2026-08-11 A Quality-Controlled GPS Trajectory Dataset for Seven Tourism Study Areas in Sichuan doi:10.57760/sciencedb.45862 en This dataset contains 5,385 quality-controlled GPS trajectories from seven tourism study areas in Sichuan, China. The trajectories were derived from 39,007 raw trajectory blocks through coordinate and timestamp validation, boundary clipping, trajectory segmentation, duplicate removal, and quality filtering. The dataset is provided as seven UTF-8 CSV files and includes trajectory identifiers, longitude, latitude, elevation, timestamps, elapsed time, speed measurements, and quality-control flags. Coordinates use WGS 84 (EPSG:4326). The data can support tourist-mobility analysis, trajectory preprocessing, spatial clustering, route retrieval, and trajectory-similarity research.
