GIS项目程序的设计与实现

二十一世纪是信息化、网络化、数字化、智能化蓬勃发展的新世纪。世界范围的新技术革命和知识经济的浪潮，推动发展中国家和发达国家在电子信息技术的创新和应用领域重新站在同一起跑线上，共同面对新的发展机遇和挑战。在当今这个信息化的社会中，谁能更有效地利用自身资源，掌握更全面、更准确的信息，更快地作出科学的决策，谁就能顺应社会的潮流，在激烈的竞争中站稳脚跟，并同时给企业带来更高的回报。地理信息系统（geographic information system，gis）是一种为了获取、存储、检索、分析和显示空间定位数据而建立的计算机化的数据库管理系统。地理信息系统的处理对象是空间实体，其处理过程正是依据空间实体的空间位置与空间关系进行的。
地理信息系统具有很高的融合能力，它与其它信息技术融合，拓展了整体信息技术的应用。信息化、网络化、数字化、智能化的浪潮汹涌澎湃，数字城市正是这股浪潮的潮头，如果我国能够抓住历史赐予的跨越式发展机会，中国的城市规划、建设和管理水平将极有可能冲进世界先进国家的前列，并带动相关产业的发展。
