Hi Gerd, r247 works not as expected. Let me explain it a little bit more. I would like to cut a area out of planet-osm. This osmconvert does. After this splitter should generate a areas.list out of this osm-extract (eg. dach.pbf, see dach.poly at the end of the mail). This areas.list should afterwards be splitted directly out of planet-file. splitter-r202 generates an areas.list for hole bounding box (max-top, max-right, min-left, min-bottom). So I have to tweak the generated areas.list manually, that it only covers the expected map-coverage. splitter-247 generates the same as r202.
