Folks, Андрей Мигаль (Andrew) has completed his Google Summer of Code image correlator project and I have moderately adapted the code and checked into GDAL trunk svn. Some information is available at:
http://trac.osgeo.org/gdal/wiki/Correlator http://correlatorgsoc2012.blogspot.com/ https://github.com/migal-drew/GDAL-correlator http://trac.osgeo.org/gdal/changeset/24868 While I have exposed a function with the following signature, I have not yet checked in any changes that would use this from an existing commandline program. My plan is to expose it via SWIG and write some demonstration Python scripts using it: GDAL_GCP CPL_DLL * GDALComputeMatchingPoints( GDALDatasetH hFirstImage, GDALDatasetH hSecondImage, char **papszOptions, int *pnGCPCount ); I have successfully use it to perform an image match between a UTM image and the same image warped into WGS84. I then wrote out the GCPS and use them to warp the the one to the other and got a good result. I will also document the GDALComputeMatchingPoints() function based on the extensive documentation already prepared by Andrew for lower level functions. Andrew has done a great job this summer, and I hope we will continue to evolve and exploit the new functionality developed.
