Abstract
This Grid-format data set, known as WISCLAND Land Cover, is a raster representation of land cover of Wisconsin derived from Landsat satellite imagery. 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 scales smaller than 1:40,000. It is also suggested that the data be used at no less than the five acre minimum mapping unit. ArcView with the Spatial Analyst Extension, ArcInfo/ArcGIS Grid, or comparable GIS software is needed to use the Grid format data meaningfully.
Supplemental Information
Extensive additional information about this data set, including data lineage information, is provided in the 'Land Cover of Wisconsin, User's Guide to WISCLAND Land Cover Data', 1999, WiDNR. The WISCLAND User's Guide is accessible at: URL:ftp://dnrftp01.wi.gov/geodata/metadata/wilndcov.pdf "WISCLAND" is the Wisconsin Initiative for Statewide Cooperation on Landscape Analysis and Data.

Description
The geo-rectified MRLC data were processed according to the protocol published in the UMGAP Image Processing Protocol (1998), found at: http://www.umesc.usgs.gov/umgap/documents.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 ArcInfo Grids, projected into WTM83/91, and then joined for continuous coverage.
