The Wasatch Front LiDAR elevation data collected 2013-2014 is now available as a service. These services utilize the .5 meter DEMs derived from the LiDAR collection. Once you have established a GIS Server connection to mapserv.utah.gov in the Elevation folder you will find the following layers:

Bare Earth DTM layers:

  • Elevation\Lidar2013_2014_DTM - use this layer to get elevation values, derive contours and generate surfaces etc.
  • Elevation\Lidar2013_2014_DTM_Hillshade
  • Elevation\Lidar2013_2014_DTM_ShadedRelief
  • Elevation\Lidar2013_2014_DTM_Slope

First Return DMS layers:

  • Elevation\Lidar2013_2014_DSM
  • Elevation\Lidar2013_2014_DSM_Hillshade
  • Elevation\Lidar2013_2014_DSM_ShadedRelief
  • Elevation\Lidar2013_2014_DSM_Slope

PLEASE NOTE: If using the services for geoprocessing (generate contours, custom surfaces, etc.) be sure to set the geoprocessing tool's Environment Settings - Processing Extent to something other than the default that will use the entire dataset and blow your computer up. For instance select a polygon feature class as your area of interest or select Same as Display. For most geoprocessing you will want to use the bare earth DTM Elevation\Lidar2013_2014_DTM.

Here is a link to an ArcMap layer file for the elevation data services to get you started.

The hillshade, slope, and shaded relief surfaces are reference raster mosaics.
