[mkgmap-dev] Problem using housenumber option

Fri Feb 22 08:11:50 GMT 2013

Hi,
I'm trying to generate a map of Italy using house numbers option (--x-
housenumbers) with latest mkgmap (r2494). I see this output traces:

Exiting - if you want to carry on regardless, use the --keep-going option

and the gmapsupp.img is not created at all.

Trying to debug a little bit, i found that the problem seems to be related to 
this OSM element:

 <relation id="2198742" user="Pab09" uid="178610" visible="true" version="2" 
changeset="13345939" timestamp="2012-10-03T11:17:51Z">
  <member type="way" ref="31563508" role="outer"/>
  <member type="way" ref="165015469" role="outer"/>
  <tag k="addr:housename" v="Hidron"/>
  <tag k="addr:housenumber" v="055892500"/>
  <tag k="addr:postcode" v="50013"/>
  <tag k="addr:street" v="Via di Gramignano"/>
  <tag k="leisure" v="sports_centre"/>
  <tag k="name" v="Hydron"/>
  <tag k="sport" v="swimming"/>
  <tag k="type" v="multipolygon"/>
 </relation>

As you can see, addr:housenumber is not a valid house number (in fact it seems 
to me a telephon number !). 
However, there is, possibly, a missing check on what is supposed to be a valid 
housenumber (probably a sort of sanity check is needed: not all numbers could 
be used as house numbers, at least in relation to garmin img format 
limitations).

I'm not sure, but I think the same problem is present with other OSM element, 
at least, in Italy.

Thank you to all of you for your attention and for your excellent work !
