The framework model of the earth is the core framework of digital earth system, it directly affect the success of constructing digital earth system, and has a profound effect on the usability and user-friendly of the system. It can promote the speed of construction of digital earth system, and can enhance user's understanding of the digital earth system. This paper firstly discuss how to construct...
This paper expounds the important application of the transform thought to solve building template matching problems based on building skeleton matching in large-scale topography map. A new building template matching algorithm via their substitution is proposed. The algorithm workflow is iterative to match pre-defined templates. Skeleton of building polygon is extracted based on point set Voronoi diagram...
Large-scale 3D city building models has now become an indispensable part of digital globe information system. It is a big challenge how to make use of limited computer memory space and rendering ability to draw almost infinite city building models on the earth. In this paper, we focus discussion on how to improve the efficiency of management and rendering of largescale 3D city building models, which...
