None known No LiDAR was found after a genuine search of national, regional and international sources.
No national or regional airborne LiDAR programme with openly licensed data, and no openly licensed DEM at 5 m or finer, was identified for China in the national mapping agency, open-data portals or OpenTopography during the October 2026 review. Global DEMs such as Copernicus GLO-30 remain the practical elevation source. OpenTopography hosts numerous research surveys of active faults, such as the CC BY 4.0 Haiyuan rupture point cloud.
Free is not the same as open. Cost is what you pay to get the data; the licence says what you may do with it. How cost and licence are defined
