  Description:
    Abstract:
      The WISCLAND (Wisconsin Initiative for Statewide Cooperation on
      Landscape Analysis and Data) Land Cover data set is a raster
      representation of vegetation/land cover for the state of
      Wisconsin.  The source data were acquired from the nationwide MRLC
      (Multi-Resolution Land Characteristics Consortium) acquisition of
      dual-date Landsat Thematic Mapper (TM) data primarily from 1992.
      The image processing technique followed was published in the UMGAP
      Image Processing Protocol (1998).  The original pixel size of the
      source TM data is 30 meters, however the classified WISCLAND Land
      Cover data (excluding URBAN) are generalized or 'smoothed' to an
      area no smaller than four contiguous pixels (equivalent to
      approximately one acre).  The result of this smoothing is that any
      feature five acres or larger may be resolved in the data (i.e.,
      Minimum Mapping Unit (MMU) of five acres).  The Land Cover data
      are usable at nominal scales of 1:40,000 to 1:500,000 for a wide
      variety of resource management and planning applications.  The
      classification scheme was designed to be compatible with existing
      classification schemes such as UNESCO's and Anderson's.
    Purpose:
      These data can be used for landscape scale analysis in various
      disciplines such as wildlife ecology, forestry, or land use
      planning.  The data have been developed for inclusion in the Gap
      Analysis Program.  The data should be used at a scale of at least
      1:40,000.  It is also suggested that the data be used at no less
      than the five acre MMU.
    Supplemental_Information:
      The spatial extent of this data layer is the state of Wisconsin.
      Extensive additional information about this data set is provided 
      in the 'Land Cover of Wisconsin, User's Guide to WISCLAND Land 
      Cover Data', 1999, WiDNR, accessible at:

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report:
      Accuracy Assessment matrices have been completed for each
      classification unit of the dataset, or 'SCCU' (Spectrally
      Consistent Classification Unit).  These matrices should be
      referred to when using the WISCLAND Land Cover Data, and are
      included as MS Excel spreadsheets.  Accuracy Assessment was
      calculated separately for wetlands and uplands.  With uplands,
      errors of omission and commission (both at species level, and
      generalized level) have been tallied for each classification unit
      or 'SCCU', including an overall percentage of accuracy, and a 
      K-hat statistic.  Wetlands accuracy was also based on the
      classification unit, with percentage User's accuracy for each
      class and an overall percentage accuracy.  Urban accuracy
      assessment was performed on its unit of classification, the full
      TM scene.  Both User's and an overall accuracy assessment are
      given.

  Logical_Consistency_Report:
    Because of the 8-bit file structure used for the WISCLAND Land Cover
    data, the ERDAS software prevents the assignment of invalid pixel
    values outside of a 0-to-256 range.  In addition, the data have
    undergone visual, on-screen review by members of the WiDNR/GEO Land
    Cover development team to check for classification errors or other
    anomalies.

  Completeness_Report:
    A stratified random sampling technique was used to identify 'ground
    truthing' points for the purpose of land cover classification and
    accuracy assessment, as described in the WISCLAND Land Cover
    Protocol.  A 'Lineage' document (see Supplemental Information above)
    lists the final land cover classifications, and classes omitted, 
    for each processing SCCU.

  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:
        The source nationwide MRLC (Multi-Resolution Land
        Characteristics Consortium) data were geometrically corrected by
        EROS Data Center to 1:24,000 scale USGS topographic quadrangle
        maps.  Accuracy standards were on the order of RMS error no
        greater than 1 pixel.  The WISCLAND Land Cover data are
        considered to reflect the stated positional accuracy of the
        source MRLC data set, with positional error of no more than plus
        or minus 1 pixel (30 meters).

    Process_Step:
      Process_Description:
        The geo-rectified MRLC data were processed according to the
        protocol published in the UMGAP Image Processing Protocol
        (1998), found at http://www.emtc.nbs.gov/umgaphome.html.
        The classified data (except URBAN) were generalized from their
        original 30-meter resolution to a one acre area of any four
        contiguous like pixels using a clump-sieve-fill algorithm 
        devised within Imagine and described in detail within the 
        in-house technical procedures document.  Strata were clipped at
        the SCCU boundary, converted from Imagine v.8.3 files into
        ARC/INFO Grids, projected into WTM NAD83 with adjustment for 91,
        and then joined for continuous coverage.

Entity_and_Attribute_Information:
  Overview_Description:
    Entity_and_Attribute_Overview:
      Each pixel within the WISCLAND Land Cover raster dataset has an
      associated 8-bit value which corresponds to a Land Cover class.
      The WISCLAND Land Cover classification scheme is a hierarchical
      scheme which is modeled after Anderson's Classification scheme
      (USGS, 1976) but adaptable to other existing classification
      schemes, especially the UNESCO/The Nature Conservancy
      classification system.
    Entity_and_Attribute_Detail_Citation:
      WISCLAND LAND COVER CLASSIFICATION SCHEME -
      Numbers in parentheses are the numeric class values assigned to 
      pixels.  The 3-level hierarchy is indicated by decimal values and
      indentation.  Gaps in the numeric and hierarchical sequence are due
      to entries in the 'extended' classification which were not part of
      the final WISCLAND classification scheme. 
      (For a complete explanation of the WISCLAND Land Cover
      classification scheme, refer to the User's Guide cited in the
