"3D UrbanPLMap"

"This dataset is designed for multi-altitude 3D path loss (PL) map prediction in urban wireless environments, specifically tailored for Unmanned Aerial Vehicle (UAV) communication modeling. It is constructed using high-fidelity ray tracing (RT) via the Sionna-RT simulator at a carrier frequency of 3.5 GHz. The data is based on the STPLS3D point cloud dataset, encompassing diverse urban features including buildings, vegetation, and terrain variations.The dataset consists of 52,500 samples derived from 25 main scenes. Each sample provides 20 altitude planes ranging from 5 m to 100 m with 5 m intervals, resulting in over 1.05 million PL maps. Each entry includes:- Environmental inputs: High-resolution height maps and semantic class maps (ground, vegetation, buildings).- Transmitter (Tx) data: Tx location maps and explicit geometric features (Euclidean distance and horizontal displacement).- Ground truth: Corresponding path loss maps generated through RT simulations."
