Bytero Property Records
One row per registered building number: its address, its type, its size measured on the national laser scan, its flats, and its year built and wall material where we know them.
What a row is
One row is one building as the cadastre numbers it: PROPERTY_ID, the address and the point, the type of the building and the parcels it stands on. The other fields are filled where we hold the fact; an empty value means we do not hold it, not that the building lacks it.
How the values are made
Size. The footprint, the heights of the ridge and the eaves, the volume and the roof form are measured on the national laser scan; the number of storeys is estimated from the height. A roof is given to a building only when it is the nearest roof within 15 m and no other building number claims it, so garages in rows and terraced houses often carry no size.
Flats. The cadastre does not record the floor area of a flat. It follows from the registered ownership shares, and covers the rooms and the accessory rooms of the flat, without balconies. FLAT_AREA_BASIS says whether the shares of the building state areas.
Year built. An estimate with its earliest and latest year, read from maps, aerial photographs and records (Bytero Origin 2.0), or the year of the first sales of a new building. NUMBER_REGISTERED_YEAR marks buildings whose house number was created in the address register from 2017 on.
Wall material. For apartment blocks: modelled, or stated by the adverts of flats in the block where they agree.
What it is not
The table holds no owners and no ownership data. The year built is an estimate with a range, not a register entry.
