Can someone take a look at relation 406175 (Skunk River and some related waterways in central Iowa)? With my most recent attempt at rendering with mkgmap (rev 1631) it doesn't show up at all. Prior to that it was the source of some flooding... As far as I can tell the relation is correctly defined, but maybe is is getting damaged by the splitter since it covers such a large area? I'm trying to generate a whole US map using extracts from the planet (currently using planet-100401): bzcat planet-100401.osm.bz2 | ~/osmosis-0.34/bin/osmosis -verbose --read-xml file=/dev/stdin enableDateParsing=no --bounding-box top=50 bottom=23 right=-66 left=-125 idTrackerType=BitSet completeWays=yes completeRelations=yes --write-xml file=usa-100401.osm java -Xmx4000M -jar ~/splitter.jar --cache=cache --max-areas=128 --max-nodes=800000 --mapid=70000001 --geonames-file=cities15000.zip usa-100401.osm <edit template.args> java -Xmx4096M -enableassertions -jar ~/mkgmap.jar -c template.args I'm using splitter rev 105 (the patch in rev 106 doesn't look like it affects me since I'm using a single OSM input file). -- Jeff Ollie
