Susquehanna National Wildlife Refuge in Maryland
Listed in NASA Earthdata CMR
This data set contains boundary layers for the Susquehanna National Wildlife Refuge in Maryland.
Description
National Wildlife Refuges are federal lands managed by the U.S. Fish and Wildlife Service (USFWS). The primary source for boundary information is the USFWS Realty program (status maps, legal surveys).
An effort by the USFWS Region 5 (northeast states - ME,NH,VT, MA, RI, CT, NY, PA, NJ, MD, DE, WV, VA) Realty Division, Cartography and Spatial Data Services Branch has resulted in digital refuge boundaries for all refuges in the northeast at a scale of 1:24,000. The purpose of this data is to serve as a spatial reference of refuge boundaries for 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.

Status maps were registered to geographic coordinates, boundaries were digitized and labeled. Digital files were updated using survey and collateral data, then stepped through 3 levels of quality-control review for spatial and thematic accuracy. Refuge boundaries define areas that are approved by the U.S. Congress for acquisition into the National Wildlife Refuge System, or are currently owned by USFWS.
Arcs are coded with an item "boundary"with the type of boundary line; polygons are coded with an item "status" that describes their ownership status. [Summary provided by U.S. Fish & Wildlife Service]
