[mkgmap-dev] [Patch v3] sharp angles

Sat Sep 5 12:18:37 BST 2015

Well - I guess this will never be without errors - with Patch v3 there 
is again a little loop - now again at the first place:

(only happens with "Shorter Distance" and one of the 
driving/motorcycle/Dirtbike and so on profiles..).

Also on some other places still detours - in general "Shorter Distance" 
seems to be much more problematic than "faster time". So for sharp turns 
- ironically - shorter distance chooses the detour to avoid the sharp turn.

I'm not really sure patch v3 is better than v2 however. Results are 
50/50 better/worse. However the arrival times got a bit slower (even if 
following exactly the same route). I always tried with --x-cycle-map 
switch - never without. I'm still not so sure what this option really 
changes for outcome in the end.
So - additional intersection roads would still be king IMHO... (but yes 
I know - not possible).
