The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDEr to verify and validate the geometry.
After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials. The minimum map resolution is 640 acres or one square mile. Generally, features under this size are not shown. There may be private inholdings within the boundaries of Federal lands in this map layer.
The geospatial part of this data set was originally extracted from the individual 1:2,000,000-scale State boundary Digital Line Graph (DLG) files produced by the U.S. Geological Survey which have a positional accuracy of 1,720 meters. It was updated several times using various sources whose horizontal positional accuracies are unknown.
Attribute and geospatial data
The National Atlas file was originally compiled from 1:2,000,000-scale Digital Line Graph files produced in the early 1980's. Between 1997 and 2003, the file was updated multiple times using a variety of Federal and State sources, both to adjust boundaries and to add or delete areas as appropriate. The final version of this file was produced in October 2003. Using Wildlife refuge area updates from the U.S. Fish and Wildlife Service, Wilderness area updates from the USDA Forest Service, Rocky Mountain Research Station, Aldo Leopold Wilderness Research Institute, and Wilderness area data from the National Wilderness Preservation System, the following updates were made: boundary updates to national wildlife refuges and wilderness areas; addition of several national wildlife refuges, waterfowl production areas, and wilderness areas; adjustment of wilderness study areas which had been converted to wilderness areas; and name corrections for several areas. Adjacent Federal lands having identical attributes were merged.
The following steps were performed by ESRI: Downloaded the compressed file from the National Atlas of the United Statesr and extracted it. Combined attributes FEATURE1, 2, 3, AGBUR, NAME1, 2, 3, STATE, and STATE_FIPS into a single attribute, summarized and dissolved on that attribute to reduce the number of features. Joined the tables to get back the original attributes. Reduced the attribute widths of FEATURE1, 2, 3, AGBUR, NAME2, and NAME3. Added SQMI attribute and calculated its values. Added NAMEFLAG attribute and calculated its values. Created ArcGISr layer file (.lyr), projection file (.prj), and spatial indices.

The primary or only type of Federal or Indian land and the owning agency. Where a polygon represents multiple Federal or Indian land types, this attribute describes the smaller or 'contained' land.

The secondary type of Federal or Indian land and the owning agency. Where a polygon represents multiple Federal or Indian land types, this attribute, in general, describes a land that surrounds or 'contains' the land referenced in FEATURE1. FEATURE2 may also be coded as 'Open Water' if a part of the Federal or Indian property referenced in FEATURE1 includes water.

The tertiary type of Federal or Indian land and the owning agency. Where a polygon represents multiple Federal or Indian land types, this attribute, in general, describes a land that surrounds or 'contains' the land referenced in FEATURE2. FEATURE3 may also be coded as 'Open Water' if a part of the Federal or Indian property referenced in FEATURE2 includes water.
