[Gdal-dev] processing SRTM-3?

[Thom DeCarlo]

Oops, found another... issue. The SRTM documentation states that the NODATA
value is -32768 and the shell script accommodates that by setting the
appropriate value in the header file. However, it appears that the rest of
the gdal software assumes that the NODATA value is -9999. Is there any way
to tell the gdal_translate program to change any NODATA values it encounters
to be -9999?

Thanks,
Thom
