That's a good question. I'm not aware of any free&open source conformance
testing software for GeoTIFF.
I could imagine at least 2 levels :
- checking that the geotiff keys and tags are properly encoded ("easy" level)
- checking that the projection info are properly encoding, ie checking that
for a given projection method, the appropriate parameters are there (from my
memory, this is not even specified in geotiff itself). This is often the level
where interoperability problems occur.
