[mkgmap-dev] mkgmap r4025 implements --x-dem-poly option

Fri Jan 5 08:54:13 GMT 2018

Hi Carlos,

I am now trying to use your options. 
Maybe you use different options for splitter, with my options I have to use --block-size=2048 to avoid MapFailedException.
Please post the split-file created by splitter (areas.list).
Up to now I've tested with -Xmx6G and I think the value 2500m looks too low.
So, my 2nd suggestion is to try with a higher value.

Gerd

Hi Gerd
I also use hgt files from viewfinderpanoramas. I split bolivia with
max-nodes=100000 and then run mkgmap as follows:
java -Xmx2500m -ea -Dlog.config=logging.properties -jar mkgmap-dem.jar
--block-size=1024 --x-dem=../DEM/hgt --x-dem-poly=polygons/bolivia.poly
--x-dem-dists=3312,5846,8948,12646,20282 --x-overview-dem-dist=128000
--gmapi --show-profiles=1 --output-dir=../mapas/$pais
--bounds=bounds.zip --precomp-sea=sea.zip --max-jobs=1 --route --latin1
--code-page=1252 --country-name=$PAIS --country-abbr=$ABR
--area-name=$MAPA --family-name="OpenStreetMap $MAPA" --family-id=1$FID
--product-id=1 --product-version=$VERSION --series-name="OSM-$MAPA"
--overview-mapname=$ABR-1${FID} --overview-mapnumber=551${FID}000
--name-tag-list=$NAMETAG --index --process-destination --process-exits
--housenumbers --reduce-point-density=4 --polygon-size-limits="24:12,
18:10, 16:0" --add-pois-to-areas --link-pois-to-ways
--location-autofill=is_in,nearest --drive-on=detect,$DRIVEON
--license-file=license_ODbL.txt --copyright-message="OpenStreetMap
contributors, ODbL. See: http://www.openstreetmap.org/copyright"
$LANGUAGE --road-name-config=$CONFIG
--x-mdr7-del=GRADE0,GRADE1,GRADE2,GRADE3,GRADE4,GRADE5,GRADE6,GRADE7,UNNAMED
--remove-ovm-work-files=true --style-file=../resources/styles
--style=mio --check-styles -c $pais.args

Tomorrow I'll try with default style, just to see if it makes any difference
