16.42. 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).
