Description:

Abstract:

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.

Purpose:

The intended application of the 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.

Supplemental_Information:

Data are available both in the UTM projection described herein, and in geographic coordinates.

Research of USFWS Region 6 files. Also based on decisions regarding the location of the boundary made at a meeting to discuss the boundary held at the Regional Office on June 21, 2001.

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 standards. This data is specifically not intended to be used as a land survey or representation of land for conveyance or tax purposes. An approved acquisition boundary delineates an area that has been approved for inclusion into a National Wildlife Refuge. However approval does not necessarily indicate that the entire area inside this boundary has been (or ever will be) acquired by U.S. Fish and Wildlife Service.

Native_Data_Set_Environment:

Refuge data were developed with ESRI's ArcInfo version 7.2.1 Patch 2 software on a PC running WINDOWS NT version 4.0 (Build 1381: Service Pack 6) operating system.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Arc and polygon item values are rechecked by data entry staff for omissions and against the original data for accuracy.

Logical_Consistency_Report:

For portions of the boundary that were input from survey data, the input was captured in the watch file and compared to source material for accuracy and completeness. Line work for the remaining portions of the digital boundary was compared to source material to check for accuracy and completeness. Digital refuge boundary lines were overlain on a DRG (USGS 7.5' digital topographical quadrangles) to check for general spatial relationships. Software capabilities were used to ensure arcs have no dangling nodes and intersection errors and to check polygons for label errors.

Completeness_Report:

Arcs that represent the entire approved acquisition boundary were created. Line- work was checked for omissions against the source material.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Digital boundary was overlain on USGS 7.5' minute topo. quad(s) (DRG) to determine general spatial positioning. Data are stored in ArcInfo double precision.

Process_Step:

Process_Description:

Line work was added to an empty ArcInfo double precision coverage by a combination of the following: survey data input using ArcInfo COGO and starting points obtained from the DRG; screen-digitizing features from DOQs and the DRG using ArcEdit, also digitizing Public Land Survey information (from DRG) and using ArcEdit construction commands to create aliquots parts; snapping to points in coverages created from GPS point data. Arc and polygon items were added and populated. The coverage projection was defined and built as a network coverage.

Overview_Description:

Entity_and_Attribute_Overview: USFWS National Wildlife Refuge Approved Acquisition Boundary

Entity_and_Attribute_Detail_Citation:

An approved acquisition boundary as it applies to Region 6 and to the digital legislative boundary set forth in 97-01 U. S. Fish and Wildlife Service Lands Boundary Data (SOP) is defined as an area that is approved for acquisition into a National Wildlife Refuge; it may also include lands that have been acquired by fee, lease, easement, or agreement. See SOP under "Labeling Files and Geographic Features - Legislative Boundary" (in process 1) for information on arc and polygon items and item values. Polygon items in addition to those referenced in the SOP include: ARC_ACRES (replaces SOP ACREAGE item); REC_ACRES and METHOD (these two items are no longer considered applicable, and therefore are not populated; however, the items are being retained to maintain consistency with coverages created previously that contain these items). The arc attribute table also contains an item named METHOD (not in the SOP) which is not populated.
