Search Norwegian addresses by free text. Returns matching addresses with coordinates (EPSG:4258 / WGS84), postcode, postal area, municipality, and cadastre number (gårdsnummer/bruksnummer). Use when the user gives a street name or a full or partial address and needs the canonical record.

Reverse geocode: find the addresses closest to a latitude/longitude in Norway. Use when the user has coordinates and wants to know what is there.

Search Norway's official place-name registry (Sentralt stedsnavnregister / SSR). Covers farms, islands, mountains, fjords, lakes, urban areas, and other named natural features — not street addresses. Use for named places that aren't street addresses.

Get ground elevation in metres at a coordinate in Norway, from the national 1m digital terrain model. Returns elevation above sea level and the terrain type (open ground, forest, water, etc.).
