Hi everyone :)

i take some times to look more in the data of urbis,
i also played with qgis to try to extract some informations...
i started with buildings and addresses as i think it's the weakest point in
brussels...

So here is my take on etterbeek (as it's a small one):

I split it in 3 files :
- buildings without addresses
- building with 1 address (address on the building shape)
- building with more than 1 address (address as diffrent points)

What do you guys think?


before uploading there is still some work to do :
- check for duplicated node or self intersecting buildings
- check for existing buildings / address in osm

Any comments?
