| 摘 要： | 在分析应用型地理信息系统传统开发模式的基础上,提出了地理信息系统外壳(GISS:Geographical Information System Shell)的开发模式。然后详细介绍了以GISS思想为指导的地理信息查询外壳(GIQS:Geographical Information Query Shell)的实现,包括系统结构、文件类型、分类编码方案和双向多功能查询的实现。GIQS的索引机制和压缩树形折半查找方法大大提高了操作效率。

| Abstract: | Based on analysis of traditional development models of project-oriented GIS,this pa-
per proposes another model:shell model.Following the thought of“shell model”,a geo-
graphical information query shell(GIQS) is developed.GIQS’implementation is intro-
duced in detail,which includes system structure,main file types of GIQS,classification and
encoding as well as the implementation of“two-direction multi-function query”.The in-
dexing mechanism and“compressed tree-like binary search”greatly improve the efficiency
of GIQS’functions. |
