摘要
GIS(地理信息系统 )的发展继专业化和行业化阶段之后 ,正处于社会化发展阶段。在该阶段 ,GIS的主要作用是为公众提供信息服务。文章在分析了GIS的这种发展趋势的基础上提出了“公众GIS”的概念 ,即 :直接面向公众 ,为公众提供信息服务和辅助公众进行行为决策的地理信息系统。与传统GIS相比 ,公众GIS更具有信息服务业的特点。公众GIS的建设应该突出信息的全面性、现势性和准确性、系统的友好性以及数据的易维护性等原则。公众GIS的关键技术包括数据采集、网络、数据库、多媒体以及系统的友好性设计等技术。公众GIS在建设全国城市公众信息服务网、全国交通旅游信息网以及汽车导航信息系统等方面具有广阔的应用前景。文章对公众GIS的实例———“今日武汉”公众查询系统作了简要介绍。
Following the specialization and profession stages,GIS is developed towards the stage of socialization. At this stage,GIS is expected to provide information service for the public. Based on the analysis of the development of GIS, the authors put forward a new concept,i.e.,GIS for the Public which means “GIS ought to serve the public with information and to assist them to make decisions” GIS for the Public is characterized by its information service as compared with traditional GIS.The general characteristics,technologies and applications of GIS for the Public are stated concisely.Finally, a brief introduction of “Wuhan Now” public inquiring system developed by the authors and the development of GIS for the Pubic in future are given.
