Why was the data set created?

These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the National Atlas of the United States in the use of these data.

2. How were the data generated, processed, and modified?

   Date: Dec-2004 (process 1 of 3)

   Working in Arc/INFO, Indian reservations and Federal lands internal to them were extracted from the National Atlas Federal Lands map layer. Isolated features under 640 acres were deleted. Attributes for feature type, name, administering agency, State, and State FIPS codes were retained. Adjacent Indian reservations having the same feature type, name, and administering agency were merged. State attributes of merged Indian reservations were then updated. Names for non-Indian lands were deleted. For polygons without label points, the points were created and the polygons were assigned a null value.

   Data sources used in this process:

   • ATLAS-FEDLN_0310

   Data sources produced in this process:

   • ATLAS_INDLN_200412

   Date: Sep-2005 (process 2 of 3)

   The boundaries from ATLAS_INDLN_200412 were aligned to National Park boundaries from ATLAS-FEDLN_200512 as part of a National Parks update to ATLAS-FEDLN_200512. The file was processed as a geodatabase before it was converted to a shapefile.

   Data sources used in this process:

   • ATLAS_INDLN_200412
   • ATLAS-FEDLN_200512

   Data sources produced in this process:

   • ATLAS_INDLN_200512

   Date: Jun-2006 (process 3 of 3)

   The boundaries from ATLAS_INDLN_200512 were aligned to National Wildlife Refuge boundaries from ATLAS-FEDLN_200606 as part of a National Wildlife Refuge update. The file was processed as a geodatabase before it was converted to a shapefile.

   Data sources used in this process:

   • ATLAS_INDLN_200512
   • ATLAS-FEDLN_200606

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

2. How accurate are the geographic locations?

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   This map layer includes Indian reservation polygon features for the United States. The minimum map resolution is 640 acres or one square mile. Generally, features under this size are not shown.

5. How consistent are the relationships among the observations, including topology?

   Using ESRI's ArcInfo GIS software, the map layer was checked for label errors, dangling nodes, and intersections. Polygon topology was built for the map layer.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
