Matrikkagrupper

Matrikkagrupper is a term used in the context of the Norwegian cadastral system to describe a logical grouping of parcels within the matrikkel, the national land registry. The concept is not a formal land division in itself, but a way to organize property data for administration, data exchange, and geographic information systems. The exact definition and usage can vary between datasets and agencies, and the term is not universally standardized across all cadastral systems.

Purpose and use

Matrikkagrupper are typically employed to facilitate management tasks such as property data updates, taxation, zoning, and planning processes. By grouping several matrikkelparcels that share a geographic area or administrative responsibility, authorities can streamline workflows, improve data consistency, and support efficient querying and reporting. The groups are usually used internally within GIS and registry applications rather than as distinct public-facing land divisions.

Composition and relation to standard identifiers

A matrikkelgruppe contains multiple matrikkelobjekter (parcels) that possess individual identifiers within the matrikkel system. A property in the matrikkel is commonly described by components such as a municipality code, gårdsnummer (gnr), bruksnummer (bnr), and sometimes sub- or unit numbers. While a matrikkagruppe aggregates several parcels, it does not replace the fundamental cadastral identifiers but rather serves as a structural or administrative layer on top of them.

Variations and availability

Because implementations differ, the presence and exact structure of matrikkagrupper can vary by municipality, registry system, or data provider. For users, it is mainly relevant to GIS professionals, data integrators, and administrative staff working with cadastral and planning data.
