    Impervious Surface Area Classification of Twin Cities Metropolitan Area, 2000

    Metadata Updated: November 10, 2020

    Landsat TM data have been used to map the percentage of impervious surface area of the seven-county TCMA for the year 2000. Impervious surfaces are defined as areas impenetrable by water– including roads, rooftops, sidewalks and parking lots. The coverage provides information on the percentage of impervious surface on a 30-m pixel basis for all urban areas. The impervious surface layer was derived from a single date of Landsat-5 TM data. Following the classification of land cover types, a regression model relating percent impervious surface area to Landsat TM greenness values was used to estimate the percent impervious surface area for pixels classified as urban or developed. Classification of the Landsat TM data provides a means to map and quantify the degree of impervious surface area, an indicator of environmental quality, over large geographic areas and over time.
