plat and cadastral
According to Wikipedia:
“In the United States, a plat […] is a map, drawn to scale, showing the divisions of a piece of land. […] City, town or village plats show subdivisions into blocks with streets and alleys.”
That Wikipedia page also introduced me to the term cadastral, which my dictionary defines as “showing or recording property boundaries, subdivision lines, buildings, and related details.” Cadastral derives eventually from Late Greek katastichon, meaning “notebook.”
