Paper Abstract

It is essential to generate efficient three-dimensional (3D) spatial data model in 3D modeling and visualization, because the data processed is multiple in scale and large in volume. A new vector spatial data structure model based on layered index is proposed according to the geologic data features. It can be used to establish 3D solid model efficiently. Moreover, a dynamic discrete network model is proposed to establish the topological relations for control points in adjoining data layers automatically. The use of topological relations facilitates the implementation of generating surface model. By loading inner attribute data, the 3D solid model is finally established. To evaluate the performance of the approach proposed, a 3D GIS simulation system is developed. The experimental results demonstrate that the approach can generate complex 3D solid model with higher accuracy and better time performance.
