摘要
该文阐述基于可视化技术的地下水含水层结构的立体表达方法。为了实现基于水文地质钻孔数据库的各种专题图形的自动生成,讨论了结合水文地质钻孔数据库的平面格网数据的组织模型,以及在该模型基础上的数据结构设计、算法设计和程序设计方法。给出了地下水含水层可视化具体实例的计算结果。由实例可知,该方法是有效的,且在地下水含水层可视化、地下地质体的立体表达等领域有一定的应用价值。
On the basis of the general introduction of the conception and significance of the spatial data visualization, this paper discusses how to visualize the groundwater aquifer according to the 3D visualization technology. For all kinds of automatic thematic mapping using the database of the groundwater borehole, this paper firstly researches deeply into the organizational model of the GRID format data combined with the borehole database, and then designs the data structure, algorithm, and the program on the basis of the model. At last it also demonstrates an example and the result of the computation, and from which we know the algorithm is efficient and significant on the 3D visualization of groundwater aquifer and geologic body.
