GIS二维、三维空间信息查询功能的实现与应用

The Implementation and Application of 2DGIS and 3DGIS Spatial-attribute Mutual Query

空间信息查询是GIS中的重要功能之一 ,因而也是GIS软件开发人员的工作重点之一。从中国大陆岩石圈GIS这一实际应用出发 ,在分析相关技术的基础上 ,提出了一套GIS二维和三维空间—属性数据交互查询的实现方法 ,并将此方法用于GIS软件平台开发 ,实现了高效的功能。最后给出应用实例 ,结果证明了这种方法的可行性和实用性。

Spateial information queries are the key functions in the GIS.The realizations of practical and effective GIS queries are also the work emphases of the GIS software developers.During the process of the China Continental Lithosphere GIS realization,we put forward one set of technique to realize the two and three-dimensional spatial and attribute mutual queries,and then applied it to GIS platform developing rocess.We give applied examples,and the results prove the feasibility and effectiveness of this technique.
