Description:
Abstract: This feature class represents the polygon features for active BLM Administrative Unit Boundaries at the Field levels. The Administrative Unit Polygon feature class was dissolved and saved as four separate feature classes, one for each administrative unit level, to display each as a separate layer.
Purpose: This feature class documents the physical boundary of administrative field units. In some cases, the administrative unit may manage areas outside of the boundary for other programs’ purposes.

Data Quality Information:
Attribute Value Accuracy Information:
Attribute Accuracy Report: This national dataset is an aggregation from multiple datasets provided by the BLM Administrative States. Please call the distributor for additional information on provenance, history, accuracy and quality of the data. The accuracy of attributes in this dataset reflects that of the source datasets. Attribute accuracy was tested by validating attribute coded values against accepted domain values, checking that alpha-numeric values followed a valid format, and checking that numeric values were greater than zero. The attribute total percent accuracy is 66.07%.
Logical Consistency Report: This national dataset is an aggregation from multiple datasets provided by the BLM Administrative States, please contact the distributor for additional information on provenance, history, accuracy and quality of the data. The logical consistency of this dataset reflects that of the source datasets. Each source dataset is run through a series of tests to verify that the data complies with the format specified in the Data Standard. ERRORS AND INCONSISTENCIES MAY STILL BE PRESENT IN THE DATA. These tests were conducted using ESRI ArcMap 10.1. The tests consisted of checking coded values for attributes against a domain of accepted values, checking that alpha-numeric values followed a valid format, and checking that numeric values were greater than zero. For the geometry, the topology was validated; however overlaps and gaps can still be found.
Completeness Report: This national dataset is an aggregation from multiple datasets provided by the BLM Administrative States, please contact the distributor for additional information on provenance, history, accuracy and quality of the data. The completeness of this dataset reflects that of the source datasets.
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: This national dataset is an aggregation from multiple datasets provided by the BLM Administrative States, please call the distributor for additional information on provenance, history, accuracy and quality of the data. The positional accuracy across this dataset varies according to the source.
Vertical Positional Accuracy:
Vertical Positional Accuracy Report: A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable.
Lineage:
Process Step:
Process Description: Using the implementation guidelines, GIS staff at BLM field and state offices cross-walk and clean up their data to comply with the standardized national dataset. Then, the BLM field and/or state offices submit the data to the National Operations Center (NOC), where it is compiled to produce seamless national datasets.
