[OSM-talk] OSM the mediocre alternative

Hi Robert,

thanks for your comments:

Sorry I was not clear enough. I meant that a segment can belong to more 
than one way(S), and then it might be difficult to determine to which 
way the numberings belong to.

* A house is sited far away of the street which gives it the address 
(found on coutrysides). We will draw a serviceway or track to this 
house, but we will not give the serviceway the name of the street which 
forms the address

* There are two parallel roads. Between them, there are several blocks 
with many appartements. Neither are they spread systematically, nor are 
they aligned perpendicular to the streets which give them their names.
The blocks are connected by cycle- and footways only. Thus it is not 
possible (or at least very difficult) to tag the segments of the two 
streets (which form the address) with proper numbers.

Both cases can somehow modeled by tagging the segs of the streets, but 
if we want to achieve proper routing (and that's IMO the main purpose 
of collection house numbers), we need a smarter solution.

HTH & best regards,
