The Research on the Method of Extracting Water Body Information from Small Satellite Images

摘要：

Extraction water information from remotely sensed is significant for surveying, planning and protecting water resources. Firstly, the special band (PRWI) was applied to extract water information. Secondly, water body information was extracted by decision tree. Finally, the results were checked by visual and statistical accuracy assessment. Through indicated in the plain experiment, this method gets satisfied result. However, some pixels in the neighborhood between water bodies and mulberry are judged by mistakes. The experiment in mountainous area shows that it can get satisfied results in small satellite images and TM/ETM images by the same method. The small satellite can be used in dynamic monitor such as urban planning, ecological environment, land utilization,environmental disaster and so on. The Small Satellite will be served in Beijing Olympic 2008.
