Thanks, adress is correct, your french is good Your maps works pretty well once you used GT to convert it to correct gdal format. I send you back all correct tif. To create your tif, you have to open QLandkarte GT then press F1->F6. Select create map collection, press the new button to createa new collection and give a name. Once it is ok you have to add your current tif to the collection and select a zoom range you want the map for. Once it is ok press save. From that in GT you can naviogate the map. Then use the select subarea tool to export the correct format to M. Fabrice
