[mkgmap-dev] [PATCH v1] Fix handling of housenumbers for street names changed by style

Sun Jun 1 12:18:25 BST 2014

Hi WanMil,

if I got that right, the user has to make sure that
a name change is applied to nodes and ways. Correct?

The patch changes the house number processing in such a way that it uses 
OSM elements how they are returned from the style processing.
The important thing is that street names of house number nodes are 
evaluated after style processing and not before.
