Re: [mkgmap-dev] routing between different maps
Hi Henning, reg. performance: I think it is now clearly less then 1 s per tile for level 2 boundaries. reg. option: I see two ways to control this: 1) style rules may set a special tag mkgmap:xyz on those lines which should be considered as boundaries. I have no idea how to name such a tag, and user would need some rules in style files relations and lines / polygons. 2) an option like --add-boundary-nodes-at-admin-boundary=[level] The level parameter would default to 2, if e.g. 4 is given, all boundaries with levels <= 4 would be used. In both cases you can add your individual poly to the OSM data, e.g. a way with tags boundary=administrative ,admin_level=2 , and render=no and check the render tag in the style so that the way is not added to the map. I think I'll implement 2) now, looks like the safer way to me. Gerd Von: mkgmap-dev im Auftrag von Henning Scholland Gesendet: Freitag, 27.

Re: [mkgmap-dev] routing between different maps
Hi Gerd, in my opinion this is valuable change and should be merged to trunk. I would even suggest to use admin level 2 as default. This would lead to compatibility between maps, even if authors are unaware of this feature. -- Best regards, Andrzej ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] routing between different maps
Hi Andrzej, okay, seems there are many ways to test this ;-) I've created the routes in MapSource and transferred them to the Oregon. Next, I looked at them in the Route Manager. With other routes, when I select button "Map" in the Route Manager the route is also first displayed as a straight line and then recalculated. Only with these map crossing ways I don't see a recalculation. Interesting is that I see recalculation when I select a different default route vehicle, but the results look bad. Anyway, I think the extra nodes can improve routing, so I'll add an option to specify the admin_level. Gerd Von: mkgmap-dev im Auftrag von Andrzej Popowski Gesendet: Donnerstag, 26.

Hi Andrzej, I also used car and no avoidances. Maybe the difference is that I used mkgmap to create different gmapsupp files.

Re: [mkgmap-dev] routing between different maps
Hi Gerd, haven't tried it, but would be surprised if it's supported as it is not the Garmin way... They want you to send all the map tiles by Garmin software to the GPS. But if this can work with mkgmap it's another step. Now we need the non-rectangular tiles...

Hi Andrzej, I think the code in the branch (r4211) works quite well now, performance is okay and the number of added external nodes looks reasonable. next on my TODO list: 1) Find good option name and document it. Current code always uses admin_level=2 boundaries. If one splits each German Bundesland and user tries to install e.g. Niedersachsen and Schleswig-Holstein this will not help. So, as you proposed, we might want an option that works like this: --add-ext-nodes-at-borders=x The value x specifies the admin_level. This option tells mkgmap to add so called external routing nodes (NOD3 and NOD4) where roads intersect with boundaries of the given admin_level.

Re: [mkgmap-dev] routing between different maps
Hi all, I've started to look at this. My approach so far: - add a new flag "on-country-border" in the Coord class - collect ways with admin_level=2 contained in the input file (alternative would be to extract them from the bounds file), also way members of matching boundary rels - split those ways into two point segments, so that no segment exists twice - for each road segment calculate the intersection with any of these segments (a spatial index is probably needed), brute force might be too slow - if one is found, either add the intersection node or mark one of the existing nodes if it is very close - make sure that these special nodes are preserved like other boundary nodes - make sure that they are added to the list of external nodes I am not yet sure what to do with roads that share multiple nodes with country borders.

Re: [mkgmap-dev] routing between different maps
Hi Andrzej, I doubt that it is possible. The extracts from Geofabrik overlap at the administrative borders. So a road from e.g. Germany to Poland won't end at the border, but extend a few meters (sometimes even kilometers!) into the neighboring country. And that holds true for that road in the other direction too. This means that the common nodes do already exist, but never did cross-border routing work (note that I changed my toolchain and generate maps containing a few countries because of those issues since a couple of years - I cannot be sure if things have changed meanwhile). Or did I misunderstand the "external nodes"? Kind regards, Bernhard ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
