[mkgmap-dev] Admin relations

Sat Jul 14 07:49:09 BST 2018

Hi all,

the problem with e.g. Way 41230883 in Hennings real input data is this:
The LocationHook is used for all ways in the input file and the ways are not yet trimmed to the bounding box.
Now, with Hennings input file, the n/2-th point lies outside of the bbox, this node is ignored and mkgmap tries the first node (0) as next alternative. This node lies on the boundary between CHN and MNG, the returned result is more or less unpredictable.

I am not yet sure how to handle this. Working on it.

Gerd

Hi Gerd,
thanks for the fix, for the issue on Chinese side of the border it works
fine.
