航空写真を用いた兵庫県南部地震における建物被害の目視判読

抄録

Building damage due to the 1995 Kobe Earthquake was extracted using aerial photographs. The result was compared with that of ground surveys to examine the applicability of aerial photo-interpretation. It was recognized that the damage interpretation using aerial photographs for the area of wooden buildings is effective for identifying "collapse'' and 'Iseveredamage''. It is particularly effective in identifying collapsed buildings, since the difference in the results due to different interpretation methods and that due to different interpreters were small. Since the aerial photographs were taken at an right angle to the ground surface, the recognition of minor damage and damage to side walls and columns was difficult.
