[mkgmap-dev] order of lines / roads

Wed May 8 10:07:54 BST 2013

Be careful with changing this all, the draw order of lines are very unpredicatable,
and it also varies between different GPS units.

> a few more remarks:
> 1) the relation processing also adds ways (those with the fake ids
> like 4611686018427387918). These are added after the normal OSM ways
> and the order is
> determined by algorithmns.
> 2) another possible solution might be to sort the lines by type before
> they are written to the img file. This would require an additional
> file giving the draw order of line types.
