The purpose of tills study is to develop a method for estimating the quantity of buildings with different seismic vulnerability according to GESI method in developing countries. At first we selected a learning area with the 25m gridded DCONOS imagery data of Marikina City, Metro Manila, Philippines. Based on the cluster analysis for the distribution patterns of DNs available in me learning area, we proposed a method to categorize the grids into 7 different land cover pattern. Then we developed a procedure of field investigation using digital video camera with GPS to identify die quantity of buildings with different seismic vulnerability. Finally, we estimated the quantity of buildings with different seismic vulnerability at the entire Marikina City area.
