Cadastral Map

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

Metes and bounds is a system or method of describing land, real property  or real estate. Newer systems include rectangular (PLSS, government survey) and lot and block (recorded plat). The system has been used in England for many centuries and is still used there in the definition of general boundaries.  By custom, it was applied in the original Thirteen Colonies that became the United States and in many other land jurisdictions based on English common law
The maps together with a record of tracking ownership of land would be a cadastre.
The system was used here in Tulare County as late as 1959. 
Although the system is gone, the name has stuck- cadastral mapping

Bonus question: what does beating of the bounds refer to?
