[mkgmap-dev] default style improvements

From Ticker Berkin rwb-mkgmap at jagit.co.uk on Tue Dec 4 16:50:45 GMT 2018

Hi Gerd

I had various OSM maps for Great Britain, Spain, Italy, Belgium and
Morocco of different ages and when I found a highway tag that wasn't
handled, looked at a few examples of the way/relation on OSM.

For trail, I don't think I found many examples and 'track' seemed a
reasonable option because, the example I looked at:


joined to 2 other 'track's. 'path' is probably better but that there is
logic to convert 'path' to footway/cycleway/bridleway.

The rest_area example I looked at didn't have any other highway into
it, just a closed highway=rest_area with the beginning and end along
the main highway. It seemed best to make it routable so that navigation
turns into it correctly, rather than it saying a 90 degrees turn to the
center, after having gone past the entrance.

One of the maps I used was about 6 months old, and lots of the examples
of bad tagging I went looking for, I found you'd recently fixed in OSM.
