Hi All, My first real test today of the routing on a Vista Cx and I can say you have all done a fantastic job getting this to work. It did highlight many roundabouts near home are not tagged correctly :( Peter...

Inter-Tile Routing for Maps with several tiles made from the same area
by Felix Hartmann 19 Feb '09

Great, routing across does not only work on tiles split with the osm-splitter, but also works if you produce tiles from the same are. I.e you can take austria.osm and use two different style-files one where the file "lines" includes motorways, trunk roads, primary roads and secondary roads, and another tile linking up all other roads. Routes can be calculated as if the roads were all on the same tile (at least in Mapsource - haven't yet tried on my etrex). This is with maps created directly from OSM without osm2mp. On the other hand autorouting does not seem to work if I try to route between a Point on Street A and a Point on Street B with the streets not being connected (in Austria very often due to the data import by plan.at streets are intersecting without having a connecting node - however often also streets are not connected due to user error), in this case the whole route will only be done as a straight line, instead of routing the main part and then only routing via "air" for the not connected parts. It would be great if there could be added an option to autoconnect highways before compiling. (I do understand that this will be not easy, but I don't think with the volatile format of OSM we can ever get really usable autorouting without adding some intelligent mechanism here)

Commit: r911: Fix ordering of NOD 3 entries near 0.
by svn commit 19 Feb '09

19 Feb '09

Version 911 was commited by robert on 2009-02-19 09:01:07 +0000 (Thu, 19 Feb 2009) Fix ordering of NOD 3 entries near 0. Was comparing coordinates in map units as unsigned values, now comparing degrees. This should fix inter-tile routing near longitude or latitude zero. Not sure what happens near longitude 180. Also move the comparison out of RouteNode into Coord.

Inaccuracy of point coordinates
by Paul Ortyl 19 Feb '09

19 Feb '09

Hi! I have noticed, that some ways, which are dead-straight, are not presented as such in MapSource and Garmin (etrex Vista HCx). It looks like the coordinates have lost its precision. Take a look at http://openstreetmap.org/?lat=48.899634&lon=8.718964&zoom=18&layers=B000FTF The "double" crossing of Blumenheckstraße and Körnerstraße makes the straight Blumenheckstraße being distorted on Garmin. These two points should be in line with the rest of the points on Blumenheckstraße, they are not in MapSource. Some other lines, which are supposed to be parallel (they are in josm and mapnik) look really weird in MapSource.
