    Description:
      Abstract: This is a raster GIS dataset modeling the appearance of shadows from topography in the Central African Republic. Created from a modified version of the 30 m Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM).
      Purpose: This dataset was created to improve visualization of topography in the Central African Republic.
      Supplemental_Information: This dataset should be used with the associated DEM, titled "The Central African Republic Diamond Database - Hydrologically Corrected Digital Elevation Model (30 m)"
