A preliminary study on searching key rescue targetafter mainshock based on high-resolutionremote sensing image

With the development of high-resolution satellite technology, lots of remote sensing data were applied to disaster assessment and relief. Based on the study on prioritizing search and rescue target using remote sensing image recognition, this paper described a way of how to select collapsed buildings from an earthquake affected area for search and rescue based on high-resolution remote sensing data analysis, including the rules and analysis flow. An example was given with the data acquried during the 2008 Wenchuan earthquake to discuss the analysis models detailedly.
