Hi, I have been compiling my own maps of my local areas (<600 mB) for a couple of years now but the other day for the first time I had to use splitter to divide a large .osm file. It took several tries to get everything working to the point that a useful map emerged from the process. However, my directives are not being processed so the map I get is a plain vanilla version The sea and coastline are invisible in the finished product. In addition, some of my custom lines are missing, for example, the ones used for unpaved roads and waterway direction. Inexplicably, most of my custom styles for both highways and POIs are visible. Th simple splitter command line I'm using is here: [code]java -Xmx1000m -jar ..\splitter\splitter.jar "C:\Users\alask\Downloads\Maps\Alaska.osm" --output-dir=..\splitter > ..\splitter\splitter.log [/code] I've seen examples of a splitter command that uses the *--precomp-sea="C:\Users\alask\Downloads\Maps\sea.zip" *argument in its call but iI tried that and it made no difference in the result. Anyway, this generates three .osm files (63240001, 2, and 3) which I then process with mkgmap and the following command line. This exact comand line (but without the template.args parameter) runs perfectly and creates a map containing all my styles and shows the coastline and sea properly: java -Xmx1000m -jar mkgmap.jar *-c "C:\Users\Alask\Documents\splitter\template.args"* --latin1 --family-id=24983 --name-tag-list=name:en,int_name,name --gmapsupp --description="Alaska" --country-name=USA --country-abbr=USA --index --location-autofill="is_in,nearest" --copyright-message="ODbL by OSM contributors" --link-pois-to-ways --add-pois-to-areas --reduce-point-density=4 --reduce-point-density-polygon=8 --merge-lines --route --drive-on=right --net --housenumbers --x-split-name-index --check-roundabouts --check-roundabout-flares --process-destination --process-exits --poi-address *--generate-sea=land-tag=natural=background --style-file="C:\Users\alask\Dropbox\Mapping\DJS_styles" --precomp-sea="C:\Users\alask\Downloads\Maps\sea.zip" --bounds="C:\Users\alask\Downloads\Maps\bounds" "C:\Users\alask\Dropbox\Mapping\24983djs.TYP"* Is the placement or order of the arguments important? Any other ideas or suggestions much appreciated. Thanks for your help, Dave -- Dave Swarthout Homer, Alaska Chiang Mai, Thailand Travel Blog at http://dswarthout.blogspot.com
