Hello,

we wrote a working GeoTIFF loader a few years ago using Proj4 library.

The worts problem with GeoTIFF format is that it uses relative links to 
EPSG or ESRI definitions just with a number!! AND if somebody adds new 
definitions LATER the original database cannot solve them anymore!! REAL 
IDIOTS!! They should have ALWAYS included the FULL definition instead of 
just the "number"!! That way the GeoTIFF format would have worked 
forever! Now it just works until somebody adds a new entry to the 
database and some other idiot chooses to reference it in a GeoTIFF file!

But what so ever, you can try to live with this error by always using 
the latest ESRI/EPSG database with your GeoTIFF loader! (So, your 
GeoTIFF loader needs an ESRI/EPSG definition database to work.)

Regards: Janne
