Application of Satellite Remote Sensing Technology in River Monitoring and Governance

Abstract

According With the development of space remote sensing technology, the emergence of various multi-temporal, multi-spectral, hyperspectral, high-resolution remote sensing image technologies and corresponding products makes the information of the earth’s surface resources and topography more quickly and effectively presented, which not only provides a lot of information, but also provides abundant information for accurate and scientific geological prediction. Compared with the middle and low-resolution remote sensing image, the high-resolution target image has clearer contour and richer spatial details. For a long time, the monitoring and analysis of river course changes and environmental evolution in river basins has been lacking effective automatic and intelligent analysis tools to solve large spatial and time-span problems. By combining with high resolution satellite remote sensing technology, making full use of the spatial and temporal advantages of high resolution satellite remote sensing image information, automatic identification and analysis of the evolution of river course and surrounding environment in the basin, timely discovery of existing problems and analysis of the effect of river course management can effectively support the scientific research and decision-making support for River Basin management. It provides a new idea for the wide application of water resources industry in river basin monitoring and control. In this paper, the development of satellite remote sensing system, high resolution satellite remote sensing image analysis, main analysis methods and related application results are introduced. The application and Prospect of satellite remote sensing technology in river monitoring and harnessing are briefly described.
