In December there was a thread (start:
<a href="http://lists.openstreetmap.org/pipermail/talk-be/2012-December/003367.html" target="_blank">http://lists.openstreetmap.org/pipermail/talk-be/2012-December/003367.html</a>)
containing some numbers/stats.
<br>
<br>
@Sander, *: is it possible to share your used method to pull these
stats (or just pull them again) and publish them on a 'frequent'
base (I'm not saying weekly, but what about +/- every 4 moths or
so)? In that way we can see a bit of our progress regarding this
'project'.

The method (overpass query) is mentioned in that link thread (Jo
points it out). On the subject..... I've been mapping a lot of
housenumbers lately, verifying my data against AGIV data before
committing to OSM... I can only conclude there is much work to be
done, AGIV is far from recent concerning new built houses, and OSM
itself has lots of issues regarding accuracy.<br>
<br>
I'm not too sure on the scientific significance of such a statistic
either. I would more than love to see stats that compair quality
of the entered addresses. (completeness , including postal code and
other addr:* tags, number of corrections etc. ) I've been
correcting a lot of mistakes and I start seeing a negative tendancy
in it:<br>
<br>
The ones that have done a LOT of input but didn't care to quality
check (validating even!) what they entered. I'll state this: I'm
cleaning up far too much crap others leave behind, I'm far from
perfect in my housenumbering too in this small village it's still a
huge undertaking, especially on complex corners where some numbers
of the same building belong to a different street. I have houses
I've changed 3 times in a row after visiting.<br>
<br>
Moreover, I see some people tagging the next city name on a street,
probably because they think it's in the next city, but OSM shouldn't
be a guessing game or a race to enter the most addresses if that
info is wrong.<br>
<br>
If someone has such an overpass query, I'm more than interested to
see those results, the rest looks like bragging rights.<br>
<br>
The AGIV site is valuable , even though it's slow. It's great tool
to verify what city a certain street belongs to. for example :
<a href="http://www.openstreetmap.org/?lat=50.998941&lon=4.426396&zoom=18&layers=M" target="_blank">http://www.openstreetmap.org/?lat=50.998941&lon=4.426396&zoom=18&layers=M</a><br>
<br>
De "Kleine Parijsstraat" belongs to Zemst, not Mechelen. If you
look this up in nominatim, it will tell you it's in Mechelen, which
is totally wrong. You will not find this street using AGIV in
Mechelen. But someone decided this was Hombeek(Mechelen) instead.
So the borders of Zemst where wrong as well as this was used to
determine these. The street above that "Boterstraat" can be found
in Mechelen, not in Zemst. Thanks to AGIV, I'm more certain when
those cases present. ( You can still see the old cached tile in some
zoom levels)<br>
<br>
But then again, I saw AGIV containing WRONG housenumbers too.
Verification in the field (twice) confirmed that what I had in mind
was matching reality. So it's like a triple check: a) know the
place b) visit it c) check with AGIV d) map a decent hous e) be
complete, using the plugins to add Country/postal code/streetname to
an address node so the data is easily searchable later.<br>
<br>
I really, really have to plea to everyone to enter _better_ data
than more ...., just instead of looking at the sheer number of
address info/nodes entered. It's quickly getting tired when I have
to keep cleaning up behind the top providers.<br>
<br>
I'll get off the soapbox now.<span class="HOEnZb"><font color="#888888"><br>
