Mkgmap is a command line utility that converts OpenStreetMap data into vector maps that can be loaded onto a Garmin GPS device. It does the conversion in one step without depending on any other program. Mkgmap only supports the OSM map data format.

Get the latest version from the mkgmap download page. To see what has changed recently see the mkgmap news page.

Warning for Ubuntu / Debian / Other linux distributions

Some linux distros package mkgmap. Be aware that the packaged version often is very old though. You will be better off using one of the versions linked to above. If you experience problems, do yourself a favour and check the version.

Creating a map

Creating a map consists of several steps.

  1. Download OSM data
  2. Split the OSM data into tile using the tile splitter
  3. Create your own map style files (optional)
  4. Compile the tiles with mkgmap
  5. Upload the map to your GPS

Command line options

There are several mkgmap options to configure the details of how mkgmap creates the map. For a complete list see the complete option list (which may be outdated) or run

java -jar mkgmap.jar --help

There are some scripts for Unix users which might be helpful: Python Script.


OSM Map Composer for Windows provides a graphical interface with mkgmap (along with other components) running behind the scenes, thus eliminating the need to deal with the command line.
