I'm accessing a WMS server that doesn't provide geotiff as one of the format capabilities, but does provide PNG and KMZ.
I'm thinking that it should be possible to write a little shell script that would either:
Request KMZ and convert that to geotiff, using the implied SRS and bounding box info
Request PNG and use the WMS query bounding box and SRS to create the geotiff, perhaps using gdal or similar
Has anyone done something like this, or is there a better way?
