Analysis and construction of R-tree index for 3D geological model based on STR
基于STR算法的三维地质模型R树索引构建与分析*

Considering the layered distribution and the thin irregular geometric characteristics of geological bodies, proposed multi-body spatial index based on the STR algorithm. Discussed in detail the preprocessing of constructing index and treatment for fault-type geological objects and whole-region geological objects. Experiments show that the overall performance of multi-body R-tree index based on STR algorithm is better than the traditional R-tree and the constructing order in X, Y, Z direction affects the query performance for different types of geological structure model.
