Thus, even though the spatial resolution is almost the same level, a digital aerial camera can capture much clearer images of the earth surface than a film camera does. This paper highlights the capability of digital aerial images in detecting various damages due to earthquakes. In the recent earthquakes in Japan, such as the 2004 Mid-Niigata earthquake and the 2007 Off-Mid-Niigata earthquake, the affected areas were captured by digital aerial cameras as well as by analog aerial cameras and high-resolution satellites. In this paper, the quality of digital aerial images is first compared with scanned analog photos. Then the digital aerial images taken before and after the 2007 Off-Mid-Niigata earthquake are used to detect building damage. Both the pixel-based classification and the object-based classification are conducted. Debris of collapsed buildings is extracted correctly from the digital image processing.
