- Abstract:
- An M 7.3 strong earthquake occurred in Port-au-Prince,Haiti on Jan. 12, 2010 has destroyed a large number of buildings.From the post-earthquake very high resolution remote sensing image, we can find there are a lot of rubbles around collapsed and partly damaged buildings. Therefore, we take these rubbles as seismic-damage characteristics of the collapsed buildings and use the following three methods—pixel-based method, object-oriented method and object-oriented method combined with geo-statistical texture to extract rubbles automatically. Finally, we assess the accuracy of the three classifications of the remotely-sensed data through the three methods. It turns out that the accuracy of pixel-based method is less than that of object-oriented method. The overall Kappa coefficient and user's precision of rubbles have improved remarkably when adding texture feature. However, there is no obvious improvement of the producer precision of the rubbles.
