Surface Management Agency Alaska Native Lands

Surface Management Agency Alaska Native Lands This feature layer, utilizing National Geospatial Data Asset (NGDA) data from the Bureau of Land Management (BLM), displays the Surface Management Agency's (SMA) areas classified as Alaska Native Lands within the larger federal land management framework. According to BLM, “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 Jurisdiction over the land is defined when the land is either: Withdrawn by some administrative or legislative action, or Acquired or Exchanged by a Federal Agency.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.” English Bay Corporation Data currency: This cached Esri federal service is checked weekly for updates from its enterprise federal source (Alaska Native Lands (Patented or Interim Conveyed)) and will support mapping, analysis, data exports and OGC API – Feature access.
