| Abstract: | The current application of flood disaster monitoring technique based on remote sensing in China was analyzed and the limitation of insufficiency and un-real time response was pointed out. After introduced the characteristics of MODIS and compared with that of NOAA-AVHRR,a flood disaster monitoring and assessing system based on MODIS and GIS was proposed and designed. By using free and higher temporal resolution MODIS data, a software based on GIS technique was developed to monitor different types of land use inundated area in real time in the specific region,and provide quick and reliable basis for dynamic monitoring and assessing of flood. |
