Abstract :
The new generation polar-orbit meteorological satellite of China-FY3A carries a sensor named medium resolution spectral imager (MERSI), which includes 20 channels to observe the same area 2 to 6 times everyday. Its data with high resolutions of time and spatial are useful for detecting water. In this paper, we analyze the data by histogram and clustering, get the characters of all channels. We summarize two methods of detecting water bodies and compare the results of them. The test indicates that extracting water bodies with NDI is better.
