1、XXXX大学毕业论文二○○八年六月55基于Shape的电子地图显示系统专业班级：姓名：指导教师：信息科学技术学院55内容摘要地理信息系统，即GIS（GeographicInformationSystem）是在计算机软件和硬件的支持下，管理和综合分析具有地理空间内涵的各类资料，以提供对规范化、管理、研究、预测和决策所需信息的技术系统。它是表达、模拟具有地理空间内涵的现实系统和进行数据通信处理、分析的有力工具。Shape文件是一种基于文件方式存储GIS数据的文件格式。至少由.shp,.dbf,.shx三个文件组成，分别存储空间信息、属性信息和

2、前两者的关系。是GIS中比较通用的一种数据格式。电子地图是可任意放大缩小的矢量地图，它是通过GIS和数字制图技术来实现的，依托于互联网等数字媒介的地图。本课题以GIS理论为基础，用VisualC++6.0作为开发工具，通过分析shape文件格式，完成对shape文件数据读取，将地图显示出来并实现放大、缩小、漫游功能。关键词：地理信息系统，电子地图，Shape55ABSTRACTGeographicInformationSystemisthetechnologysystem,whichisusedtomanageandanalyzegeog
