I'm using GDAL on a project to view RPF (A.TOC) format of CADRG based imagery. I see how opening the "A.TOC" results in a dataset with many sub datasets. What I want to do is programmatically (on the fly) merge several of the sub dataset into one new dataset so that when the user pans the imagery in the viewer it appears to be one contiguous image. I'm looking at what GDAL has to offer (as far as programmatic solutions are concerned) and it appears GDAL vector virtual format (VRT) may be a possibility. I could really use some pointers. Is this the right approach or is there a better way? A working example would be great, but thanks for any help.
