摘要：The development of computer technology and network technology makes network-oriented three-dimensional (3D) visualization an important development direction in the computer field. And the arrival of the era of big data makes it irreplaceable in dynamic simulation, disaster simulation, and supporting decision-making of geographic information systems (GIS). However, the composition in GIS is not static, but dynamically changing, even moving at high speed, such as various transportation vehicles, which brings great challenges to real-time and accurate visualization. How to realize real-time visualization of dynamically changing GIS is of urgent significance. In this paper, the characteristics of real-time positioning of satellite network are considered to design a visualization and analysis method based on satellite network for 3D geographic information (SN-3DGVA). It can sense the change of objects and locate the corresponding change tracks and position, so as to perform 3D geographic visualization analysis.
