[mkgmap-dev] option --show-profiles and DEM

Thu Jan 11 08:14:29 GMT 2018

If you compile a map with contour lines and show-profiles=1 MapSource 
does calculate route profile. I've been using a command like the 
following for a long time and it worked for me:
java -ea -Xmx4500M -jar mkgmap.jar --output-dir=./tmp --tdbfile --latin1 
--code-page=1252 --description="OSM+$CURVAS-$MAPA" --country-name=$PAIS 
--country-abbr=$ABR --family-name="OSM+$CURVAS $MAPA" --family-id=3$FID 
--product-id=1 --product-version=$VERSION --series-name="OSM+$CURVAS 
$MAPA" --area-name="$MAPA" --overview-mapname=$ABR-3$FID 
--overview-mapnumber=653${FID}000 --index --road-name-config=$CONFIG 
--show-profiles=1 tmp/551${FID}*.img curvas/602${FID}*.img 
typ/$ABR-3${FID}.TYP
Where tmp/551${FID}*.img are precompiled regular map tiles and 
curvas/602${FID}*.img are precompiled contour lines tiles. The only 
issue is MapSource doesn't display contour lines, only height numbers.
