Application of remote sensing technology in river construction project monitoring

It is a laborious and time-consuming work to inspect the river-related construction projects manually, which is difficult to meet the increasing application demands of frequent monitoring of the river-related construction projects. In this paper, the automatic running process, including satellite remote sensing image processing, thematic mapping and report preparation, is built based on Python language. The process has been used to track, monitor and analyze 43 riverrelated construction projects in Xijiang Basin of Guangdong Province since January 2015. With regard to the key riverrelated construction projects, the UAV (Unmanned Aerial Vehicle) remote sensing technology is used to construct 3D model and measure the engineering characteristic parameters. By selecting typical river-related construction project and analyzing remote monitoring data of satellite and UAV, results show that river-related construction projects monitoring can be effectively realized by using the characteristics of multi-temporal dynamic monitoring of satellite remote sensing and high spatial resolution of UAV remote sensing. It is effective by using satellite and UAV remote sensing technology in monitoring river-related construction projects, which can objectively reflect the progress of river-related construction projects, obtain quantitative information, and improve the accuracy, efficiency, timeliness and reliability of water administration supervision.
