Tongjiang Aerial

The Tongjiang Aerial Dataset contains georeferenced UAV imagery, positioning sidecars, reconstructed RGB point clouds, and DJI Terra quality reports for an active limestone quarry in Tongjiang County, Bazhong City, Sichuan Province, China. The imagery was acquired on 30 March 2025 with the wide camera of a DJI Matrice 4E and processed in DJI Terra v3.7.0. Version 2.0 expands the point-cloud-only v1.0 release by adding the previously unfinished panorama 2 reconstruction, all five raw image blocks and their RTK/PPK sidecars, quality reports, and integrity manifests. The release contains four panorama surveys (74, 170, 109, and 60 images) and one high-resolution detail survey (884 images), together with eight reconstructed PLY files. The 21 May 2025 timestamps in the original PDF reports are processing/report-generation dates, not acquisition dates. See the included README and file manifest for survey-level quality metrics and provenance.
