[mkgmap-dev] coastline boundaries
Hi, How can I filter out all lines wich are part of boundaries that have a natural=coastline tag? For instance this way: http://www.openstreetmap.org/way/39862450 On my map I dont want to see the boundary lines along the coastlines, but in the style files I can't filter boundary=administrative & natural!=coastline. Somehow administrative boundaries are processed without the coastline tags. Or can I use osmfilter to delete all ways that are tagged with natural=coastline AND are part of a boundary relation? ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] coastline boundaries
Anyone who can explain this behaviour? Are the tags on ways copied to boundary lines or are the boundaries treated independently?

Re: [mkgmap-dev] coastline boundaries
Hi Minko, I am not sure if I can help here. You use the precomp-sea option, that means that ways with natural=coastline are filtered in this way: a) the tag natural=coastline is removed from the original way b) a copy of the way with the same points is created. This new way has a Fake-Id like 4611686018427387908 and the tags natural=coastline,mkgmap:stylefilter=polyline This happens before style processing. Iam not sure why this is done.

Thanks Gerd, that explains it. > I am not sure if I can help here. > You use the precomp-sea option, that means that ways with > natural=coastline are filtered in > this way: > a) the tag natural=coastline is removed from the original way A better option would be to rename this tag into mkgmap:coastline=yes (or some other tag) instead of deleting natural=coastline so I can filter all boundaries from those ways > b) a copy of the way with the same points is created. > This new way has a Fake-Id like 4611686018427387908 and the tags > natural=coastline,mkgmap:stylefilter=polyline Thats ok with me, I dont render natural=coastline > This happens before style processing.

Re: [mkgmap-dev] coastline boundaries
Developers, Is it possible to give a mkgmap:coastline=yes (or some other) tag to those boundaries where the coastline has been (re)moved?

Hi Minko, I discussed that with WanMil in a pm. I'll post a patch today.

Re: [mkgmap-dev] coastline boundaries
Hi Minko, attached is a patch (works with trunk and high-prec-coord branch). In combination with precomp-sea option ways with natural=coastline are kept as is, but they are only processed by the lines rules. A compiled binary (branch version) is here: http://files.mkgmap.org.uk/download/177/mkgmap.jar Please note that this contains many changes regarding routing, so please use with care.

Re: [mkgmap-dev] coastline boundaries
Hi Gerd, Patch works as expected, I am able to clean-up the boundary coastlines now, thanks! Regarding routing, it solves a much bigger issue: this patch seems to solve the broken routing at the tile borders too (pedestrians, other vehicles with motorways avoidance selected). So this is a very promising improvement! > attached is a patch (works with trunk and high-prec-coord branch). > In combination with precomp-sea option > ways with natural=coastline > are kept as is, but they are only processed by the lines rules. > > A compiled binary (branch version) is here: > http://files.mkgmap.org.uk/download/177/mkgmap.jar > > Please note that this contains many changes regarding routing, so > please use with care. ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] coastline boundaries
Hi Minko, great! Just to make that clear: the patch is not related to routing, the routing changes were done from r3026 to r3036, and there is still more to do as NodCheck still reports thousands of (similar) errors...

Re: [mkgmap-dev] coastline boundaries
Hi Gerd, I don't know what you discussed with WanMil, but I think it would be better to use mkgmap:coastline=yes in combination with precompiled sea polygons and keep the original way completly untouched (as you did already). In this case no special handling for natural=coastline is necessary. Such a special handling isn't easy to understand. While processing mkgmap has to decide, if precompliled data should be used or original data. If precompiled data is used, mkgmap is using mkgmap:coastline=yes for generation, otherwise natural=coastline is used.

Re: [mkgmap-dev] coastline boundaries
Hi Henning, I am not sure what you mean. Where would the tag mkgmap:coastline be used? Do you mean that the precompiled sea data should be passed to the style with this tag?

Re: [mkgmap-dev] coastline boundaries
Hi Gerd, processing the precompiled data through style isn't necessary. But I would leave it to the style-dev to take care about rendering natural=coastline also in polygon-file or not. After thinking some minutes more, my approach isn't that better then yours, if you remove the ignore function for polygon-file.

Re: [mkgmap-dev] coastline boundaries
Hi Henning, okay, first a correction : precompiled data is passed to the style (polygons), tags are natural=sea or natural=land (or the tag configured with --land-tag) If we also pass the osm data, we will have duplicate or heavily overlapping shapes, so I think it is a good idea to pass them only through the lines rules so that you can add coastlines, as this would not work with precompiled sea data. Another question is if that should also be done when option --coastlinefile is used, I don't know the content of such a file.
