数字城管系统中GIS功能模块的设计与实现

Design and Implementation of GIS Module in Digital City Management System

在城市管理中我们无时无刻都会涉及的各种城市元素,这些都是空间地理信息要素的范畴。GIS具有强大的数据管理、数据挖掘和分析及可视化的能力,能够处理、分析、管理地理空间信息相关数据等。如果数字城管系统与GIS结合,无论是效率上还是性能上都能得到很大的提升。该文以长沙市数字城管系统建设项目为研究背景,对数字城管进行研究和分析,利用Web GIS技术、空间数据库技术、地图服务调用技术三个关键技术,对该模块进行了设计与实现。

In the city management we all the time will involve a variety of elements of the city, these are the areas of geographic information elements. GIS has powerful data management, data mining and analysis and visualization capabilities to process, analyze, manage relevant geospatial information data and other relevant data. If the digital city management system combined with GIS, whether it is able to greatly enhance the efficiency or performance. This thesis is based on the background of construction project of Changsha digital city management system,and have studied and analyzed the digital city management,and using Web GIS technology, spatial database technology, map service invocation technology carried out the design and implementation of the module.
