Design and Implementation of Three-dimensional Visualization of the Moon Based on Chang’E-1 Data of CCD Camera and Laser Altimeter

The high-resolution and high-definition terrain and image data of lunar surface were successfully collected by Chang'E-1,which provides a real and rich data source for establishing three-dimensional visualization of the whole Moon.By analyzing key techniques of large-scale three-dimensional visualization of spatial data,this paper introduces the design and implementation of functions,structure and work flow of the moon's three-dimensional visualization system,and describes the system's key techniques in detail.The moon's three-dimensional visualization system has some unique solutions for the visual modeling of spatial data,organization mode of raster data and vector data,three-dimensional presentation of the polar region data,dynamic scheduling of data and real-time three-dimensional scene rendering techniques.It realizes the seamless organization,efficient access and seamless browsing of the large-scale data of the whole moon.
