Series_Information:

Series_Name: National Wildlife Refuge Boundary Data

Issue_Identification: Halfbreed Lake NWR

Description:

Abstract:

National Wildlife Refuges are federal lands managed by the U.S. Fish and Wildlife Service (USFWS). The source for boundary information was 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.

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. While creating the digital boundary of Halfbreed Lake, a discrepancy has been found between the acreage on file in Realty, and that calculated by the software (ArcInfo); the discrepancy may be in the range of 136 acres. It appears further research of Public Land Survey System (PLSS) information will be needed to resolve the question; however, the resolution of the question is outside the scope of this project.

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:

Digital refuge boundary lines were overlain on DRG (USGS 7.5' topo. quads) on screen and compared for accuracy; digital boundary was compared to source material for completeness. 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 digitized. Line work was checked for omissions against original source material. A plot of the digital file was sent to the refuge manager for inspection.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

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

Source_Contribution:

The refuge boundary representation and Public Land Survey System data on the DRG was used to create this coverage. Please see "Use_Constraints" section of this metadata regarding PLSS.

Process_Step:

Process_Description:

Using ArcEdit, portions of the digital boundary were created by screen- digitizing the refuge boundary representation from the DRG; other portions were created by either digitizing PLSS data from the DRG or by using ArcEdit construction methods to create aliquot parts from the digitized PLSS. The projection was defined, and the coverage was built for line and polygon. Arc and polygon items were added and populated.

Overview_Description:

Entity_and_Attribute_Overview: USFWS National Wildlife Refuge Approved Acquisition Boundary

Entity_and_Attribute_Detail_Citation:

An approved acquisition boundary defines an area that is approved for acquisition by the National Wildlife Refuge System, or is currently owned by USFWS. See Service Lands Boundary Data 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 (acreage for the area acquired by USFWS - on file in Realty Office). METHOD (contains codes for data entry method - data source) - Dig-DRG (digitized - Digital Raster Graphics). Arc items in addition to those in the SOP include METHOD (as described for polygon).
