Just a note: I did not really create the vrt file by hand as I used one made with gdalbuildvrt. I only changed "sourceFilename". I tried the -separate flag and converted the vrt file in tiff. All is working as espected. However the vrt file is not readable correctly by QGIS. I just saw that QGIS was an old release (1.4 !) so I am going to upgrade it. More soon :) Y. -- Yves Jacolin http://yjacolin.gloobe.org _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
