Application of High-resolution Satellite Imagery in Water Quality Monitoring of Rivers and Lakes

Abstract

The traditional water quality monitoring needs a lot of manpower and financial resources, but with the advantage of high time efficiency and other advantages of high-score data for information extraction, analysis and monitoring can be timely, large-scale monitoring of specific water, make up for the shortcoming of traditional water quality environmental monitoring. This paper introduces the theoretical method and technical process of monitoring surface water body with high score data. First, the original remote sensing data are preprocessed by radiometric calibration, geometric correction, atmospheric correction and water extraction, and then an inversion model is established to invert the chlorophyll a concentration, and then the main monitoring indicators are established, such as suspended matter, transparency and eutrophication index.
