2026-01-30 LA Port Functional Area Excavation Results doi:10.57760/sciencedb.36582 en This dataset provides a structured representation of port functional areas extracted from large-scale AIS vessel trajectory data using the PortMiner framework. The dataset is designed to support research on port activity analysis, functional zone recognition, maritime traffic modeling, and intelligent port management. All functional areas are encoded using geohash-based spatial grids, enabling efficient spatial indexing and multi-resolution analysis. Detailed information is provided in the README.md file.
