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.

Detailed zones exist only where NVE has commissioned mapping, mostly prioritised built-up areas. contains_address true is a TEK17 §7-3 safety-class matter; false outside mapped areas means unmapped, not safe. Complements the aktsomhet-based hazard_zones section.
Straight-line EPSG:25833 distances from the address point to the feature; not travel distance. Source features are imported as published, with their own accuracy and update cadence; updated_at is our import time.

Fields

2 of 11 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.
