Since the "14th Five-Year Plan", Feiyan Remote Sensing has undertaken more than 10,000 square kilometers of terrain level, city level, component level 3D construction in Jiangsu, Anhui, Zhejiang, Hubei, Fujian, Guizhou, Hebei, Guangdong and Hong Kong, China.
In the pilot project of new basic mapping in Wuhan, it undertook the 3D construction of tilted photography and terrain level, city level and component level real scene of more than 0.03 meters in the central urban area of more than 800 square kilometers. Based on the pilot results, Wuhan integrated to form a unified three-dimensional space-time base of real scenery, and improved the level of urban management; Using terrain level and city level 3D real scene, dynamic simulation of urban inundation situation, formulation of flood prevention emergency plan, flood prevention and control information has achieved remarkable results.
