Steve,
when you specify a proj.4 string to GDAL/OGR, it doesn't keep it verbatim but
translates it into its internal SRS model (based on WKT format). When it must
pass a SRS back to proj.4, it translates from this model.
During this translation, if it detects an explicit datum known by PROJ.4,
When trying to transform a projected coordinate (UTM 14) from WGS84 to
NAD83, using the OGRCoordinateTransformation class, my transformed output
point exactly matches my input point, even though I have specified valid,
non-zero +towgs84 parameters for the NAD83 coordinate system.
If I do the s
As your GDAL installation looks to work OK, you might get better help by the
GeoServer/ImageIOExt community as it might be more related to the
ImageIOExt/GDAL integration itself.

Thanks. I found part of the issue. Apparently
I had the ECW version of the library (instead of the base
one) and was getting a unresolved dynamic link error.
Now NITF is an available option. Unfortunatly, I can still
not get it to load. Now I am getting an error in the log about

David,
If you just need reading uncompressed or JPEG compressed NITF, you don't have
to bother with MrSID or ECW. Those formats are totally unrelated. Except if
you want to read JPEG2000 compressed NITF files, in which case you need to
have a GDAL build with a JPEG2000 capable driver (Kakadu, M
All:
Sorry for the newbie question. I have searched archives and not
seen an answer.
I am setting up a Geoserver system on 64 bit Linux (CENTOS) and
need support for NITF formats. I installed the lastest imageioext
binaries but none of the additional GDAL formats show up.
I have verified a
I am also using the netCDF driver to read weather data from a thredds
server. I am curious how the tag names for the metadata were defined in the
driver. For example, the CF convention for the central meridian is
"longitude_of_central_meridian" and in the netCDF driver it is
"central_meridian".
