Peng,
I'm a bit confused. The Geotransform is only six doubles long. Is
it GetGeoTransform() that is returning the above values? If so,
why do you get eight values? Does GetGeoTransform() return
CE_None?
Can you provide output from the nitfdump program for the file? It
provides a lower level view of the key nitf information. You can build
this on windows by going to the gdal\frmts\nitf directory and building
with the command "nmake /f makefile.vc nitfdump.exe"
Best regards,
