What this does not say

Quoted verbatim from the section’s warnings field, exactly as the API returns it. They are not translated: a translation would show something other than what your response actually contains.

The source register is explicitly incomplete; absence of a nearby site is never evidence of clean ground, and a registered locality is not a measured condition at this address. Verify the case via faktaark_url.
Ten nearest registered sites by straight-line UTM33 distance. risk_class is the health-based condition class; 'Ikke satt' is common. NLOD 2.0, Miljødirektoratet.
Routes follow the car profile, from the address to the feature; ranking remains straight-line. Static modelled travel time excludes live traffic and emergency response. Road snapping is limited to 250 m at each end. Ferries may be included without timetable/wait guarantees. Graph source date is unverified unless supplied. © OpenStreetMap contributors, ODbL: https://www.openstreetmap.org/copyright
walk_route and cycle_route follow OSRM's foot and bicycle profiles on the same OpenStreetMap data: paths and stairs allowed on foot, road rules for bicycles; modelled times at profile default speeds, not measured.

Fields

5 of 14 fields are value fields — the ones that decide whether a record actually says anything. The rest are context: identifiers, codes and timestamps. Fields marked “open” return values to anonymous callers; the rest require a key.
