Cadastrale

Cadastrale is an adjective used in several Romance languages to refer to matters related to cadastre, the public record of real estate. A cadastre, or cadastral system, is a comprehensive register that maps and documents land parcels, their boundaries, area, and sometimes value and ownership. In many jurisdictions, the cadastre focuses on the spatial geometry and legal descriptions of parcels, while a separate land registry records title and property rights. The two systems may be linked in a unified cadastre-land registry.

Purpose: to support property taxation, land use planning, development control, and legal certainty for buyers, sellers, and lenders. It provides a basis for determining taxes, assessing real property, and resolving boundary disputes.

Components: parcel geometry (boundaries, coordinates, area), parcel identifier, cadastral maps or plans, ownership information, rights and restrictions (easements, mortgages), land use, improvements. Data are maintained in a cadastral database and usually distributed via GIS.

Process and governance: cadastral data are created and updated through surveys, subdivision, merging or splits of parcels, and boundary adjustments, often following legal procedures. A cadastral authority or land registry maintains the records and may provide access to the public, subject to privacy rules. The system may be bilingual with heavy reliance on digital mapping.

Variations: some countries separate cadastral and title registries; others integrate them. Historically cadastres supported taxation and feudal administration; today they support planning, taxation, and property rights with digital cadastres becoming common.
