Dataset fields

name

Conservation area name

Source conservation name. Unnamed records use their reference where available.

designation

Conservation type

Area or church conservation. Restrictions follow the individual decision.

sourceAreaM2

Source area

Whole source record area in m², displayed as hectares. Not a sum of tile fragments.

reference

Conservation reference

Source conservation reference, which can be shared by several parts.

decisionYear

Conservation year

Year recorded by the source. Missing years are omitted.

decisionDate

Effective from

Source effective date where recorded; placeholder dates are omitted.

officialUrl

Conservation decision

Link to the authority's decision where the source supplies a valid URL. The conservation reference remains available when the link is missing.

sourceUpdatedAt

Source record date

Source record version date, not necessarily the conservation decision date.

Limitations and responsibility

Includes only Statuskode 3, Off_kode 1 and records with no ended system or validity period. A record is not necessarily a separate conservation case; parts can share a reference. Overlapping areas are not summed. Missing years (-1/0) and the placeholder date 1800-01-01 are not displayed as decision dates. The source does not supply municipalities. Older official decision links may have moved. The service reports no overall update date; retrieval identifies the edition.
