I have a large amount of large GeoTIFF images. Their names are arbitrary and the person that created them does not work here with us anymore.
I need to do some programming experiment. How can I pick a small subset that covers adjacent ground?
I have been tasked with creating a prototype of a slippy map with these GeoTIFF files; they are high resolution aerial imagery of the town we're based in. I want to experiment with GeoServer, as advised in another question here, but the files take so much space that I'd like to start with a smaller subset. So I would like to pick a small number of these GeoTIFFs, and to make a sensible slippy map they should be adjacent - covering areas of ground that are next to each other.
