This data layer depicts the external boundaries of lands and waters that are approved for acquisition by the U.S. Fish and Wildlife Service (USFWS) in North America, U.S. Trust Territories and Possessions. The primary source for this information is the USFWS Realty program.
The intended application of this data layer is as a cadastral framework for use with other data layers in GIS and mapping applications. It is specifically not intended to be used as a land survey or representation of land for conveyance or tax purposes.
The FwsApproved feature class is an aggregated data layer derived by appending separate regional feature data sets into a single national set. The spatial and positional accuracy of this information will vary depending on the original source data and methods utilized. Data sources are not listed in this document but are maintained for each region and can be requested. We strive to improve the accuracy of this data and incorporate more reliable information when available.

Up to three levels of quality-control review are conducted with corrections being incorporated after each review until the dataset is deemed acceptable. FwsApproved utilizes coded domains to limit coding errors.
Polygons are closed and adjusted to the most accurate geographic features, usually on a USGS 7.5' topographic quad.
FwsInterest is a dynamic data layer, updates and revisions are ongoing.
This data layer has been verified against USGS 1:24,000-scale and 1:63,360-scale Digital Raster Graphics (DRGs) or 1:12,000-scale Digital Orthophoto Quarter Quads (DOQQs) where available. For some areas not covered by USGS, nautical charts from the National Oceanic and Atmospheric Administration are used.
