Topography of the Western US was developed using the USGS NED. It is a single, seamless TIF file originally designed to support the NASA RECOVER wildfire decision support system (DSS). Embedded within this image service are various raster function chains or templates that allow the user to easily view/analyze aspect, slope, and hillshade as well.

This layer was improved in 2022 by pitfilling to reduce errors in elevation values.
This layer was improved in 2023 by adding a meters to feet function allowing the user to instantly display and use elevation values in feet instead of the default (source) meters.
