[mkgmap-dev] Routing problem

Mon May 11 20:38:07 BST 2009

Hi.

I am using the map from
http://openstreetmap.teddynetz.de/latest/de_rout_gmapsupp.img.gz

that has been generated by mkgmap war Version 1024 with

$JAVA -jar $BASE/$MKGMAP --family-id=42 --style-file=$BASE/teddy
--road-name-pois --add-pois-to-areas --location-autofill=2
--country-name=Deutschland --country-abbr=DE --gmapsupp
 --latin1 --net --route $BASE/rout/*.osm.gz $BASE/teddy.TYP

I find that the routing for pedestrians gets very crappy on longer
distances (> 10 km) and tends to use large roads. As an example when
cycling from 

http://www.openstreetmap.org/?lat=50.93348&lon=6.78133&zoom=17&layers=0B00FFF

to

http://www.openstreetmap.org/?lat=50.93348&lon=6.78133&zoom=17&layers=0B00FFF

is nonsense until I cross this point (the same in both directions):

http://www.openstreetmap.org/?lat=50.93348&lon=6.78133&zoom=17&layers=0B00FFF

After that the route is really good. Any hints on what might be going
wrong?

Sincerely,
Joachim
