The project revolved around enhancing the management of navigation infrastructure along the Yangtze River. This endeavour was realized through a partnership between the local Hydrographic Survey Bureau in China and CHCNAV's technical experts. The deployment of the AlphaAir 10 LiDAR system for aerial survey operations, primarily around the Hanjiang Bridge section, aimed to achieve meticulous data collection and processing. This initiative marked a significant stride forward in the realm of waterway surveying along the Yangtze River, promising improved efficiency and safety standards.
