About

• CoMaps router is homegrown, so no 3rd parties.
• It runs offline only within downloaded areas, except it uses the world map for big routes and ferries.

Something is not working?

• It could be you used car for walking, or something like that?
• It could be the OSM data - Verify that other routers in www.openstreetmap.org work, try: GraphHopper, OSMR, Valhalla.
  • If they perform similar, then it may be the OSM data, some restriction is missing or a road may not be connected. This is something a OSM volunteer may know. Feel free to report to us and/or the OSM community.
  • They perform too different than CoMaps, please:
    • Open an issue here.
      • Send us the routing from / to, preferrably in OSM equivalent like this example.
      • Make sure to specify the desired transport method and details.
      • Feel like keeping the route private, email us.

Conditional Routing

CoMaps has introduced a routing based on conditional restrictions

It includes:

• Basic time schedule condionals like: access:conditional=yes@23:00-05:00
• It applies only to ways but not yet to nodes. Currently there are nodes with this tags that get closed 24/7.

It doesn't include yet:

• Complex time schedule conditionals like : access:conditional=yes @ Dec 25

For the future
