[Gdal-dev] Customized Raster Format support for ArcGIS

[Michael S. Rosen]

The string below refers to the GDAL headers and libs that can be used to
to make GDAL plugin drivers which can be called by ArcGIS.  Can anyone
point me to these? 

 I've built sample drivers using the trunk, staged them where ArcGIS
finds them (I can see the Load/Unload in the debugger) but they don't
seem to get called by the gdal13.dll that shipped with ArcGIS 9.2.  Is
there something else I'm missing?

Thanks.

Frank,

Great idea. The new branch will make this possible for 9.3, and in the
future
releases we can try to sync up with regular GDAL releases.

Thanks,
Gao, Peng
