Thanks for looking into this. I added --sort after each input file name and it still gives the same error. The OSM map file was generated by osmosis, which I used to split planet.osm. java -Xmx1560m -jar /home/nav/scripts/osmosis.jar --read-xml file="/home/nav/temp/tile.63255095.osm" --sort --read-xml file="/home/nav/temp/eletile.63255095.osm" --sort --merge --write-xml file="/home/nav/temp/mergedtile.63255095.osm" thanks, Andy -- Andy PGP Key ID: 0xDC1B5864 _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
