Land Status

The layers on this page are produced by combining the Bureau of Land Management's Alaska Case Retrieval Enterprise System (ACRES) with the official protracted section grid. The same data is available in the SDMS Map Interface, under the "Land Status - Detailed" layers folder.

See the metadata for a description of each dataset and attributes associated with it.

These layers are available as shapefiles only in the NAD 83 datum.
