[mkgmap-dev] Fwd: Wrong routing in some closed roundabount

Thu Jul 7 08:09:04 BST 2016

Hi Alexandandre,

I tried to reproduce the problem using the attached input file. Routing works for both cases.

So there is probably more to it. If you can reproduce the problem, please let me know how.

Gerd

Hi guys,

We note in our group a strange behavior in some roundabounts that are complete loops. Investigating, we discovered that when the starting and ending points of a roundabout coincides with a routable node, we are able to route through this roundabout. However, if the starting and ending points of a roundabout don't match a rountable node, we have problem to route through this roundabout.

The example bellow shows this clearly when trying to create a route em Mapsource from point A to B:

Thank you for your time.
