cadastrais

Cadastrais refers to the data, records, and processes associated with cadastral systems, the official registers and maps that describe land parcels, their boundaries, ownership, rights, and usage within a jurisdiction. Cadastral information combines parcel geometry (boundaries, polygons, area) with attribute data such as parcel identifiers, current owners or holders, legal descriptions, rights and restrictions, fiscal information, and improvements.

Cadastral data serves multiple purposes in land administration and governance. It underpins property taxation, land registration, urban and rural planning, and the resolution of boundary or ownership disputes. By detailing who owns what, where, and under which conditions, cadastral records provide a foundation for transparent property markets and efficient public services.

Creation and maintenance of cadastral data typically involve land surveys, deeds, and official registrations. Parcels may be created, subdivided, merged, or revalued, with changes recorded by a land registry or cadastre authority. Modern systems increasingly rely on geographic information systems (GIS) to manage, visualize, and update parcel data, and to link maps with legal documents and ownership records.

Technology and standards play a key role in interoperability. Many cadastres use GIS-based solutions and adopt international standards such as the ISO 19152 Land Administration Domain Model (LADM) to model land tenure, parcels, and rights in a consistent way. This facilitates data sharing across agencies and borders and supports modernization efforts like digital cadastres and integrated land administration.

Cadastrais data is legally significant in many jurisdictions, serving as official evidence of property boundaries and rights. Its accuracy, currency, and accessibility are central to reliable land governance and planning.
