In order to solve bottleneck problems such as slow and difficulty of real-time presentation and browsing of large-scale realistic models,aiming at the landform and ecological characteristics of wetland parks,this paper used examples as the research object to study the efficient three-dimensional modeling and lightweight presentation technology of UAV aerial survey data of wetland parks.Based on the linear combination equation of quadratic Gaussian radial basis function,this paper proposed a quadtree segmentation three-dimensional modeling algorithm for aerial survey spatial position data,and r...
