Method for realizing water area shoreline dynamic monitoring by utilizing high-resolution remote sensing technology

Abstract

The invention discloses a method for realizing water area shoreline dynamic monitoring by using a high-resolution remote sensing technology, which comprises the following steps: S1, river and lake demarcation result collection and arrangement: focusing on collecting river channel management range vector data and taking a sky map as a base map. The invention relates to the technical field of remotesensing science. According to the method for realizing dynamic monitoring of the water area shoreline by utilizing the high-resolution remote sensing technology, aiming at a large-area river and lakewater system and a complex river and lake environment, the high-resolution remote sensing technology has the advantages of high spatial resolution, rich information amount, wide monitoring range, short coverage period, low acquisition cost and convenience in long-term dynamic monitoring. According to the method, high-resolution remote sensing data is preprocessed to obtain an orthoimage base mapcovering rivers and lakes, and illegal information such as river channel invasion, lake reclamation, illegal sand mining and the like are identified and extracted by combining a water area shoreline demarcation management range and utilizing an artificial visual interpretation and on-site review method. Comprehensive supervision of river and lake illegal information and dynamic tracking of rectification effect are realized.

Description

technical field [0001] The invention relates to the field of remote sensing science and technology, in particular to a method for realizing dynamic monitoring of water coastlines by utilizing high-resolution remote sensing technology. Background technique [0002] Remote sensing technology is a detection technology that emerged in the 1960s. Based on the theory of electromagnetic waves, various sensing instruments are used to collect, process, and finally image the electromagnetic wave information radiated and reflected by long-distance targets. It is a comprehensive technology for detecting and identifying various scenes. Through remote sensing technology, domestic high-resolution remote sensing images such as Gaofen-1, Gaofen-2, and Ziyuan-3 can be queried. [0003] The economy continues to grow, the industrialization and urbanization process is accelerated, and the requirements for the utilization of river and lake shorelines are getting higher and higher. The traditional...
