| Title: | QTPV data model and algorithm and its application to geological exploration engineering | Authors: | Cheng, P Shi, W Gong, J Zhou, G |
Issue Date: | 2005 | Source: | Geo-spatial information science (地球空间信息科学学报), Mar. 2005, v. 8, no. 1, p. 64-71 | Abstract: | D spatial data model and simulating are the core of 3D GIS can be adopted in different domains. A data model based on Quasi Tri-Prism Volume (QTPV) has been proposed. QTPV definition and its special cases have been discussed. Using QTPV and its special cases, irregular natural geological bodies and regular subsurface engineering can be described efficiently. The proposed model is composed of five primitives and six objects. Data structures and topological relationship of the fives primitives and... 更多 | Keywords: | GIS QTPV Data model Algorithms Visualization Subsurface engineering |
