Monitoring of soil erosion caused by construction projects using remote sensing images

Abstract

The application of Remote Sensing (RS) images to soil erosion monitoring caused by construction projects can meet the needs of dynamic supervision and early warning, and can also significantly improve the efficiency of supervision. In this paper, a technical process for monitoring soil erosion caused by construction projects was proposed. As an example, the high-definition RS survey of the whole city of Zhoushan was carried out. Firstly, the contour lines of the protection range determined during the approval of the construction project were vectorized. Secondly, RS interpretation of perturbation patches of construction projects was carried out with the aid of interpretation marks. Thirdly, preliminary judgment of perturbation compliance was made through the spatial overlay of the interpretation results and approved prevention scope. Finally, field investigation was done to correct the results of RS image analysis. The results show that this technical process can interpret the activity status of construction projects, effectively determine the compliance of perturbation conditions, and improve the efficiency of soil-water conservation supervision.
