I create foot routable (but not vehicle routable) ways around car parks in my style (I don't use the default style). This allows pedestrian routing around the car park in cases like https://www.openstreetmap.org/directions?engine=graphhopper_foot&route=42.45 938%2C-71.35133%3B42.45856%2C-71.35058 which is a few yards away from the previous example. It is common for footpaths to start at the edge of a car park and in my opinion it is incorrect to add to OSM a non-existent footpath across a car park purely for the purposes of routing.

What I meant is that foot routes like this are found https://www.openstreetmap.org/directions?engine=graphhopper_foot&route=42.46 043%2C-71.35108%3B42.46162%2C-71.34935 but that's a case of correct OSM data, as it should be. I think Ticker is saying that sometimes the footpath is joined to the amenity=parking polygon, instead of the service road, and correct routing does not magically jump over that gap. _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
