    Description

    Consider the following example of an accuracy assessment. Landsat data are used to build a thematic map of land cover for a multicounty region. The map classifier (e.g., a supervised classification algorithm) assigns each pixel into one category of land cover. The classification system includes 12 different types of forest and land cover: black spruce, balsam fir, white-cedar, other softwoods, aspen, birch, other hardwoods, urban, wetland, water, pasture, and agriculture. The accuracy of the map must be known by a user of the map to conduct credible analyses.
