[mkgmap-dev] Error - zero length arc

Sun Jul 26 23:30:35 BST 2009

I have a problem with a zero length arc (mkgmap 1107):

SCHWERWIEGEND (RoadNetwork): Road null (OSM id 34881225) contains zero
length arc
SCHWERWIEGEND (RoadNetwork):
http://www.openstreetmap.org/?lat=47.83413&lon=11.70958&zoom=17

This is a strange railway=platform. It is mapped like a very narrow 'area'.
I have set the flag --remove-short-arcs and this road is also not on a tile
border. (I tried the same area with mkgmap 1092 and the map was created
without an error message.)

Is there a problem with the remove-short-arcs algorithm?
(I can change the OSM data but I'd prefer to have an mkgmap version without
error message for this kind of way).

Regards,
Rudi
