title: GeoDanmark draft: false type: register

GeoDanmark is Denmark’s authoritative topographic vector reference dataset. It is a core component of Grunddatamodellen.

This page inherits shared contracts from Grunddatamodellen and only documents GeoDanmark-specific interpretation:

GeoDanmark is Denmark’s richest topographic dataset (73 classes, 9 thematic chapters). The routing table below maps each spec chapter to the correct leaf.

Minimum Interpretation Rules

  • GeoDanmark is a direct-geometry reference layer, not a normalized join graph like CVR.
  • The 73 feature classes span 9 thematic chapters (Bygninger, Bebyggelse, Trafik, Teknik, Natur, Hydro, Topografi, Diverse, DHMTilpasning) and route to 15 distinct leaves.
  • Many feature classes are topographic manifestations of broader concepts — always enter through the correct leaf first.
  • Spec reference: GeoDanmark Spec 6.0.2

Access Strategy

  • Use GeoDanmark when geometry quality is primary.
  • Join to DAR, BBR, or other registers when legal or administrative semantics matter more than topographic geometry.
  • Prefer direct feature extraction for bounded areas and campaign-aware comparison for change analysis.
