I have dataset imagery comes from IKONOS satellite, the dataset contains "imagery with 1m resolution - metadata - rpc file", the metadata file contains the information about "Sun Angle Azimuth - Sun Angle Elevation - Acquisition Date/Time", so is there any way to remove the shadows area from the imagery data?

edit: i used GCP with Socet GXP to generate high resolution DEM (1m).

I think this is an issue about topographic correction. For instance, you can refer to this paper "Topographic correction algorithm for remotely sensed data accounting for indirect irradiance" or "A Physically-Based Model to Correct Atmospheric and Illumination Effects in Optical Satellite Data of Rugged Terrain".
