Cadastral data includes the Public Land Survey System (PLSS) and Ownership
PLSS, the system of townships, ranges, and sections, was originally
established by the Land Ordinance Act of 1785. The U.S. Geological Survey
maintains this data, including a digital version at a scale of 1:100,000.
Ownership data is a product of the Montana Cadastral Mapping Project, a
public-private sector partnership to create, maintain, and disseminate a digital
GIS land ownership map database of the entire state.
