Sorry to butt in with a question that must have been answered a few
times before.
I am looking for a solver (ready made or an algorithm to implement) to
derive an affine transformation matrix for a given coordinate
transformation based on a set of points with coordinates in each system.
Mike,
I think you are looking for:
int CPL_DLL CPL_STDCALL
GDALGCPsToGeoTransform( int nGCPCount, const GDAL_GCP *pasGCPs,
double *padfGeoTransform, int bApproxOK );
