In this report we compare the damaged areas by an earthquake detected by using image processsing from aereal photographs with the actual damage data, to evaluate the performance of image processing algorithm used. For comparison, we used a GIS (Geographic Information System), which can manage and analyze spatial information systematically. The algorithm to be evaluated is the one using color information and edge information to identify the damaged areas by an earthquake, proposed by the authors. As a result, a significant portion of burnt-out areas can be detected by the algorithm, thresholding the detected connected regions by their sizes. A possibility of detecting areas of totally damaged houses is also shown.
