[OSM-talk-be] Properties sitting in the corner of streets

[Gert Van Oost]

Or maybe also with this simpler way……

Just keep the parcels that share a boundary with a ‘Kruispuntzone’ in the GRB-layer ‘wegbaan’ (‘GRB-WBN’ -polygons) https://overheid.vlaanderen.be/help/grb/objectcatalogus/wegbaan-wbn
or clossest to the point-layer  ‘GRB-wegknoop’  (https://overheid.vlaanderen.be/help/grb/objectcatalogus/wegknoop-wkn)
GRB-WKN

greetings

Hi Mehmet,

This isn't something we would map in OpenStreetMap itself. I'm sure on GIS fora you will find hints on how to do this analysis.

Two more strategies off the top of my head:
- download the parcel data (see https://www.geo.be/catalog/details/tt098dcb-f5c7-49b8-8e0b-7c3811630d85?l=en) and use that in combination with your other data. You could keep just the sides that do NOT share a border with other parcels. Then for every subsegment of the border, find the nearest street. If the parcel has more than one different nearest streetname, it might be on the corner. You might even look at angles of subsegments to rule out false positives and false negatives
- simply look at the addresses on this building. Sometimes corner houses have an address from both streets. Or look at the addresses of the nearest buildings (use streets as barriers)

Hello everyone,

I am trying to predict house prices in Flanders and Brussels. As I know, whether a property sits in a corner of a street plays an important role in the predictions. So far I tried to spot them via street intersections using some OSM shape files. However, it turned out that it is a quute challenging task and I have failed. So I was wondering if OSM has already such info for Belgium ?

Thanks in advance!

Mehmet
