I am creating a multi-layer map. On my test, I'm using a single osm file and I was able to create some form of hillshading effect using elevation polygons and dithering with typ: http://farm6.static.flickr.com/5298/5488803441_a65e23d54c.jpg What I want is to split the data into three layers (coastline, hillshade and osm data - pois, lines and polys). Following the advice here: http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2010q4/009484.html I have this args file: ========== gmapsupp code-page=1252 latin1 country-abbr=PHL country-name=PHILIPPINES generate-sea=polygons,extend-sea-sectors,close-gaps=1000,land-tag=natural=coastline family-id=111 product-id=1 family-name=Map1 draw-priority=20 transparent=no mapname=10000001 input-file=coastline.osm style-file=/home/maning/routable_garmin/git/osmphgps/styles/outdoor family-id=222 product-id=1 family-name=Map2 draw-priority=25 transparent=yes mapname=20000001 input-file=elev_level.osm style-file=/home/maning/routable_garmin/git/osmphgps/styles/outdoor family-id=333 product-id=1 family-name=Map3 draw-priority=28 transparent=yes mapname=30000001 input-file=pois_lines.osm style-file=/home/maning/routable_garmin/git/osmphgps/styles/outdoor ========== But I get this error: time java -jar mkgmap.jar --read-config=args0.list java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.ArrayList.rangeCheck(ArrayList.java:571) at java.util.ArrayList.get(ArrayList.java:349) at uk.me.parabola.mkgmap.reader.osm.SeaGenerator.joinWays(SeaGenerator.java:209) at uk.me.parabola.mkgmap.reader.osm.SeaGenerator.end(SeaGenerator.java:265) at uk.me.parabola.mkgmap.reader.osm.OsmReadingHooksChain.end(OsmReadingHooksChain.java:78) at uk.me.parabola.mkgmap.reader.osm.xml.Osm5MapDataSource.load(Osm5MapDataSource.java:73) at uk.me.parabola.mkgmap.main.MapMaker.loadFromFile(MapMaker.java:148) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:58) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:224) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:221) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:636) I also tried creating the maps separately and then run another mkgmap instance, but I don't see the coastline and hillshade: time java -jar mkgmap.jar --gmapsupp --product-id=1 --family-id=111 --draw-priority=20 10000001.img COASTLINE.TYP --family-id=222 --transparent --draw-priority=25 20000001.img ELEV.TYP --family-id=333 --transparent --draw-priority=28 30000001.img The typ files have the different FID for each layer. -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------
