Hi,
testepsg EPSG:3785 gives [1], whereas
gdalwarp -t_srs EPSG:3785 input.tif output.tif results into [2]
This looks like a bug, or not? I am using gdal 1.6.2

Dear All ,
Is there any utility in gdal libary which provides Image classification (
Supervised and Unsupervised) ?

Caio Simone,
I just downloaded imageio-ext to check how it does that but it looks like I
don't need to do that now, I can take you report instead. Thank you very much.
I will take a look on array pinning for a start.
I translated the GDAL Proximity [1] code to Java and I timed both of then with
Is it possible to define/set a coordinate system using GDAL? I
downloaded some data (from NSIDC) I know is in EPSG:3412.
(http://spatialreference.org/ref/epsg/3412/,
http://nsidc.org/data/atlas/epsg_3412.html)
The data is in bsq format, therefore requires a hdr file that I've been
piecing
The tiffinfo utility reports the number of columns and rows in TIFF
images, including BigTIFF images.

Ciao Even,
just wanted to add my 2 cents.
As you know for the imageio-ext project we have been using the
GDAL-JNI bindings (actually a modified version of them) for a while in
order to allow Java users to leverage on GDAL using the ImageIO
framework which standard in Java.
This way we also enabled

Ivan,
thanks for your testing (CC'ing the list as it is of general interest).
Actually, I also read on some sites that using ByteBuffer object versus regular
Java arrays is not always a win. Plus the fact that we must use a direct buffer
that has an extra allocation cost according to
