Tools to convert [openstreetmap.org OSM maps] to Garmin maps. Modified to get it building with maven.
Build both mkgmap and splitter with mvn clean package
The original, manuals other versions etc are on https://svn.mkgmap.org.uk/mkgmap/mkgmap. There is a github copy on https://github.com/openstreetmap/mkgmap
See the doc directories, readme and licence files in the modules for more details.
This example walkthrough shows how to compile an OSM map of your choice. It is assumed you have java8 sdk, maven, git installed already. This walkthrough assumes you want to use the "grey" style. Substitute "grey" with the style of your choice.
- Download this project
- cd osm-garmin
- mvn clean package
- download a YOURCOUNTRY pbf file from https://download.geofabrik.de to the working directory (root of osm-garmin)
- mkdir work
java -jar splitter/target/splitter-412-jar-with-dependencies.jar --output-dir=work YOURCOUNTRY.osm.pbfjava -jar mkgmap/target/mkgmap-4855-jar-with-dependencies.jar --family-id=35 --output-dir=work stylefiles/grey/style/typ/grey.txt work/*.pbfjava -jar mkgmap/target/mkgmap-4855-jar-with-dependencies.jar --output-dir=work -c stylefiles/grey/grey_options --style-file=stylefiles/grey/style/grey work/*.pbf stylefiles/grey/style/typ/grey.typ
In command 8, the map will be built without sea. To incorporate sea in your final map if needed, you need to download the latest sea information as well and replace command 8 :
- go to https://www.mkgmap.org.uk/download/mkgmap.html and download the latest-sea.zip to your current directory
java -jar mkgmap/target/mkgmap-4855-jar-with-dependencies.jar --output-dir=work -c stylefiles/grey/grey_options --style-file=stylefiles/grey/style/grey/ --precomp-sea=sea-latest.zip work/*.pbf stylefiles/grey/style/typ/grey.typ
Now a gmapsupp.img should be in your work dir, ready to be copied to the Garmin.
NOTE1 if you put multiple maps generated this way on your garmin, only one may show up. I think this is due to the name or id of the generated maps to be equal, causing a conflict.
NOTE2 Since 2022, to use the converted maps you seem to need software rev 9.2.9 on the Garmin Edge. Maybe some earlier versions work as well but 7.10 seems not, and most (or all) of the map will be invisible. The only explanation I can think of is that since early 2022 the OSM maps contain some new information. The new information seems correctly translated by this converter, but the older Edge software can not handle it.
