资源简介：

This data view depicts lands and waters administered by the U.S. Fish and Wildlife Service (USFWS) in North America, U.S. Trust Territories and Possessions. It may also include inholdings that are not administered by USFWS. The primary source for this information is the USFWS Realty program. These are resource grade mapping representations of the U.S. Fish and Wildlife Service boundaries. For legal descriptions of the land represented here, contact the USFWS Realty Office. This map layer was compiled by the U.S. Fish and Wildlife Service. Although these boundaries represent lands administered by the U.S. Fish and Wildlife Service, not all areas are open to the public. Some fragile habitats need to be protected from human traffic and some management areas are closed. The public is urged to contact specific Refuges or other conservation areas before visiting.Data can also be downloaded from ServCat, the FWS Catalog.  Go to this link for downloadable cadastral data: <a target='_blank' href='https://iris.fws.gov/APPS/ServCat/SavedSearch/Profile/2674' rel='nofollow ugc noopener noreferrer'>https://iris.fws.gov/APPS/ServCat/SavedSearch/Profile/2674</a>This dataset contains features which have been modified from the source regional data. For select features, geometry has been generalized up to a specified threshold to reduce a high number of vertices in large multipart polygons and improve web service performance. Currently five or fewer features are generalized in each dataset, with the generalization tolerance varying from 1m up to 30m per feature, as required.  To further improve web service performance: OGC geometry problems were automatically fixed where possible, true curves were densified, and the data were projected into the WGS 1984 Web Mercator Auxiliary Sphere projection.Sync is enabled, but editing is disabled. POC for these data are: cdwg@fws.gov
