I believe that the GeoTools library can read and write GeoTiffs and
is based in part on the GDAL library.  You might be able to use that
as a basis for an IOSP.

Hi Pauline:

NJ library can write GeoTIFF in a limited number of projections, but theres no 
support for reading
geotiff into the CDM. It could be done if someone wanted to write the IOSP.

Its hard to write a general GeoTIFF reader well because of the thousands of 
projections one would in
principle need to support. Also, theres no canonical way to store time and 
vertical levels, and no
one apparently in charge of the standard for many years now. For these reasons 
we have decided not
to invest much time into that format.

If I had to do it I would consider a jni interface to GDAL.

Hi all,

I've been asked to check whether TDS supports GeoTiff files from one of
our clients.  They have thousands of these files and would like a nice
way to aggregate them to serve it out.  I tried adding a file to the TDS
catalog, but it wasn't able to read the file (invalid NetCDF file).
However, in the NetCDF javadoc, there is a geotiff class.  Then looking
at the NetCDF Java 4.0 feature list, it has only listed *generation* of
GeoTiff files.  Is it likely that TDS will support GeoTiff sometime in
the future?  I did also find a few pages with GDAL OPeNDAP Server, but
can't seem to locate a copy of the server that I can install and have a
look at...

Cheers,

-Pauline.
