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)"
