DBCF: Classification and Understory Terrain Estimation of High-Precision ICESat-2 Photon Point Clouds

In understory terrain studies, high-precision photon point cloud classification is essential for the comprehensive analysis of forest ecosystems. However, ICESat-2 Advanced Topographic Laser Altimeter System photon data contain substantial noise photons and inherently lack terrain-adaptive properties, leading to freque...

Satellite Topographic Mapping in Complex Intertidal Wetlands: A Canopy-Height-Constrained Fusion of ICESat-2 Photon-Derived Structural Samples and Single-Phase Submeter Optical Imagery

High-resolution topographic mapping of intertidal wetlands is essential for geomorphic analysis, yet existing remote sensing methods often struggle with vegetation interference, dependence on dense time-series data, and limited representation of fine geomorphic features. We propose a canopy-height-constrained stratifie...
