摘要
In the application of large scale aboveground and underground entity 3D modeling and spatial analysis, it is a key issue as how to realize integrated organization and management of massive 3D spatial data efficiently due to the diversity and unbalanced distribution of 3D models. A 3D spatial database model considering spatial and semantic relationships is proposed to solve this problem and corresponding concept model, logical model and physical model are also presented. Especially aiming at the complexity of geological bodies, the multi-scale underground spatial object concept model considering semantic and multi-level 3D spatial index mechanism is put forward.
