Spatiotemporal Prediction of Urban Land Subsidence Using ConvLSTM Enhanced with Spatial Attention Mechanism

Rapid urbanization has increasingly posed risks of inducing land subsidence in newly developed urban districts, posing growing threats to infrastructure safety. This study focuses on a selected rectangular area within the Shannan New District of Huainan City. Based on 94 Sentinel...

A method for intelligent recognition and multi-parameter inversion of photovoltaic panels based on UAV-LiDAR point clouds and DGRNet

Addressing the shortcomings of existing monitoring methods for mountainous photovoltaic power plants—including insufficient 3D data acquisition, low levels of automation, and point cloud recognition methods that are poorly adapted to mountainous scenarios, lack systematic compari...

A robust adaptive InSAR-GNSS fusion approach for three-dimensional surface deformation monitoring

Urban land subsidence threatens coastal infrastructure, especially in reclaimed and densely developed areas. Single-geometry InSAR (Interferometric Synthetic Aperture Radar) provides wide-area LOS (line-of-sight) deformation but is limited in resolving 3D (three-dimensional) grou...
