[mkgmap-dev] [Patch v2] sharp angles

Thu Sep 3 09:25:50 BST 2015

Hi Gerd - okay now with patched and removing --adjust-turn-headinfs - plus
adding both options I can see (vs before with adjust-turns-headings)
a) improvements on some tight turns (though not all tight turns)
b) less of those errors (though some still exist - but much less)
c) less erroneous detours on longer routes
d) valid only for Car/Motorcycle routing - often on the same route shorter
times - sometimes longer as well though. The other profiles are much less
affected here.

e) no difference at all in the maximum routable distance.

Once a strange degradation (again same place as yesterday):
Routing is alway correct on old map - but times are much slower. Old map
nearly always had 1min

Only on Driving profile this bug happens (but no other - even Motorcycle is
fine). Still 1min. However all other profiles (except walking) are between
26-28seconds.

Overall I would say it's a clear improvement (but yeah - those additional
ways I guess would still be better).
