基于组件的服务器端共享地图符号库的研制

共享地图符号库是空间信息网络共享和交互式分析服务中的重要研究方向。本文以福建省3S应用综合服务平台、福建省政务信息共享平台中空间信息共享符号库建设为例,在分析基于GIS的地图符号库设计和实现技术基础上,结合多源空间信息网络共享、表达和分析服务的特点,提出一种面向网络综合服务应用的数字地图符号库的设计原理。基于GIS组件ArcObject开发一个分布于服务器端的共享地图符号库系统原型,并对其中的符号编辑、存储和管理的功能,以及符号化实施,作了详尽的叙述。该系统已集成于福建省政务信息共享平台服务代理系统上,初步实现了面向跨部门、跨行业网络共享和交互式分析的应用要求。

Design and Realization of Web-shared Map-Symbol-Base in Server-end Based on GIS Component

Web-shared digital map-symbol-base is an important research direction associated with sharing spatial information on the internet and interactive analyzing service. In this paper, we illustrate how the shared digital map-symbol-base was integrated into the Fujian province e-government information sharing platform service agent system, and analyze the present technique about designing and developing of shared digital map-symbol-base based on GIS component.A design principle on digital map-symbol-base faced network service application has been presented. By using GIS component ArcObject (ArcObject is built using Microsoft′s Component Object Model (COM) technology), the prototype of shared digital map-symbol-base has been established and its functions of symbol editing, storing and managing as well as its symbolizing process have been explored in detail. By integrating into the Fujian province e-government information sharing platform service agent system, the shared digital map-symbol-base can primarily meet the application demand on sharing spatial information based on the Internet and interactive analysis service in different departments and different realms of profession.
