Conte National Wildlife Refuge, Vermont (Fish and Wildlife Service)Data sets were obtained from the State, regional, or field offices of the federal agencies which own or administer the newly created lands. The data were re-projected, generalized, and integrated into the existing federal lands data set. Hanford Reach National Monument, Washington (Fish and Wildlife Service) and the expansion of Pinnacles National Monument (National Park Service) are not included in this release. The California Coastal National Monument consists of thousands of Bureau of Land Management-administered islands, rocks, exposed reefs, and pinnacles above high mean tide, within twelve nautical miles of the shoreline, between Oregon and Mexico. The National Monument is shown in the Federal Lands data set as a polygon which encloses this area.
All National Park Service lands in the existing Federal Lands data set were reviewed using a national boundary coverage, NPS-BND99. Some adjustments were made to resolve discrepancies between National Park Service data and existing National Atlas boundary data.
An inventory of all wilderness areas was conducted in cooperation with the Aldo Leopold Wilderness Research Institute. Wildernesses that were missing and that were larger than the minimum map resolution of 640 acres were acquired from the State, regional, or field offices of the land-owning agencies. The data sets were re-projected, generalized, and integrated into the existing Federal Lands data set. Newly established wilderness areas were also acquired and integrated into the data set. Eighty-six wilderness areas were added as a result of this effort.
The accuracy of wilderness names was reviewed in cooperation with the Aldo Leopold Wilderness Research Institute. Name changes were made to resolve misspellings or incorrectly named features.
Wilderness area boundaries in Arizona, California, New Mexico, and Colorado were reviewed and, in some cases, re-aligned. Arizona wilderness areas and wilderness study areas managed by the Bureau of Land Management (BLM), the Fish and Wildlife Service, the Forest Service, and National Park Service were reviewed with AZ-WLD90. California wilderness areas managed by the BLM were reviewed using Information the Sacramento office. Colorado wildernesses and wilderness study areas were reviewed with CO-WLD00 and CO-WSA00, respectively. New Mexico wilderness areas were reviewed with NM-WLD97, which includes wilderness areas managed by the BLM, Fish and Wildlife Service, the Forest Service, and the National Park Service.
An inventory of National Wildlife Refuges was conducted to ensure completeness of refuge data. Fifteen new refuges were added using data sets from regional or field offices of the Fish and Wildlife Service. Five additional refuges that meet the minimum mapping resolution of 640 acres could not be included because data were not available.
Military installations were reviewed with respect to base closure data provided by the Department of Defense Environmental Cleanup Office on their website (<http://www.dtic.mil/envirodod/>). Installations that have closed or are scheduled to close have a notation after the installation name; for example: Loring Air Force Base (Closed); Kelly Air Force Base (Scheduled to close).
Several Army Corps of Engineer lakes were reviewed with 1:100,000 scale topographic maps. Approximately 70 shorelines were adjusted.
In 1998, the National Atlas of the United States published a 1:7,500,00 scale map of Federal and Indian Lands. Corrections made in the preparation of this map were incorporated into the Federal Lands polygon data set. Approximately 60 corrections were made. They included name changes, spelling corrections, and addition and deletion of lands.
Several lands were deleted that were incorrectly attributed as Wilderness Study Areas. They are: Book Cliffs Instant Study Area, Utah; Devils Garden Natural Area, California; Blue Range Primitive Area, Arizona; and Joshua Tree National Landmark, Utah.
The two Veterans Administration Hospitals that had been included in the data were deleted. Although they had met the minimum mapping resolution of 640 acres, they were not the largest Veterans Administration in terms of capacity (number of beds). A determination will be made whether or not to include Veterans Administration hospitals prior to the next release of the data.
Digital Line Graph data that had not been complete at the time of the first release were incorporated into the data set.
The attributes were reorganized to better represent multi-coded features. In general, polygons which represent two or more feature classes, where one feature class is contained in another (e.g. a wilderness area inside a forest), have the smaller or 'contained' feature as Feature1 and the larger feature as Feature2. Similarly, the feature referenced as Feature3 will contain the land in Feature2.
Approximately 500 new URL addresses were added to link Federal Land features to agency websites.

In DLG format, files underwent comparison to a graphic source or image source to assess digital positional accuracy. During conversion to Arc/INFO coverage format and the process to append the States together, node snapping and fuzzy tolerances may have caused minimal positional shifts.
This data set includes federal land and Indian reservation polygon features for all 50 of the United States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. The minimum map resolution is 640 acres or one square mile. Generally, features under this size are not shown.
Using ESRI's Arc/INFO GIS software, the data set was checked for label errors, dangling nodes, and intersections. Polygon topology was built for the data set using the BUILD command.
