Hi, Your target projection is the so called Google projection, or epsg:900913, or nowadays officially epsg:3785. It is the projection used in OSM slippy map, but the native OSM data are in epsg:4326. Therefore you should warp the downloaded images _into_ epsg:4326, not from that. Unfortunately I cannot say what would be the correct source projection definition for your original images. An easy way to test your warped images is to download some OSM data in shapefile format and in epsg:4326 projection from Geofabrik.de, open the warped image with some GIS program like QGis or OpenJUMP together with OSM shapefile and see if they suit well together. Gdalwarp options are documented at http://gdal.org/gdalwarp.html but some further reading may be necesssary to understand what all the options mean. -Jukka Rahkonen- _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
