Hva dette ikke sier
Gjengitt ordrett fra seksjonens warnings-felt, slik API-et returnerer det. Vi oversetter dem ikke: en oversettelse ville vist noe annet enn det svaret ditt faktisk inneholder.
- Estimate, not a measured or registered building height and not the storey count in Matrikkelen: the laser-scanned surface minus the terrain inside the footprint, from Kartverket's national elevation model, whose scan year varies by area. A building built, extended or demolished after the scan is not as it stands.
- Method dom-dtm-height-v1. The footprint is rasterised on the 1 m grid and eroded by one cell so walls and eaves mixing with ground do not count; at least 4 cells are needed. height_p95_m is near the ridge (a chimney or antenna does not move it), height_median_m the typical roof height. estimated_storeys = round(height_median_m / 3 m), at least 1: 3 m per storey is a common floor-to-floor allowance, and a pitched roof's median lies between eaves and ridge, so loft storeys count only under a high roof. Null when the median is under 2 m (no building in the surface model).
- matrikkel_storeys is the storey count registered in Matrikkelen, shown for comparison; null when not registered. footprint_source 'osm' is an OpenStreetMap outline matched to the Matrikkel building number (ODbL, © OpenStreetMap contributors); 'roof_blob' is the roof shape detected under the Matrikkel building point when no outline is held; 'address_point' means neither was found and every figure is null. FKB building outlines are not used.

- validation lists each figure the model is checked by, against the reference named in it. value null with status not_yet_computed means the check has not been run on the data yet; it is not a pass.
