Data is intended to represent federally administered lands in California and portions of northwestern Nevada. This representation uses clear text fields to explicate numeric coded values.
The LND_SurfaceEstate data illustrates the location of Federal and State managed lands in California and portions northwest Nevada. The data is developed and maintained at the BLM California State Office in Sacramento. Data development efforts focus on accurately depicting the locations of BLM managed lands. Private and non-governmental lands are categorized as unclassified. Other Federal agencies, the State of California , and numerous County governments contribute much of the information and data incorporated into this geodatabase. Data for lands in Nevada were obtained from the Bureau of Land Management, Reno, Nevada.

PUBLIC DATA. These data are provided by Bureau of Land Management (BLM) "as is" and might contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. Generally, these data are intended for small scale (1:24,000 and smaller) natural resource management and planning applications.
The information contained in these data is dynamic and may change over time. The data are not better than the sources from which they were derived, and both scale and accuracy may vary across the data set. These data might not have the accuracy, resolution, completeness, timeliness, or other characteristics appropriate for applications that potential users of the data may contemplate. The User is encouraged to carefully consider the content of the metadata file associated with these data. The data are neither legal documents nor land surveys, and must not be used as such. Official records may be referenced at most BLM offices. Please report any errors in the data to the BLM office from which it was obtained.
The BLM should be cited as the data source in any products derived from these data. Any Users wishing to modify the data should describe the types of modifications they have performed. The Users should not misrepresent the data, nor imply that changes made were approved or endorsed by BLM. This data may be updated by the BLM without notification.

The LND_SurfaceEstate data is edited and maintained in a single polygon feature class. Whenever possible, BLM lands are constructed from the Public Land Survey System (PLSS), also available to the public (PublicLandSurvey.gdb). Alignment of BLM data with the PLSS is a continual process, as the accuracy and density of PLSS data continues to improve and develop. Issues of misalignment with the PLSS are more common with non-BLM management areas. These discrepancies are being addressed at the BLM California State office based on U.S. Department of Interior priorities throughout the State of California.

Polygons are checked to be sure all polygons have at least one set of attributes, and no more than one set of attributes. Polygon edges are examined to be sure that they close correctly.
Updates emphasize BLM ownership. Other ownership categories will be updated as opportunities become available.
Accuracy is evaluated primarily through use of the data, and at the time the data is updated or otherwise edited.
