[Gdal-dev] How to get georeferenced pixel?

[Andrew Finley]

Hi Michal,
Please find attached some c++ code that pulls utm (or anyother coord
system) point locations from a file, then picks the pixel values from an
stacked or unstacked image and writes the result to a file.  I just
wrote it yesterday and haven't had a chance to check it too much yet,
but it will get you started.  Let me know if you make any improvements.
cheers-
andy

there should be attached a parameter file, input file, and the .cpp file
