  Description:
    Abstract:
      This land cover data set was produced as part of a
      cooperative project between the U.S. Geological Survey
      (USGS) and the U.S. Environmental Protection Agency 
      (USEPA) to produce a consistent, land cover data layer
      for the conterminous U.S. based on 30-meter Landsat
      thematic mapper (TM) data. National Land Cover Data 
      (NLCD) was developed from TM data acquired by the 
      Multi-resoultion Land Characterization (MRLC) Consortium.
      The MRLC Consortium is a partnership of federal agencies
      that produce or use land cover data. Partners include the
      USGS (National Mapping, Biological Resources, and Water 
      Resources Divisions), USEPA, the U.S. Forest Service, and
      the National Oceanic and Atmospheric Administration.
    Purpose:
      Oregon Geodata Browser Web Site.
    Supplemental_Information:
      The Oregon NLCD set was produced as part of a project area
      encompassing portions of Federal Region X, including the
      states of Idaho, Oregon, and Washington. This data set was 
      produced under the direction of the MRLC Regional Land Cover 
      Characterization Project of the USGS EROS Data Center (EDC), 
      Sioux Falls, SD. Questions about the data set can be 
      directed to the MRLC Regional Team at (605) 594-6114 or
      mrlc@edcmail.cr.usgs.gov.

            Caveats and Concerns:
            1) Both irrigated and dryland agriculture are practiced in
            this region. In the dryland areas small grains predominate;
            fields are classified as fallow when there is no evidence of
            visible vegetation indicating a prescribed alternation 
            between cropping and tillage. Crop types in the irrigated
            areas were difficult to reliably distinguish; row crops are 
            likely to be under represented where no field observations 
            or other ancillary information was incorporated.
