信息高速公路与地理信息系统──综述地理科学的信息革命

国家信息基础设施(NII)是一个能为全球广大用户提供大量信息及信息服务的计算机网络系统,其雏形Internet已连接了全球150多个国家和地区,并提供了诸如新闻广告、电子邮件、远程对话等一系列服务.中国也已经以“金桥工程”为起步开始实施中国国家信息基础设施计划.国家空间数据基础设施作为其组成部分之一,其核心是WebGIS的建设以及地理空间数据的标准与规范化.同时信息高速公路建设为GIS的发展也创造了新的条件,促进了WebGIS等的发展,改变了GIS集成方式,拓宽了GIS应用领域,并将推动地理科学的信息革命.

INFORMATION SUPER HIGHWAY AND GEOGRAPHICAL INFROMATION SYSTEM

National Information Infrastructure (NII), also called Information Super Highway (ISH) is a computerized network system which provides world wide users with huge amount of information and other information services. Its prototype Internet, has linked more than 150 countries and regions together, and provides a series of services such as News, Email, electronic library. China NII has been constructing with the start of Golden Bridge project. National Spatial Data Infrastructure (NSDI) has been listed as the important component of NII, the key to the success of NSDI is to develop WebGIS and draft of the standard and normal for geo spatial data and their exchange. The development of ISH will give a new opportunity for GIS. It will promote the development of WebGIS, change the mode of integration of GIS, remote sensing and other related technologies, widen the GIS application field, and therefore promote the information revolution of geographical science.
