Description:
Abstract: This is an aggregate national dataset describing the geographic boundaries of the ACEC within the BLM managed public lands. The designated ACECs are "areas within the public lands where special management attention is required to protect and prevent irreparable damage to important historic, cultural, or scenic values, fish and wildlife resources or other natural systems of processes, or to protect life and safety from natural hazards."
Purpose: These data are used when making management decisions and are intended to assist in the protection of the resources the ACEC was designated to protect. It documents where ACECs are located.
Supplemental Information: Each state office has a Data Steward or Contact Person for this data. Please contact the specific state office for additional information on their state dataset.

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 specific state office Point of Contact for additional information on provenance, history, accuracy and quality of their state's 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 76.95%.
Logical Consistency Report: This national dataset is an aggregation from multiple datasets provided by the BLM Administrative States, please contact the specific state office Point of Contact for additional information on provenance, history, accuracy and quality of their state's 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 9.3.1. 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 specific state office Point of Contact for additional information on provenance, history, accuracy and quality of their state's data. The completeness of this dataset reflects that of the source datasets.

Process Step:
Process Description: This ACEC data set has been modified to remove from sensitive data before public distribution. In the acec_desig_poly feature class, 112 polygons having either the "Restricted" or "Unknown" within the Sensitivity attribute field were removed. All Personal Identifiable Information was also removed from these feature classes as well.

Attribute:
Attribute Label: GIS_ACRES
Attribute Definition: This is a calculated value of area in units of acres based on the area field created by default within the ESRI Polygon data structure. For the purposes of a 'national data layer', the data are to be stored in geographic coordinates which do not correspond to ground values. This requires that there be a standard method for calculating this attribute. The method used for these data are as follows: The data are projected into a standard projection such as the ESRI default Albers projection for the continental United States, "US Albers NAD 1983." Once the data are projected, then a calculation of "SHAPE_Area (square meters) * 0.0002471044 = acres" is applied to the existing 'area' field that is default area created by the ESRI software resulting in the field (Attribute) 'SHAPE_Area'. Please note that the figure used in this calculation is the factor for converting the US Survey Foot value of for the length of a meter as opposed to the International Standard for converting meters and feet.
