BTW I found a style file work around to increase routing distance.
Where my map’s max was 1400km before I can now route up to 2200km, by simply upgrading the road-class of the major long distance connector roads.
I added the following to the lines stylefile after the line
highway=motorway {add oneway = yes; add bicycle = no; add foot = no } [0x01 road_class=4 road_speed=6 resolution 12]
*#handling specific long distance connector routes* *highway=trunk & (ref=N1|ref=N2|ref=N3|ref=N4) [0x02 road_class=4 road_speed=5 resolution 12]*
I would guess you would get even better routing using highway=motorway {add oneway = yes; add bicycle = no; add foot = no } [0x01 road_class=4 road_speed=7 resolution 12] *highway=trunk & (ref=N1|ref=N2|ref=N3|ref=N4) [0x02 road_class=4 road_speed=6 resolution 12] **highway=trunk [0x02 road_class=4 road_speed=5 resolution 12] I'ld actually go so far to put all road_class=4 and road_speed=7 - though then you're estimated arrival times will get a bit quick.. cGpsMapper manual should not be trusted regarding their proposals - best is trial and error but changing few variables at a time. *
Thanks. I'll try this out. The cGPSMapper manual contains the following fairly obscure statement:
...it is important to prepare data with non broken road network keeping specific road class...
This might be related to the reason for your longer routing distances.
Cheers. ------------------------------------------------------------------------
