Hello, The code compiles because it is part of a bigger program. This is just the portion on Coordinate Transformation. Any additional comment is welcomed. I did not compile GDAL. I am using gdalwin32exe141 gdalwin32dev141 pre-built GDAL. Thanks for your help. Reinaldo At 01:25 AM

Vincent, I tried gdalwarp as: gdalwarp in.tif out.tif ERROR 1: Unable to compute a transformation between pixel/line and georeferenced coordinate for in.tif. There is no affine transformation and no GCPs. I guess gdalwarp needs GCPs in in.tif that does not have GCPs in it. I also tried
