Estimating Urban Impervious Surface Percent Using Boosting as a Refinement of CART Analysis

    Graphical Abstract
    • Abstract
  • An approach for estimating urban imperviousness surface percent(ISP) through the synergistic use of Landsat ETM+ and high-resolution imagery is presented.In the proposed approach,the ensemble leaning of CART analysis based on Boosting is utilized to construct the ISP predict model,furthermore,to obtain the subpixel ISP results at 30 m resolution.The experiment shows this approach yields ISP estimation performance compared to that of the traditional estimation method based on single CART,and its correlation coefficient of predicted versus actual ISP reaches 0.91 with an average error 11.16%.
