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. |
