Make maps for Garmin devices

This git is what I use to make maps for my Garmin devices.

To make your own maps you need to:

  1. Make sure your Linux installation has all the required dependencies. (See below.)
  2. Clone this git.
  3. Download the latest version of mkgmap and splitter from the mkgmap homepage.
  4. Run make.sh to download some other stuff needed and create some folders.
  5. Download the osm.pbf file you want to make a map from on the Geofabric website.

When all this is done you can make the maps.

  1. Run "split-map" to use the splitter to make smaller files from your main file.
  2. Run "make-map" to make the map from the files above.

When this is done you have a file "gmapsupp.img" in the output-map folder that you can copy into your Garmin device.

Prerequisites (dependencies)

You need to have a version of java >= 1.8 on computer. And unzip.

Command line options

There are not many options you can change from the command line. The only place changes are allowed is when running "split-map" so you can choose

  1. what .pbf file you want to work on if you have several. (By default the largest file is chosen.)
  2. specify a polygon file if you only want to make a map from a subset of the .pbf file.
PBF=norway.osm.pbf POLY=no-se.poly ./split-map
