On the basic of analyzing the spatial distribution of the hydrogeologic stratum , it abstracts the concept module of the void hydrogeologic profile , and sets down the rule on making up the stratum section , it also analyses the data structure and the steps of automatic generating the hydrogeologic profile , and discusses the appliancation of component gis on the the automatic generate method 在分析孔隙水文地质层的空间分布规律的基础上，抽象出孔隙水文地质剖面的概念模型，制定了地层剖面构建规则。同时，本文也分析了自动构建水文地质剖面图的数据结构及其构建剖面的具体流程，并探讨了组件式gis技术在自动绘制水文地质剖面图中的应用。
During the process of traffic planning , with the help of gis on the computer , we can found , compile , manifest and manage the urban transportation information , and analysis the linear geographical net in a space way , and provide the information to the user in a direct , clear - cut , and all - inclusive way 在城市交通规划过程中，可通过地理信息系统借助计算机建立、编辑、显示、查询和管理城市交通信息，并可对城市交通网络进行空间分析，将城市交通规划中具有空间特征的信息进行可视化表达。
The gls of forest resource intbrmation was used in decision - making and can displaying , cartography , dtlai - comprehensive querying and conditional querying of spatial and attributed data , spatiai anaiysis , model analysis , dynamic monitoring and data update . the webgls of forest resource information was used to release forest resource information and share the function of gis . users on the internet can realize some function of gis on the forest resource in forest farm through tileir browsers , sucn as graphica1 operation , comprehensive querying and conditional querying , buffer analysis , map measure , etc . users can also express their proposals and edit the graphical and attributed data and return these results to webserver so to realize mutual exchange 森林资源gis用于林场辅助决策，它可以进行显示与制图、空间属性数据双向综合查询与条件查询、空间分析与模型分析以及动态监测和数据更新；森林资源webgis用于森林资源信息发布及gis功能的共享， internet用户通过浏览器即可对林场森林资源实现gis的许多功能，如图形操作、综合查询与条件查询、缓冲区分析、图形测量等，用户还可以发表建议或对图形及属性数据加以修改并将这些结果返回服务器端，以进行相互交流。
