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

   Date: 1998 (process 1 of 6)

   The 2MILBD file was originally digitized by the National Mapping Division based on the sectional maps contained in 'The National Atlas of the United States of America' published by the USGS in 1970. The sectional maps were updated during 1978-1981 and digitized in the early 1980's. The data were updated in 1995 using 1:1,000,000-scale and 1:2,000,000 scale Bureau of Land Management State base maps. These data were published on CD-ROM in 1995. Using Arc/INFO software, the DLG optional format files were converted to Arc/INFO coverages using the DLGARC command. Only linear Federal land features and attribute information were extracted for inclusion. The individual State coverages were then merged together using the Arc/INFO command APPEND.

   Data sources used in this process:

   • 2MILBD

   Data sources produced in this process:

   • ATLAS-FEDL98

   Date: 1999 (process 2 of 6)

   The spatial and attribute information were updated using the Wild and Scenic Rivers web site. The data were aligned with ATLAS-HY and ATLAS-RD.

   • ATLAS-FEDL01

   Date: Sep-2005 (process 5 of 6)

   Parkways and scenic rivers were aligned with ATLAS-HY03 within the National Park areas in ATLAS-FEDP05, and were also aligned with National Park boundaries in ATLAS-FEDP05 as part of a National Parks update to ATLAS-FEDP05. The file was processed as a geodatabase before it was converted to a shapefile.

   Data sources used in this process:

   • ATLAS-FEDL01

   Parkways and scenic rivers were aligned with ATLAS-HY03 within the National Wildlife Refuge areas in ATLAS-FEDP06, and were also aligned with National Wildlife Refuge boundaries in ATLAS-FEDP06 as part of a National Wildlife Refuge update to ATLAS-FEDP06. The file was processed as a geodatabase before it was converted to a shapefile.

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 linear Federal Lands for all fifty States, Puerto Rico, and the U.S. Virgin Islands. Data completeness generally reflects the content of the original DLG files.
