Topographic Correction

This module provides a correction for shadows caused by topography on imagery. The correction provided is the C-correction, as described by McDonald et al 2000. A digital elevation model must be provided with the satellite data. Solar azimuth and zenith information will be imported from the original satellite data format, otherwise it must be provided.

Indices:

  • Digital Elevation Model - Band name of the DEM.

  • Solar Azimuth

  • Solar Zenith
