Re: [mkgmap-dev] Indexing street belonging to two cities
Hi Piotr, this probem exists probably around the world. Some mappers split OSM ways at boundaries to solve this. Anyway, there is no easy way to solve this in mkgmap. It would be possible to split all OSM ways with highway=* at boundaries before style processing, so that each part gets different mkgmap:admin_level=* values and thus different mkgmap:city values. When --bounds is used the needed data should be available. Disadvantage would be that the number of road objects in the *.img file increases although we can store multiple cities for one road. Another simpler approach could be to post process just the way nodes for those ways which are routable (after style processing). This is probably easier to implement and closer to the way how housenumbers are processed, but still a lot of work. Why does it work with house numbers? Because each node or way with addr:housenumber is processed by the style rules and thus different numbers may have different mkgmap:city values. The program collects those values in a list for each road object when the housenumbers are processed. Without housenumbers there is only the information from the road object itself.

If there are addresses, mkgmap can deal with that problem and allow garmin devices to find the proper address. But if there are no addresses, I was not able to find a method for proper search index generation. Is there any solution for this problem? cgpsmapper supports this type of indexing by using @ in cities name: CityName=city1@city2 so img format can handle this.

Hi Gerd, So if I understood correctly it is mainly a data problem not a compiler problem itself. I am using mkgmap for compiling mp files, so streets location is clear. As I said cgpsmapper supports this type of street sharing using @ within cityname. Presently I am compiling source with cgpsmapper, but I would like to use mkgmap for this purpose, as for new Garmin receivers there are better voice commands (especially keep right/left works as it should). I know that mkgmap is mainly for osm sources, but do you think it would be possible add this feature for mp files?

Hi Piotr, yes, with *.mp files this should be easier. Please provide a sample input and desccribe the expected result and also attach the output from cgpsmapper.

What is enough for you, just an img file, or all files required by Mapsource/Basecamp? Additionally, cgpsmapper will also include data for [SIGN] sections that allows to control what is printed on the top bar of garmin devices (eg, Exit 2 toward XXX). I wonder how difficult would it be to support this feature as well. Piotr ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk https://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
