Hello, I'm trying to import and define the extents of raster GeoTIFF images. For some reason, after the update of ArcGIS 10 SP1 I am not able to define extents of these images such that the extents remain in the raster images after I convert them.
I've specified my extents several times through my code, but I don't understand why this doesn't 'take' in the final product.
Any ideas? Thanks for your thoughts in advance... My Python code is posted below.
