The use of relations is often required when the house/building is far away from the street. Here's an example of a building which is 700m away from the associated street: <a href="http://www.openstreetmap.org/way/75194717#map=16/41.3786/-73.5284">http://www.openstreetmap.org/way/75194717#map=16/41.3786/-73.5284</a><br><div><br></div><div>It probably needs a relation setup as most routers will not search far enough for the street (or it may be on another tile).</div><br><div class="gmail_quote">On Mon Dec 01 2014 at 6:24:20 AM Andrzej Popowski <<a href="mailto:popej@poczta.onet.pl">popej@poczta.onet.pl</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Gerd,<br>

Doesn't mkgmap verify street names of an address and a way? The problem<br>
is that relation can be created *instead of* putting addr:street to node<br>
or building.<br>
<br>
See real examples and look at "house" members:<br>
<a href="http://www.openstreetmap.org/relation/65769" target="_blank">http://www.openstreetmap.org/<u></u>relation/65769</a><br>
<a href="http://www.openstreetmap.org/relation/31709" target="_blank">http://www.openstreetmap.org/<u></u>relation/31709</a><br>
<br>
I have compiled area around relation 65769 and there is no<br>
Berngariusstrasse 2, 5, 6, 8 in address search. The only house number is<br>
1, in which case building include addr:street tag.<br>
<br>
