pansharp
--------

This tool reads in a high resolution grayscale file and a low resolution
RGB file and produces a high resolution RGB file. The output image will
be at the resolution of the grayscale image and will cover the region
where the two images overlap. Both images must have georeferencing
information. This can either be projection information in the image
metadata or it can be a separate Worldview format XML camera file
containing four ground control points (if using the tool with Digital
Globe images).
