本研究旨在评估卫星图像在估算城市化地区不透水面积百分比方面的适用性。提出了两种估计方法并将其应用于日本的小型城市化流域。该区域在两种不同的细分情况下被考虑；即14区和17区。对1984年的LANDSAT-MSS（多光谱扫描仪）、1988年的MOS-MESSR（多光谱电子自扫描辐射计）和1988年的SPOT-HRV（高分辨率可见光）卫星图像进行了分类。利用这些分类结果估算了 17 个区域的不透水百分比。将这些值与从航空照片中获得的值进行比较。从图像中得出的不透水性百分比与从航空照片中得出的不透水性百分比非常吻合。评估的估计误差小于10%，与航空照片获得的估计误差相同。
This study aims to evaluate the applicability of satellite imagery in estimating the percentage of impervious area in urbanized areas. Two methods of estimation are proposed and applied to a small urbanized watershed in Japan. The area is considered under two different cases of subdivision; i.e., 14 zones and 17 zones. The satellite imageries of LANDSAT-MSS (Multi-Spectral Scanner) in 1984, MOS-MESSR(Multi-spectral Electronic Self-Scanning Radiometer) in 1988 and SPOT-HRV(High Resolution Visible) in 1988 are classified. The percentage of imperviousness in 17 zones is estimated by using these classification results. These values are compared with the ones obtained from the aerial photographs. The percent imperviousness derived from the imagery agrees well with those derived from aerial photographs. The estimation errors evaluated are less than 10%, the same as those obtained from aerial photographs.
