Study on Dynamic Monitoring Technology of Soil and Water Conservation in Construction Projects using Multi-source Remote Sensing Information

Abstract

It is the legal duty of water administrative departments to monitor and supervise construction projects, but the single image source and interpretation technology have stunted supervision efficiency improvement. By utilizing the characteristics and advantages of multi-source remote sensing information, we constructed dynamic monitoring technology of soil and water conservation in construction projects based on multi-source remote sensing data, and used Mi Zhi County and Zi Zhou County in Yu Lin City as the experimental area to extract new disturbance maps from 2017 to 2018. The results show that coordinated application of multi-source remote sensing information can effectively improve the monitoring frequency up 64%, and the accuracy up 25%, which can provide reference for the informatization of soil and water conservation supervision in construction projects.
