digital elevation model that is readable by a geographic information system and compatible with topographic lidar data generated in 2016. Because the water elevation of Great Salt Lake has declined since 2005, regions of the bathymetric and lidar datasets overlap to provide a reasonable estimate of error. The topobathymetric dataset was generated with a horizontal projection of UTM Zone 12N, North American Datum of 1983, Geoid 12b at a 0.5-meter horizontal resolution, and referenced to the North American Vertical Datum of 1988 in meters.
