Cognised existence: A historical map sheet is a defined geographic area for which a printed or drawn cartographic product was produced. The sheet division records which map series, scale, and time period a given area was covered by — serving as an index into Denmark’s cartographic heritage.

Question: Which historical map sheet covers this location, and what cartographic source does it represent?


Realisations

1. HistoriskeKortbladsinddelinger — Map Sheet Index

HistoriskeKortbladsinddelinger provides polygon footprints of historical map-sheet divisions.

Spatial Access Path

HISTKORT_Kortbladsinddeling → GM_Surface polygon (direct geometry, no joins)

Each sheet division carries its own polygon geometry representing the geographic extent of a single map sheet.

When to Use This Leaf

  • Archival georeferencing: finding which historical map covers an area of interest and linking to the scanned source via HKPNlink.
  • Cartographic history: understanding how Denmark’s mapping evolved across map series and scales.
  • Heritage analysis: relating modern features to their historical cartographic representation.
  • Temporal context: the maalt_aar and udgivet_aar attributes document when an area was surveyed and published, useful for understanding the provenance of historical spatial information.

For modern topographic or cadastral data, use Transport Networks, Cadastral Parcels, or Elevation instead.


Temporal Model

Bitemporal. Sheet divisions are versioned through virkningFra/virkningTil, but in practice most records represent a stable historical footprint. The maalt_aar and udgivet_aar attributes capture the cartographic temporal provenance directly.
