Updated "no address" Layer on

Posted by SimonPoole on 25 March 2013 in English (English)

The "no address" layer on now highlights landuse=residential layers that don't contain addresses. I originally intended to do this based on address density, but that doesn't seem to make a lot of sense at the current point in time.

Here an extreme example of how the new layer looks near Atlanta:

You can see bits of green on the above map from the new "has address" layer that highlight buildings and nodes with addresses. With the B&W backgroud you can get a good overview of where we actually have addresses:

More information can be found on the wiki.

Nice work Simon, this will be very useful

I've been wondering if there's a way to show the % of building's with Vs without address information. I'm thinking some kind of graph would be best, something along the lines of a pie chart or simple line graph if historical information is available i.e. the growth of building ways and another line on the qty of buildings with address info. Not sure on the specifics, but I think something like that would be very useful

Dear Simon,

Your map is very nice. However, it is also common practice to place the addr:housenumber point where it is actually located, e.g. on the fence which marks the limit of property, and not on the building itself.

Could it be possible to test that one addr:housenumber POI is at less than n meters away from one building. Sure this will not get rid of all "false positive", but it should reduce their number.

See this location for example where almost all addr POIs are less than 5 meters away from buildings

IMHO it is actually not such a common practice (legally naturally countries differ greatly in what actually has a number, the lot, the building or an entrance) and doesn't seem to be documented (not that that means very much).

In any case it would be rather expensive to change the queries so that such a node would get included simply by expanding the building polygon or similar (not to mention that it would generate tons of false negatives). It might be possible to support it if the node is actually on a fence polygon enclosing the house, which however doesn't seem to be the case in your example.

Hello Simon, if you look at the OSM wiki about

that page is not so well linked yet.

So until now I did not know that it exist ;.)
