Hello,

Thanks for spotting new buildings.

Two things please:

1) Despite it looks like you have been looking at UrbisAdm, your nodes are off by almost a meter each time and we had to check and redo everything.  It looks like you miscalibrated your background layer.

2) ref:UrbIS is a *unique* identifier for every building in the Brussels-Capital Region.  I suspect you have been copying the existing value from nearby buildings (I found ref 5048316 from housenumber 19 copied into housenumber 17, and ref 5048337 from housenumber 13 was apparently copied onto housenumber 15, which was also traced from you).
Please do not do that, adding fake data corrupts the database and generates validation issues.

We fixed it.
