This spatial data contains Surface Management Agency (SMA, also sometimes called Land Status) information for Idaho. It shows categories for Federal and State agencies as well as Private lands in Idaho. For government land, this data displays the MANAGING AGENCY of the land, which may or may not be the same as the "owning agency" of the land. SMA is sometimes referred to as "ownership", although this term is inaccurate when describing public lands. The Bureau of Land Management (BLM) in Idaho creates and maintains this spatial data. This dataset is derived by dissolving based on the "owner_type" field from the master SMA GIS dataset (which is edited often) kept by the BLM Idaho State Office. Originally, the primary source of the GEOMETRY of the features was the BLM Geographic Coordinate Database (GCDB). In areas where GCDB records are unavailable, the spatial features are taken from a variety of sources including the BLM Idaho Resource Base Data collection, US Geological Survey Digital Line Graphs (DLGs), and US Forest Service Cartographic Feature Files (CFFs), among others (see Process Steps). It should be stressed that the geometry of the data may NOT be GCDB-based, and the GCDB-based features are not necessarily being edited to match improved GCDB, therefore this data should NOT be considered actual "GCDB data". For the latest GCDB spatial data, please download it from http://www.geocommunicator.gov The source of the ATTRIBUTE information is an ongoing effort to coordinate between the BLM Master Title Plats (MTPs), the BLM case files and Realty Staff, the BLM LR2000 database, cooperation with other government agencies that own or manage land parcels, and users of the data. The data for other agencies may not be accurately represented if the information was not provided to the BLM by the managing agency. BLM gives its best effort to attribute the parcels properly, but when errors are found, please contact the BLM Idaho State Office Geographic Sciences department at 208-373-3950. Please get a fresh copy of this data a couple times a year as the SMA data is constantly changing. Official actions that affect the managing agency are finalized each day, and changes to correct found errors are always being updated. Nevada SMA data was acquired from the BLM Nevada web site and clipped to the area that is managed by Idaho BLM Boise District.
