Title: Refuge Boundary for Half-way Lake National Wildlife Refuge
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 (status maps, legal surveys) and county records (deeds and legal surveys).
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. 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.

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.
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 5) 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 and 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 legislative boundary were digitized. Line work was checked for omissions. A plot of the digital file was sent to the refuge manager for inspection and comments.
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: Section lines for section 20 were digitized from the DRG.
Process_Step:
Process_Description:
Processing DRGs: Using ArcInfo software, the collar was clipped from each U.S.G.S. 7.5 minute topographical quadrangle (in DRG format) covering the refuge. For refuges covering more than one quadrangle, individual clipped DRGs are merged. Creating the Refuge Boundary: Using ArcInfo, an empty double precision coverage was created. The DRG was used as a background image from which to screen-digitize section lines for section 20; Arcedit construction methods were used to create certain aliquot parts from the section lines, and refuge boundary lines were selected from the appropriate aliquot lines. The projection was defined, and the coverage was built for line and polygon. Arc and polygon items were added and populated.

Entity_and_Attribute_Detail_Citation:
A "legislative" refuge 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 entire refuge - on file in Realty Office). METHOD (data entry method - data source) e.g. dig-DRG (i.e.digitized - Digital Raster Graphics). Arc items in addition to those in the SOP include METHOD (as described for polygon).
