Refuge Boundary for Sunkhaze Meadows National Wildlife Refuge in MaineEntry ID: USFWS_CSDS_snkbnd
Abstract: This data set contains boundary layers for the Sunkhaze Meadows
National Wildlife Refuge in Maine.
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). A joint effort between the Region 5 (northeast - ME, MA, NH,
VT, RI, CT, NY, PA, NJ, MD, VA, WV) ... GIS Lab and Realty program, has
resulted in digital refuge boundaries for all refuges in the northeast
at a 1:24,000 scale.
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. The Realty
Survey program in USFWS is developing cadastral information (boundary
and acreage data) appropriate for legal purposes. It is expected that
data created in this project will be replaced as better survey
information is collected.
Status maps were registered to geographic coordinates, boundaries
digitized and labeled, then stepped through 3 levels of quality review
for spatial and thematic accuracy. Complete process description can be
found in Service Lands Boundary Data SOP.
Refuge boundaries define areas that are approved by U.S. Congress for
acquisition in the National Wildlife Refuge System, or are currently
owned by USFWS. Arcs are coded with an item "boundary" that the type
of boundary line and polygons are coded with an item "status" that
describes their ownership status.

This description is a member of a collection. The collection is described in
ISO Topic Category
Quality Digital refuge boundaries are plotted for arc and polygon
attributes, and compared to USFWS Realty status maps for coding
accuracy. Three levels of review are conducted (R5 GIS Lab, Realty
Program, Refuge Manager), and are repeated at each step until it
passes error free.
All polygons are closed, and adjusted to the most ... accurate geographic
feature, usually a USGS 7.5' quad. All dangling arcs were removed.
All boundaries were digitized for exterior fee-titled owned lands,
acquired tracts, and approved legislative area. Edit plots are
reviewed for complete digitization.
Digital refuge boundaries are verified against USGS 7.5' DLG data such
as roads, hydrography, or plotted at 1:24,000 scale and overlayed on
USGS 7.5' maps. Data is stored in ArcInfo single precision.
Access Constraints None
Use Constraints Refuge boundary data were compiled for resource applications. It is
inappropriate to use this data in legal situations, or other
applications where spatial error cannot exceed the USGS 7.5' mapping
