Hi Carlos, and Minko, thanks for the quick feedback. Seems I've done something wrong. Maybe the calculation of the profile depends on the quality or density of the contour line data? I used existing contour data for Bremen, maybe the area is too flat ? I'll try again with different data.

When I have a map merged with contours but without DEM and without show-porfiles=1 in my options args file the elevation profile is greyes out and not available. Only if I use show-porfiles=1 an altitude profile is available when making a route. So please keep this option or make it default. ________________________________ Van: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> namens Carlos Dávila <cdavilam@orangecorreo.es> Verzonden: donderdag 11 januari 2018 00:14:29 Aan: mkgmap-dev@lists.mkgmap.org.uk Onderwerp: Re: [mkgmap-dev] option --show-profiles and DEM 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. El 11/01/18 a las 09:03, Gerd Petermann escribió:
Hi all,
the help says --show-profiles=1 Sets a flag in tdb file which marks set mapset as having contour lines and allows showing profile in MapSource. Default is 0 which means disabled.
I've tried this with MapSource. My findings: The option is not related to contour lines, those are always displayed and height is shown when you select one. I found two effects of show-profiles=1: 1) The button "Show Profile..." in the Route Properties popup is enabled even if no DEM data is available. Without DEM data this button is of no use, the displayed profile is a straight line at height 0. 2) With DEM data available Mapsource displays the height in the status line when you hover over a hill-shaded area with valid data.
The button "Show Profile..." in the Route Properties popup is always enabled when DEM data is available.
My conclusion: The option is useless without DEM data and with DEM data it should default to --show-profiles=1
In other words: I think the option should be removed and the flag should be set depending on the DEM data.
