Title: Refuge Boundary for Bowdoin 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 executive order 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:
Deeds and other documents and maps were used to determine the current extent of the legislative refuge boundary. DRGs were used for digitizing the boundary. GCDB was used as a source for certain line lengths in T. 31 N. R. 32 E. sec. 33 to assist in construction of part of that section (refer to .aat item named "METHOD" with a value containing "GCDB" for arcs that are influenced by values from GCDB).
Process_Step:
Process_Description:
Using ArcInfo, an empty double precision coverage was created. The refuge boundary was screen digitized over a background image (DRG of U.S.G.S. 7.5' topo. quad(s)). NOTE: A portion of the boundary in section 22 (T. 31 N. R. 31 E.) and section 33 (T. 31 N. R. 32 E.) was determined not to match the boundary as depicted on the DRG. Using the DRG and information from GCDB, Arcedit construction methods were used for this portion of section 33. See "Source Contribution" above for the contribution of GCDB to the boundary. 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); GCDB = Bureau of Land Management's Geographic Coordinate Data Base. Arc items in addition to those in the SOP include METHOD (as described for polygon).
