[PATCH v1] Improving internal contour lines generation
by Ronny Klier 22 Feb '10

22 Feb '10

This patch adds support for maps crossing borders of SRTM (hgt) files. So its possible to create contour lines for larger areas. Additional: - description of contour relevant options - "dem-increment" option has been modified so it is possible to create different contour levels (major, medium, minor) Open issues: - I am still struggling with using multiple GeoTiff files (CGIAR + ASTER). - data files have to be loaded manually.

Commit: r1583: Separate out building the overview map from building the
by svn commit 22 Feb '10

22 Feb '10

Version 1583 was commited by steve on 2010-02-22 23:08:18 +0000 (Mon, 22 Feb 2010) BRANCH: overview Separate out building the overview map from building the tdb file. They are still a little related as the overview map is used to fill in a couple of details of the TDB. The overview map must be done first for this reason.

Multipolygon artificial tagging
by WanMil 22 Feb '10

22 Feb '10

Hi Marko and others, the patch for the mp code does not remove any tags from the source polygons and lines. Instead it tags all mp-source lines and polygons with mkgmap:mp_source=yes. All artificially created polygons during the mp processing are tagged with mkgmap:mp_created=yes. Example: Polygon A - natural=water, role=outer Polygon B - landuse=grass, role=inner Result after mp processing Polygon A - natural=water, role=outer, mkgmap:mp_source=yes Polygon B - landuse=grass, role=inner, mkgmap:mp_source=yes Polygon A1 - natural=water, mkgmap:mp_created=yes Polygon A2 - natural=water, mkgmap:mp_created=yes Polygon B1 - landuse=grass, mkgmap:mp_created=yes Maybe you could play a bit with this and post any new ideas how to improve the tag handling in the mp code.

Process for Creating Contour Maps?
by Jeffrey Ollie 22 Feb '10

22 Feb '10

Does someone have wiki pages describing the best procedure to create contour maps for Garmins? It seems like a number of people are having some success but it doesn't seem to be very well documented. I'm working though trying to get groundtruth to generate .osm files with contours in them and then using mkgmap to create an .img file but mkgmap is segfaulting. In any case though, I'd like to get contour maps using better data than the STRM that groundtruth uses. My ultimate goal is to generate contour maps for a trip out to the Grand Canyon this summer. -- Jeff Ollie

Version 1581 was commited by marko on 2010-02-20 21:35:50 +0000 (Sat, 20 Feb 2010) Move leisure=sports_centre below sport=* so that it will only be used when no matching sport=* is specified.

DEM subfile
by Christian Gawron 21 Feb '10

21 Feb '10

Hi, based on some freely(?) available maps with DEM data and on "empty" DEM files created by GMapTool I started to analyze the DEM subfile format. With the little information I got so far (see http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/DEM_Subfile_Format) I managed to write some rudimentary code to create empty DEM files with mkgmap (just the same as GMapTool can do). If anybody has more information on the DEM format, I would be very happy to hear about it. Best wishes Christian

access restrictions and routing
by Torsten Leistikow 21 Feb '10

21 Feb '10

Moin, I am trying to restrict the access to some streets during the routing, but I can't get it working. I have a rule in my style file like: highway=* & mkgmap_routing=foot {set motor_vehicle=no} [0x09 road_class=1 road=speed=1 resolution 22] I want the street only to be used for routing, when the routing mode is set to food. But right now mapsource is using the streets also in car/motorbike routing. Is there a mkgmap-switch (version 1575) required, if I want to use the access restrictions? Gruss Torsten

Please help: --generate-sea: No coastline
by Daniela Duerbeck 21 Feb '10

21 Feb '10

Hi! I am relatively new to mkgmap but I searched the archive and found no answers. So I try to find help in this mailing list. I know that generate-sea is still buggy but I cannot achieve any blue sea. I try to generate a routable map of the Canary Islands. With the mkgmap version 1580 I do not even get the coast lines. With 1484 I got blue islands on yellow sea. Can there be any interaction between style-files and the generate-sea option? I used these style files: http://dev.openstreetmap.de/aio/styles/styles.tar.bz2 The latest splitter.jar. and the needed files from this tarball I copied into the directory, where I then ran this script: -------------------------- wget http://www.informationfreeway.org/api/0.6/map?bbox=-18.55,27.29,-12.82,29.89 -O canarias.osm mkdir tiles cp splitter.jar tiles cd tiles $JAVA_BINDIR/java -Xmx2000M -jar splitter.jar --mapid=63240347 --max-nodes=1000000 ../canarias.osm cd .. mkdir gbasemap; mkdir gaddr; mkdir gboundary cp mkgmap.jar gbasemap; cp mkgmap.jar gaddr; cp mkgmap.jar gboundary; cp -r addresslayer_style gaddr cp -r boundary_style gboundary cp -r masterstyle gbasemap cp -r addr.TYP gaddr cp -r boundary.TYP gboundary cp -r master.TYP gbasemap cd gbasemap $JAVA_BINDIR/java -Xmx2000M -jar mkgmap.jar --max-jobs --style-file=masterstyle --description='Openstreetmap' --country-name=spain --country-abbr=ES --family-id=4 --product-id=45 --series-name='OSM-AllInOne-ES-bmap' --family-name=OSM --area-name=EU --latin1 --mapname=63240345 --draw-priority=10 --add-pois-to-areas --make-all-cycleways --link-pois-to-ways --remove-short-arcs --net --route --ignore-osm-bounds --generate-sea='polygons' --gmapsupp ../tiles/*.osm.gz master.TYP cd .. cd gaddr $JAVA_BINDIR/java -Xmx2000M -jar mkgmap.jar --max-jobs --style-file=addresslayer_style --description='Adressen' --country-name=spain --country-abbr=ES --family-id=5 --product-id=40 --series-name='OSM-AllInOne-ES-Addr' --family-name=ADRESSEN --area-name=EU --latin1 --mapname=63241345 --draw-priority=20 --no-poi-address --no-sorted-roads --add-pois-to-areas --transparent --gmapsupp ../tiles/*.osm.gz addr.TYP cd .. cd gboundary $JAVA_BINDIR/java -Xmx2000M -jar mkgmap.jar --max-jobs --style-file=boundary_style --description='Boundary_Layer' --country-name=spain --country-abbr=ES --family-id=6 --product-id=30 --series-name='OSM-AllInOne-ES-boundary' --family-name=boundary --area-name=EU --latin1 --mapname=63240625 --draw-priority=21 --no-poi-address --no-sorted-roads --transparent --gmapsupp ../tiles/*.osm.gz boundary.TYP cd .. ./gmt -jo gmapsupp.img gbasemap/gmapsupp.img gaddr/gmapsupp.img gboundary/gmapsupp.img ----------------- Are there any additional options I should try to get at least a buggy sea?

Re: [mkgmap-dev] Commit: r1576: There seems to be a way to show elevation profiles
by Minko 20 Feb '10

20 Feb '10

Hi, I use the standard Garmin types for contour lines, 0x20, 0x21 and 0x22 I created the contour lines with Srtm2Osm, split srtm.osm data with the same tile area bounds as my map. Now I have two img's of the same area, one with osm data, one with contour lines. E.g. 10010001.img and 10010101.img The contour tile is transparent so I can see the contours on top of the map in Mapsource. Is it possible to merge those two layers into one tile and still keep the routing? How can I merge the two 10010001.osm with 10010101.osm or 10010001.img with 10010101.img? Will it be possible to show the elevation profile with this approach? Cheers, Minko Ronny Klier wrote: This will not work. I got the same problem in different versions of MapSource. May be there should be an explicit warning in "show-profiles" option help. > > If I make one mapset with only contour lines, I see an emtpy profile. > This works fine for me (in 6.15.11). Did you use the standard Garmin types for elevation(0x20-0x21)?
