[mkgmap-dev] [Patch v2] sharp angles

Thu Sep 3 06:03:23 BST 2015

Hi Felix,

got your mail with the pictures.
Please check:
You wrote that you used  --x-cycle-map, but you did not mention 
--x-fix-sharp-angles. I was probably not clear about these options.

If you did not also use --x-fix-sharp-angles you measured the effect
of the removal of the --adjust-turn-headings option, as --x-cycle-map
on it own has no effect with the patch.

Reg. testing: Please try to route to points close to but not on the road.
Maybe this avoids the u-turns when the Garmin algo reaches the target
on the "right" road (but "wrong" arc) and adds a u-turn to get on the road 
arc that was selected as target.

Well - I used 
--x-cycle-map

but for some intersections it would still not work. In 4 out of 10 long distance routing examples I tried in Basecamp - the result was better. In 4 it was the same, and in 2 it was slightly worse. 
So overall it is a modest improvement - but I would have hoped for a bit more. Still - clearly and improvement.

Hi all, 

attached is v2 of the patch, the binary is here:

Correction: the previous versions did not change angles like  this: /\
Improvement: For bicycle maps, the angle is changed up to 90° for arcs 
with high road speeds.

Options (--x-fix-sharp-angles  and --x-cycle-map) are the same.

@Felix: I wait for your feedback now, as I have no way to test with your style.

Gerd
