[mkgmap-dev] [PATCH] reverse dead-end ways (to avoid routing problem?)

Sat Feb 14 16:46:19 GMT 2009

Interesting...

Looking at:

http://www.cgpsmapper.com/tool.htm#1

It says of the MapRoute program:

# Fix several potential problems in routable maps

    * setting NodID point always at the beginning and end of the road (important for dead-end roads) 

Perhaps, adding a node at the dead-ends is a must.

Something else has just occurred to me. Hasn't it been reported previously
that people were seeing the pink line go to the wrong end of motorways?

I wonder if that's related to our current issue and was caused by the
fact that the motorway was incomplete (or was clipped!) and so one or
more of its ends were not terminated with nodes. You can't reverse the
direction of the motorway, so making its ends into nodes would be the
only option.

So, the best approach may be making all dead-ends into nodes, after all.

I shall make a patch to do that.
