Summary

This data is provided for the public use. It is intended to represent Federally acquired lands in California and portions of northwestern Nevada.

Description

            

This layer is updated as Lands are acquired by BLM and entered into the Bureau Master Title Plats and Legacy Rehost System (LR2000), and includes the serial number associated with each acquisition. This layer is also updated whenever BLM is notified that Lands have been acquired by other Federal Agencies. For addtional information regarding an acquistion search the Bureau's LR2000 system:

http://www.blm.gov/lr2000/

and the Bureau's General Land Office Records:

http://www.glorecords.blm.gov/search/default.aspx#searchTabIndex=1

This data has been maintained since 2000. Acquistions prior to 2000 are gradually being added as part of the Bureau's ongoing Land Records Data Quality Clean up efforts.

The source geometry is from California BLM LND_SurfaceEstate data which 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.

Use limitations

            

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.

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. These 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 User 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.

These data are for general purposes related to Geographic Information System and mapping applications at small to intermediate geographic scales. Users are cautioned that digital enlargement of these data to scales larger than that at which they were originally mapped can cause misinterpretation. Users are further cautioned that these data and interpretations derived from them do not eliminate the need for onsite survey and evaluation of specific sites.

Supplemental information
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.

Lineage 

Lineage statement
View representing lands acquired by BLM in California and NW Nevada. This is a view of data located in from BLM CA LandSurfaceEstate dataset.
