[mkgmap-dev] Routing problem on cut between maps

Thu Aug 23 13:04:27 BST 2012

I am having problems with the following intersection between the N402 and the N201 on my generated map:

http://www.openstreetmap.org/?lat=52.22506&lon=5.01017&zoom=16

The problem occurs on the N201 at the point where the two one-way roads merge again, just to the west of the intersection. Eastbound, there is no problem. Westbound, the generated map won't let me route past the point where the roads merge again. Problem occurs both in Mapsource and my GPS device (276C).

I split the map using the following two tiles, which cut the map just a couple of metres to the east of the merge point:

West tile (52.119140625,4.74609375) to (52.294921875,5.009765625)
East tile (52.119140625,5.009765625) to (52.294921875,5.361328125)

It looks like this adds a new merge point for the one-way roads on the cut between the tiles. As a result there are now two one-way streets exactly on top of each other between this new merge point and the original one. The routing software is apparently only using the eastbound one.

Software used: mkgmap 2311 and splitter r200
Used OSM data from Aug. 11

Hope I'm clear...
