Based on the review of current 3D spatial modeling and 3D spatial topology methodologies related to 3DGIS and 3DGM, a new 3D geo spatial modeling methodology, named as Analogic Tri Prism(ATP), is presented. ATP represents for 3D geology bodies and structures with 6 elements and 8 groups of topological relationships. The ATPs 3D data structure and topological table are designed; the 3D geo spatial query and analysis method based on ATP are also introduced. A experimental software of ATP is programmed and a 3D geologic model by the software is also introduced.
