文中从地理信息系统、遥感技术、全球定位系统、无线通讯技术等方面介绍了信息技术在加拿大的发展和应用情况。地理信息系统是空间信息管理的平台,在政府和许多行业中有广泛的应用,在互联网上掀起了电子地图和位置搜索的应用浪潮;遥感技术是信息采集的重要手段,在数据处理技术方面不断进步,广泛应用于城市和环境研究;全球定位系统是空间定位的重要工具,包括导航GPS和测量GPS两大应用领域;通讯技术是信息传递的基础,无线通讯网的发展,为分布式移动计算创造了条件。随着各种信息技术的发展和普及应用,一种以空间信息服务为特征和载体的产业G-business正在形成。

It presents the development and application of information technology in Canada from GIS, RS, GPS and wireless communication technology. GIS is the management platform of spatial information, widely used in government and industries, and drives the application tide of eMap and location searching on Internet. RS is the important means for information collection, widely used in urban and environment studies with its constant improvement in data transaction technology. GPS is the important tool for spatial positioning, including navigation GPS and surveying GPS. Communication technology is the basis of information transmission, and provides the necessary condition for distributed moving computing by wireless communication network. With the development and application of all the information technology, one industry named G-business is forming with the characteristic and carrier of spatial information service.
