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.

  • Deprecated: kept for existing integrations, answered live from the same mapped zones and the same coverage rule as hazard_zones, which carries the reason for every unknown (flood_status, quick_clay_status, landslide_status) and should be used instead. True is a match in a mapped zone. False is no match in a kommune whose zones we hold (see /coverage). Null is unknown — the kommune is not covered — and never clearance; missing matches never establish absence of hazard.
  • Flood figures count present-climate zones only: flood_return_period is the lowest and flood_max_return_period the highest return period whose zone covers the point. in_flood_<n>yr is null inside a zone of another period, because NVE does not map every period everywhere. quick_clay_hazard_level is the most severe NVE grade at the point.

Fields

14 of 15 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.
