[GRASS-user] ECW data

[William Kyngesburye]

Normally you would use GDAL compiled with the ECW library support.

BUT, I can't get it to work on OSX.  It always gives me invalid image  
errors, and others have the same problem so it's not just me.  I've  
asked ERmapper (uh, Leica) about it, but they only officially support  
10.3.9 PPC, which is not usable on 10.4 because of C++ compiler  
version differences.  I've asked in their forums for any user/ 
programmers that could help, but no response.

Strangely enough, GraphicConverter uses the ECW library and works, I  
think it uses different library calls to read them.  But GC loses the  
geographic info, and it doesn't handle large files very well.   
Because it works in GC, I also have a bug report for GDAL, but also  
no action on it yet.
