Implementing C-factor topographic correction into IMAGINE

Topographic correction of satellite or other Remote Sensing images is not trivial. Most methods assume the surface to be Lambertian. Non-Lambertian methods are more general but require user-defined parameters (Minneart) or regression methods.

We used our robust image-based regression method and created a process into IMAGINE environment (Model) to perform the whole topographic correction process. It is somewhat tolerant to DEM errors, disabling too big slope estimates and over corrections.

The C-factor method has been considered the best topographic correction method in some reviews. Still it is not available as such in much COTS Remote Sensing software.
