Frequently anticipated questions:


What does this data set describe?

Title: Wilderness Study Area - Central Arctic Management Area (CAMA)
Abstract:
This is a line, polygon and region coverage of the Central Arctic Management Area (CAMA) Wilderness Study Area. These boundaries were digitally created in response to IM 2000-040. Boundaries were determined using a combination of master title plats, CAMA Final Environmental Impact Statement, ANILCA sec. 1001 (a), and general land status coverage of Alaska. Boundaries were digitized on screen using USGS 15' series Digital Raster Graphic as a base map.

      Planar coordinates are encoded using coordinate pair
      Abscissae (x-coordinates) are specified to the nearest 0.000001
      Ordinates (y-coordinates) are specified to the nearest 0.000001
      Planar coordinates are specified in meters

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

Why was the data set created?

This dataset was generated in response to IM 2000-040, to depict those areas defined as Wilderness Study Areas (WSAs) within Alaska. It is just a portion of a nationwide effort to assemble all WSAs and Wilderness areas into a single National Landscape Conservation System coverage.
Please consult BLM-Alaska's Land Information System for the Legal Land Descriptions for each of the Wilderness Study Areas.


How was the data set created?

  1. From what previous works were the data drawn?

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

    Date: 21-Jul-2000 (process 1 of 1)
    Legal boundary originally determined from the CAMA EIS and hand drawn on 15' series quad maps. MTPs were consulted to ensure proper BLM lands were properly identified. The boundary was digitized on screen using DRGs as backdrop to duplicate lines drawn on quad maps.

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Attributes checked against BLM-Alaska's Land Information System

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This dataset was originally created in July 2000 (based on the land status at that time). It was modified in June 2003 to reflect the landstatus changes which occured between 2000 and 2003.

  5. How consistent are the relationships among the observations, including topology?

    Logical errors were identified using ArcInfo LABELERRORS and NODEERRORS commands in July 2000 after the initial dataset was created. Polygons were closed and dangling nodes were removed.
    Polygon topology exists.


How can someone get a copy of the data set?
