Hi Gerd, this is the way i create the germany + 50km + iceland .osm.pbf-file: First step is download from geofabrik (only about once a month): ..\bin\wget --no-cache http://download.geofabrik.de/openstreetmap/europe.osm.pbf Then i cut the interesting area(s), i'll attach the corresponding .poly-file: ..\osmconvert europe.osm.pbf -B=..\germany+iceland.poly -o=germany+iceland.osm.pbf I do this process only once a month. Normally i update the germany+iceland.osm.pbf on daily basis with the following command: osmupdate --daily --planet-url=http://planet.openstreetmap.org/replication/ OSM-Data\germany+iceland.osm.pbf OSM-Data\germany+iceland-new.osm.pbf -B=germany+iceland.poly -v This file was fed to splitter on a 32(!)Bit-machine with Xmx1376m without problems. Regards, Uli
