RasterImage<Reflectance> + RasterImage<DEM> -> RasterImage<TerrainCorrectedReflectance>
Correct satellite imagery reflectance values for topographically induced illumination variations using a digital elevation model (DEM).
Problem it solves
Terrain slopes and orientations create artificial shadows and highlights in satellite imagery, distorting true surface reflectance.
