LiDAR of the Salton Sea

Using a Geographic Information System, existing datasets were compiled and processed to create a merged topographic/bathymetric basin of the Salton Sea. The bathymetric acoustic sounding survey was collected in 2005 by the Bureau of Reclamation and processed at a 2-meter resolution. The 2010 LiDAR data used came from the USGS and captured the shoreline as well as 5km buffer around the Salton Sea.  The LiDAR-derived surface was produced from 1-meter DEMs, and was collected with the vertical datum NAVD88, and horizontal datum and projection of NAD83, UTM 11N. In order to merge the bathymetry and LiDAR, the LiDAR was resampled to 2-meter resolution. The two raster datasets could then be geographically and statistically merged. In image layouts where there are perspective views, or 3D visualization, a 100x exaggeration was used to enhance the depth of the lake. The Salton Sea is very shallow, so in order to see some of the elevation features, it was necessary to vertically exaggerate the depth of the lake. A Satellite Image was used in the background of the map and came from the Landsat 8. The Image Metadata: 30m Resolution, 6 Bands Stacked (bands 2-7) Acquisition Date = 6-16-2013; Path/Row=39/37; Scene ID= LC80390372013167LGN00
