Geocoding and reverse geocoding for Danish addresses.
Convert addresses to coordinates and coordinates back to addresses across all of Denmark — in WGS84 and ETRS89/UTM32N (EPSG:25832). 2.7M addresses, drop-in DAWA replacement.
Two directions, two coordinate systems.
Forward and reverse geocoding on the same address index — return coordinates in WGS84 for maps or ETRS89/UTM32N for GIS, with a single parameter.
Forward geocoding
Turn a street name, house number and postal code into precise lat/lon coordinates. Fuzzy matching handles imperfect input.
- Address → coords
- Fuzzy input
Reverse geocoding
Send a coordinate and get the nearest access address back — UUID, street, house number, postal code. Under 10ms.
- Coords → address
- < 10ms
WGS84 + UTM32N
Coordinates in WGS84 (lat/lon for web maps) and ETRS89/UTM32N (EPSG:25832, the Danish national grid for GIS).
- WGS84
- EPSG:25832
Coordinate lookup
Every address carries pre-computed coordinates, so geocoding is a single fast index lookup — not a slow on-the-fly calculation.
- Pre-computed
Spatial filters
Filter list endpoints by ?polygon=, ?cirkel=lon,lat,radius_m and ?srid=25832 — find every address inside an area.
- polygon
- cirkel
- srid
Batch geocoding
Geocode up to 1M rows in one batch job for migrations, data cleansing and bulk enrichment.
- Bulk 1M+
One API that grows with you. From first prototype to millions of lookups.
See all featuresCoordinates in. Address out.
Send a lon/lat pair and get the nearest Danish address back — with UUID, street, house number and postal code. Under 10ms.
// You only have a coordinatelon = 8.4501, lat = 55.4663
// Reverse geocode itGET /v1/adgangsadresser/reverse?x=8.4501&y=55.4663→ { vejnavn: "Schaubparken", husnr: "22", postnr: "6700", ... }

]Maps, routing and analytics.
Geocoding is the bridge between a text address and a point on the map — the foundation for navigation, catchment analysis and spatial joins.
Map pins from addresses
Forward-geocode customer addresses to drop accurate pins on a web map.
Routing & delivery
Coordinates feed route optimisation and delivery-window estimation.
GPS to address
Reverse-geocode a phone's GPS position into a deliverable address at check-in or report.
Spatial analytics
Join address data to regions, catchments and demographics for analysis and planning.
