Modified mkgmap's Subversion repository using mvn for build

OSM-Garmin

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.

Sample Walkthrough

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.

1. Download this project
2. cd osm-garmin
3. mvn clean package
4. download a YOURCOUNTRY pbf file from https://download.geofabrik.de to the working directory (root of osm-garmin)
5. mkdir work
6. java -jar splitter/target/splitter-412-jar-with-dependencies.jar --output-dir=work YOURCOUNTRY.osm.pbf
7. java -jar mkgmap/target/mkgmap-4855-jar-with-dependencies.jar --family-id=35 --output-dir=work stylefiles/grey/style/typ/grey.txt work/*.pbf
8. java -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 :

8. go to https://www.mkgmap.org.uk/download/mkgmap.html and download the latest-sea.zip to your current directory
9. 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.

osm-garmin's Issues

optimize "grey" style

There are a number of things to improve on this

• farmland is now grey. Maybe better use something yellow-brownish?
• Buildings now appear dark green. Better maybe something like grey or blueish
• space between houses now brown. Better make this grey
• Bike paths now are black lines. Need to be light grey or white
• There are dashed purple-black lines, need to change the purple color it's too bright for wat seems an irrelevant item (need to check what it really si)
• Why are there black lines along white roads. This reduces the visibility of the roads. Better leave out the black line and just have white line.
• Sea now looks grey

grey style zoomout

If you zoom out on the grey style to the 2km level or further out, all area becomes grey. No area seems rendered at all., as hovering over the grey area does not show any area name ("grass", "built-up area") as usual. The roads and water appear fine but I'd like to see some rough outlines of city shapes

bad roads

Some roads currently shown on the map as black lines are really bad roads, more tractor paths.
And therefore also are used by the garmin routeplanner.

For instance bridelways like this one
https://www.openstreetmap.org/query?lat=51.97435&lon=4.35932#map=19/51.97420/4.35928

The general label this road gets is "weg'.

Error in style

I get an error when I try to convert the /home/wouter/Desktop/test/cyprus-latest.osm.pbf

Just doing the standard conversion works

But when trying to apply the opentopomap style options I get

 java -jar mkgmap.jar -c opentopomap_options --style-file=style/opentopomap --generate-sea --output-dir=output 6324*.pbf style/typ/opentopomap.typ 
Time started: Fri Jan 28 20:25:07 CET 2022

This might also be an issue with the style file which I picked up from https://github.com/der-stefan/OpenTopoMap
I roughly did this

cd style/typ/
java -jar ../../mkgmap.jar --family-id=35 opentopomap.txt 
cd ../..
java -jar mkgmap.jar -c opentopomap_options --style-file=style/opentopomap --generate-sea --output-dir=output 6325*.pbf style/typ/opentopomap.typ
