    • BLM MT SMA Surface Ownership Polygon

    Metadata Updated: January 25, 2026

    Surface Management Agency: The Surface Management Agency (SMA) Geographic Information System (GIS) dataset depicts Federal land for the State of Montana, and classifies this land by its active Federal surface managing agency. A Federal SMA agency refers to a Federal agency with administrative jurisdiction over the surface of Federal lands. Jurisdiction over the land is defined when the land is either: Withdrawn by some administrative or legislative action, or Acquired or Exchanged by a Federal Agency. This layer is a dynamic assembly of spatial data layers maintained at various federal and local government offices. The GIS data contained in this dataset represents the polygon features that show the boundaries for Surface Management Agency and the surface extent of each Federal agency's surface administrative jurisdiction. SMA data depicts current withdrawn areas for a particular agency and (when appropriate) includes land that was acquired or exchanged and is located outside of a withdrawal area for that agency. The SMA data does not illustrate non-federal land status ownership pattern boundaries or contain land ownership attribute details. Current information for other Federal and State agencies can be found on their respective entities.
