Ok. I was looking for some rules that translate the [20000, 32760] range to EPSG codes. >> OGC started a SWG to do this GeoTIFF spec refinement work.

Is it a public one ? The archives are private so you probably need to be an OGC member to access them. I’m not working at Luciad anymore so I can’t be of much help myself; I haven’t registered as an individual member. My old Luciad account is still active which gives me access to the archives, but I’m not sure how long that will remain the case.
