Why was the data set created?

Coverage is intended to be used as cartographic representation of Voyageurs National Park boundary.


How was the data set created?

  1. From what previous works were the data drawn?

    D7.5 (source 1 of 3)
    National Mapping Division U.S. Geological Survey, 19860101, 1:24000 scale 7.5 minute quadrangle: U.S. Geological Survey, Reston, VA.

    Type_of_Source_Media: paper
    Source_Scale_Denominator: 24000
    Source_Contribution:
    Small area was table-digitized from quad near Rainy Lake Visitor Center.

    GPS (source 2 of 3)
    Samuel R. Lammie, Voyageurs National Park, Unpublished material, NPS-1 Boundary Corridor: Not Applicable, Not Applicable.

    Other_Citation_Details:
    Boundary corridor identified by collecting GPS field data and buffering resultant centerline.
    Type_of_Source_Media: digital file
    Source_Scale_Denominator: 12000
    Source_Contribution:
    Collected autonomous GPS data using Trimble XL Pathfinder GPS. Data represented new road centerline. Differentially corrected data to improve accuracies. Buffered corrected data by 400 feet to identify park boundary along road.

    USGS SPM (source 3 of 3)
    U.S. Geological Survey, 19790101, 1979 Special USGS Park Map: U.S. Geological Survey, Reston, VA.

    Other_Citation_Details:
    Special park map at 1:50000 scale was scanned using large format scanner at WASO GIS in Denver, CO on 9/15/1992.
    Type_of_Source_Media: digital image
    Source_Scale_Denominator: 50000
    Source_Contribution:
    Park boundary was heads-up digitized. Since source data was prior to construction of Rainy Lake Visitor Center and prior to construction of NPS-1, other methods were required to acquire data in those areas.

  2. How were the data generated, processed, and modified?

    Date: 15-Nov-1992 (process 1 of 5)
    Heads-up digitized park boundary using GIS software GRASS Version 4.1 and utilizing scanned park map (DRG) as raster backdrop. Subsequently, exported to PC ArcInfo as DXF files. Imported into PC ArcInfo using DXFARC command.
