Re: [mkgmap-dev] Translating route=bus relations

Done, with the apply_once keyword (see my previous message).
TO DO 2: add a 'points' file that appends the route names to
the names of bus/train/tram/subway stops, to translate role=*stop members.
Done, revised patch attached.
Next step: Combine the mkgmap --style=routes output with the
mkgmap --style=default output to a gmapsupp.img. I would really
appreciate help with that, in the form of a simple list of commands.
Best regards,

For what it is worth, here is what I tested so far. It results in a 1 MB
gmapsupp.img in 1 tile, while the normal Finland is over 40MB in 3 tiles.
Some local bus and train routes have been mapped, but no long-distance
services.
TO DO 1: filter duplicates. There can legitimately be duplicate way members
in route relations, because routes are best drawn as round-trip loops, if you
consider roundabouts (highway routes) or switch points (railways). For
rail routes, if there are multiple departure and arrival tracks on the end
stations, the most logical option would seem to include each set of tracks
in one roundtrip, something like this:
A1-...-B1-...-A2-...-B2-...-A3-...-B1-...A1
(notation: A,B=stations, A{1,2,3}, B{1,2} are tracks on the stations)
This would of course mean a lot of duplicates (e.g., T,T,T,T,T on the railway
line if the route=train carries ref=T). I think that this can best be solved
with a filter in the name rule.
TO DO 2: add a 'points' file that appends the route names to
the names of bus/train/tram/subway stops, to translate role=*stop members.

Marko

Would I have to invoke mkgmap multiple times, once for each map layer (family) and finally to combine the families to a single gmapsupp.img? Or can I ask mkgmap to generate multiple map families from the set of map tiles? What would be the best way to package translation rules for bus routes? If the route=bus layer is to be compiled separately from the base layer, then it would need a different style altogether, right? And I guess it could be compiled with fewer and bigger map tiles as well? Currently, my base layer of Finland is 3 tiles. I believe that one tile of bus routes would easily cover the entire country, at least until all bus routes have been mapped. I created a public transit layer for Toronto, Canada. Most of your suppositions are correct, at least the way I did it: - I had to invoke mkgmap once for each layer. Each layer had a different draw priority, TYP file, and mkgmap options (the public transit layer was transparent and not routable). - I did not use mkgmap to create the final gmapsupp.img file though. Instead I used Garmin tools (Roadtrip, MapSource) for this. (Some of the more recent changes to mkgmap's gmapsupp code may better support this now.) - I also created a completely new set of style files for the public transit layer. The style files were very basic, containing only items relevant to the public transit items (bus, tram, and subway stops, and the transit lines). - Since the information in the transit layer was so sparse, I also did not need to split the map into sub-tiles (I generated the layer from an entire map of Ontario, which otherwise needs to be split for the normal layer.) This should also most likely be the case for Finland. Does this help you? Cheers. ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
