The three-dimensional data organization method based on GeoSOT-3D

With the development of earth observation technology, three-dimensional geo-spatial information acquisition and update capabilities have achieved rapid development. How to effectively organize and manage massive spatial data and related information has become an urgent problem to be solved. In this paper, according to the idea of global subdivision, we propose a design and implementation of the global spatial data organization. The method firstly process spatial data in multi-scale subdivision based on GeoSOT-3D, and then three-dimensional volume data and field data is organized. Compared with the existing local three-dimensional grid or global three-dimensional grid for certain purpose, our method is more suitable for worldwide large scale data organization and provide a new idea for the effective organization of the global spatial data.
