Cadastre

A cadastral map (shortened to cadastre or cadaster) is a comprehensive land recording of the real estate or real property's metes-and-bounds of a country.[1][2]

In most countries, legal systems have developed around the original administrative systems and use the cadastre to define the dimensions and location of land parcels described in legal documentation. A land parcel or cadastral parcel is defined as "a continuous area, or more appropriately volume, that is identified by a unique set of homogeneous property rights".[3]

In the United States, Cadastral Survey within the Bureau of Land Management (BLM) maintains records of all public lands. Such surveys often require detailed investigation of the history of land use, legal accounts, and other documents.

The cadastre is a fundamental source of data in disputes and lawsuits between landowners. Land registration and cadastre are both types of land recording and complement each other.[2]
