The SMA feature class covers the continental United States, Alaska, Hawaii, Puerto Rico, Guam, American Samoa and the Virgin Islands. 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 Jurisdiction over the land is defined when the land is either: Withdrawn by some administrative or legislative action, or Acquired or Exchanged by a Federal Agency.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 SMA data depicts current withdrawn areas for a particular agency and (when appropriate) includes land that was acquired or exchanged and is located outside of a withdrawal area for that agency.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 do not illustrate land status ownership pattern boundaries or contain land ownership attribute details. The SMA Withdrawals feature class covers the continental United States, Alaska, Hawaii, Puerto Rico, Guam, American Samoa and the Virgin Islands. A Federal SMA Withdrawal is defined by formal actions that set aside, withhold, or reserve Federal land by statute or administrative order for public purposes. A withdrawal creates a title encumbrance on the land. Withdrawals must accomplish one or more of the following: A. Transfer total or partial jurisdiction of Federal land between Federal agencies. B. Close (segregate) Federal land to operation of all or some of the public land laws and/or mineral laws. C. Dedicate Federal land to a specific public purpose. There are four major categories of formal withdrawals: (1) Administrative, (2) Presidential Proclamations, (3) Congressional, and (4) Federal Power Act (FPA) or Federal Energy Regulatory Commission (FERC) Withdrawals. These SMA Withdrawals will include the present total extent of withdrawn areas rather than all of the individual withdrawal actions that created them over time.

The SMA data do not illustrate land status ownership pattern boundaries or contain land ownership attribute details. The purpose of this dataset is to fulfill the public and Government’s need to know what agency is managing Federal land in a given area, and for use by BLM Staff for use in analysis and reports. This dataset is useful as a tool to determine and illustrate the boundaries of a particular Federal agency’s “managing” area and to quantify these areas in terms of geographic acreage.

Scholarly information considered in Departmental decision making must be robust, of the highest quality, and the result of as rigorous scientific and scholarly processes as can be achieved. Most importantly, it must be trustworthy. This policy helps us to achieve that standard (https://www.doi.gov/scientificintegrity) The goal of this work is to provide a current and consistent view of the Federal Surface Management Agency for federal lands in the United States. Non-Federal lands are represented in general terms, Undetermined (UND), Private (PVT), State (ST), and Local Government (LG). More detailed information on non-federal lands will need to be acquired from other sources. Foundational to the SMA data is the expectation that it topologically align where possible and appropriate with the official published version of Bureau of Land Management (BLM) Public Land Survey System (PLSS), and the Cadastral National Spatial Data Infrastructure (CAD NSDI) GIS Data. Relationships exist between SMA and the following core data sets: Special Public Purpose Withdrawals (SPP_WithdrawalAreas), Surface Management Agency Withdrawls (SMA_Withdrawls), BLM Master Title Plats (MTP), BLM Legacy Rehost 2000 (LR2000), BLM Control Documents (CDI), BLM Historical Indicies (HI), BLM Geographic Coordinate Database (GCDB), Non-BLM Public Land Survey Statistics (PLSS from other sources), Non-BLM plat or land status data, and Public Land Statistics.

BLM-Nevada was unable to review their state-based SMA data set and certify that the data used in the creation of this data set was the most current and accurate. Foundational to the SMA data is the expectation that it topologically align where possible and appropriate with the official published version of Bureau of Land Management (BLM) Public Land Survey System (PLSS) Cadastral National Spatial Data Infrastructure (CAD NSDI) GIS Data. Topology rules: SurfaceManagementAgency polys must not overlap. Data set is considered complete for the information presented. No Subsurface with this rendition. The completeness of the data can be determined by looking at the number of polygons that have been surveyed. If a polygon is identified as being either unsurveyed protracted or unsurveyed unprotracted, it has not been surveyed and will not have survey measurements. In other cases, the BLM was not able to completely abstract all the information from survey plats and notes due to the complexity of the data. Users are advised to read the rest of the metadata record carefully for additional details. The spatial accuracy of the data can be found from the reliability and/or the error in X, Y coordinates contained in the PLSSPoints feature class. This represents the best estimate of spatial accuracy on a point-by-point basis. BLM-Nevada was unable to review their state-based SMA data set and certify that the data used in the creation of this data set was the most current and accurate. Collected the Surface Management Agency feature classes from each of the BLM State Offices, and related the attributes in the State Office feature classes to a standard attribute schema stored in master federal units attribute table. 2023-10-06T00:00:00 Michael Sarhan Bureau of Land Management, National Operations Center Geospatial Data Analyst (303)236-6806
