Cadastral surveying is the process of establishing or re-establishing the boundaries and subdivisions of land. It involves detailed measurement, mapping, and documentation of property lines and land ownership to create legal land records. Cadastral surveys provide critical information used in the preparation of legal documents such as deeds, leases, and titles, ensuring that property boundaries are accurately defined and recorded. This type of surveying is essential for land development, property transactions, land management, and resolving boundary disputes.
