Hi all and Franck,
I use OGR and GDAL in a software that has to manipulate and convert UTM
and WGS84 coordinates and maps.
OGR/GDAL is very powerful and I'm very happy with it.
Nevertheless I have a (maybe stupid) question concerning UTM zones

Hi,
I originally posted to the GRASS list, but it was suggested that it
would be more appropriate here, given that GRASS uses GDAL for this
particular problem.
I'm in the process of importing sea ice concentration data from:

Thanks for responding Hermann. Yes, I tried using -s_srs EPSG:3412 as
well as the full PROJ4 string with the same result. When specifying
-s_srs, does gdalwarp ignore (override) the project information in the
hdr file?
If I include the Hughes 1980 ellipsoid in the hdr file (projection info

Even,
You are right. The point is how to take full advantage of the GDAL Java API choosing the right
approach to deal with the raster buffer on the client side.
Best regards,

Hermann,
I've reproduced what you observe with trunk too and created ticket
http://trac.osgeo.org/gdal/ticket/3217 with 2 patches that solve the issue. One
must be applied in libgeotiff, the other one in the GTiff driver.

Simone,
thanks for all this interesting information. I'm doing some experiment with Sun

I'm not sure what you are really measuring if you compare a C++ code versus its
translation to Java code. I think it just reflects the known slowdown of Java

I don't know if it will solve your problem, but EPSG:3785 is now
