Study on Monitoring Water Surface in Poyang Lake by MODIS Image

Article Preview

Abstract:

. In the paper, we use med-resolution image data-MODIS to monitor Poyang Lake water surface. The resolution of images is 250 meters. The cycle of the monitoring frequence is 8 days. The monitoring time is from Jan, 1st to June, 25th, 2012. We select water surface in the embankment of Poyang Lake as the research object. The results show that Modis image can extracte water surface information quickly for water monitoring in time. The technology can be supplied to trail the change of Poyang Lake eco-system frequently.
