[mkgmap-dev] [Patch v2] addr:interpolation

Sat Dec 20 12:45:44 GMT 2014

Hi Gerd,

I didn't expect a big improvement by supporting addr:interpolation. 
There are only few things I can imagine:
* addr:interpolation is tagged with addr:street but the nodes with 
addr:housenumber are not tagged with addr:street
* addr:interpolation span over more than one street segment

I am curious about your results!
