Cadastral Map
Definition
A cadastral map is a highly detailed spatial representation of land parcels, illustrating legal property boundaries, ownership details, and parcel identifiers. These maps serve as the backbone of land administration systems and are fundamental for legal, economic, and planning activities. They provide the legal and spatial foundation for defining property rights and responsibilities. Unlike general topographic maps, cadastral maps are tailored specifically for documenting ownership, land tenure, and taxation purposes. Modern cadastral maps are maintained using GIS platforms, allowing for real-time updates, integration with attribute data, and seamless sharing across public and private sectors.
Application
Cadastral maps are used by land registry offices, local governments, surveyors, real estate professionals, and developers. In urban planning, they help assess property suitability for infrastructure projects, zoning compliance, and land consolidation efforts. In rural contexts, they support agricultural land division, land reform programs, and forestry management. Cadastral data also plays a crucial role in disaster recovery, especially in determining rightful landowners after natural hazards. With digitized cadastres, governments can manage land transactions, minimize fraud, and increase public confidence in land tenure systems.
