Summary
Abstract: This data set contains boundary layers for the Concord Division of
the Great Meadows National Wildlife Refuge.

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 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.

Quality
Digital refuge boundaries are plotted with arc and polygon
attributes, then compared to USFWS Realty status maps, survey
documents, and collateral information for coding accuracy. Three
levels of quality-control review are conducted (Cartography and
Spatial Data Services, Realty Management Branch, Refuge Staff) with
corrections being incorporated after each review until the dataset is
deemed error-free.

All polygons are closed and adjusted to the most accurate geographic
features, usually on a USGS 7.5' topographic quad. All dangling
arcs,undershoots, and overshoots have been removed.

All boundaries were digitized for exterior fee-titled, USFWS owned
lands, acquired tracts, and areas approved for USFWS
acquisition. Plots are generated and quality-control reviewed for
omission and commission digitizing errors.

Digital refuge boundaries are verified against USGS
1:24,000-scale,7.5' DLG, DRG, or 1:12,000-scale DOQQ data such as
roads,hydrography, or plotted at 1:24,000 scale and overlayed on USGS
7.5' maps. Data are stored in ArcInfo double precision.


Access Constraints
None


Use Constraints
Refuge boundary data were compiled for resource applications. It is
inappropriate to use these data in legal situations, or other
applications where spatial error cannot exceed the USGS 7.5-minute
mapping standards.
