Hi Greg. You can use osmconvert which should be able to read the output of splitter, e.g. osmconvert 12360002.osm.pbf -o=12360002-josm.osm.pbf In the meantime I'll try to find out if this is related to the pbf libraries. My understanding was that the pbf format should be up - and downward compatible, and splitter uses the "official" libs, I think JOSM as well, but maybe different versions.

Februar 2016 21:52 An: Development list for mkgmap Betreff: [mkgmap-dev] when I use SPLITTER to IMPORT om.pbf files into JOSM I get error I am trying to use JOSM for offline editing and osm.pbf files created by splitter r427 cause this error when importing into JOSM r9329 with the pbf import plugin: Could not read file '12360002.osm.pbf'. Error is: java.lang.IndexOutOfBoundsException: Index: 0 I think I saw a post that there might be missing meta data from the osm.pbf files produced by splitter. JOSM has a max of 50000 node for input files. Is there a different 'splitter' that JOSM can import?
