I did tests and all gave the result expected. It seem to be a problem
with the origin of the result file (see attached file). The application
has taken the origin of the file 056n05_0100_deme.tif instead of the
origin of the file 056n05_0100_demw.tif. What do you think ?<br>
<br>
For your information the files are in geographic coordinate system.<br>
