[mkgmap-dev] Need some information about routing

Hi Manfred,

If you created the two maps from exactly the same input files and with the same options reg. routing I assume that this is caused by the differences in the two lines files. Can't say more without knowing the exact input data and options for mkgmap.

Betreff: [mkgmap-dev] Need some information about routing

Hi all

I've stumbeled about a small routing problem. I do create two types of
maps, one is called "myland" with nearly all informations to be found in
OSM, the other is called "mystreet" which do mainly show all streets but
less information about the surrounding. The two 'lines' files in the
appropriate styles are nearly same, except that for the street map all
the ways not suitable for automotive driving are not rendered.

My question is, using the same destination in either map, the routing is
slightly different in my Garmin 276Cx. For example, routing in the land
map uses some grade1 tracks within a forest, the street map does not.
But the tracks are  to be find in both maps. Anyone an idea, why this is
computed differently in the device ?
