ICESat-2数据在煤矿塌陷区水深测量中的应用
Application of ICESat-2 data in water depth measurement of coal mine subsidence areas
摘要
Abstract
Traditional ground-based water depth measurements often require substantial human,material,and time resources,especially in coal mine subsidence areas,where the task becomes particularly challenging.The satellite data from Ice,Cloud,and land Elevation Satellite 2(ICESat-2)offers significant advantages in terms of wide coverage and high effi-ciency,making it suitable for areas that are difficult to access due to complex terrain.This efficient,non-contact measure-ment method provides a convenient solution for monitoring coal mine subsidence zones.This study focuses on the water area of a coal mine subsidence area in Jining,Shandong Province,using the adaptive density-based spatial clustering for applica-tions with noise(DBSCAN)algorithm to denoise the ICESat-2 signals,resulting in a linear distribution of water depth points.The results show that there is a high degree of consistency between the water depth data measured by unmanned boats and the water depth values derived from the ICESat-2 light detection and ranging(LiDAR)data,with a coefficient of deter-mination R2 of 0.98 and a root mean square error RMSE of 0.68 m.关键词
