[gdal-dev] Conversion from WGS84 to NAD83(EPSG:26912 - NAD83 / UTMzone 12N )

[Eli Adam]

Sumit,

     Looking at EPSG:26912 on spatial reference, http://spatialreference.org/ref/epsg/26912/ and your longitude coordinates (74-76 East, no less) makes it questionable if 26912 is an appropriate projection.  That projection looks valid for western Mexico, and midwestern US/CA.  You data looks to be roughly in Asia.

     I think that error says that it is not in a valid area of the target projection.  

Bests, Eli
