Application of 3D Visualization of Remote Sensing Images for Airport Construction in Tengchong County, Yunnan Province, China

This paper selected multi-source and multi-scale data to realize the 3D visualization of remote sensing images through digital processing and high-precision DEM modeling.bDigital Elevation Model (DEM) shows terrain factor, and images of surface textures cover the real situation. With ERDAS software support , we modeled the virtual three-dimensional flight by integrating the image data and the DEM perspective surface to overlay a variety of humanities, natural feature information such as spatial data. Take Tengchong airport as example, we extracted spatial information and analyzed the barrier in obstacle clearance to visualize the complex and abstract data. Thus, we can make an accurate assessment on budget of construction at the airport.
