“天地图”是国家地理信息公共服务平台,它是“数字中国”的重要组成部分。“天地图”的目的在于促进地理信息资源共享和高效利用,提高测绘地理信息公共服务能力和水平,改进测绘地理信息成果的服务方式,更好地满足国家信息化建设的需要,为社会公众的工作和生活提供方便。 “天地图”运行于互联网、国家电子政务网、移动通信网等网络环境,以门户网站和服务接口两种形式向公众、企业、专业部门、政府部门提供24小时不间断“一站式”地理信息服务。 各类用户可以通过“天地图”的门户网站进行基于地理位置的信息浏览、查询、搜索、量算,以及路线规划等各类应用;也可以利用服务接口调用“天地图”的地理信息服务,并利用编程接口将“天地图”的服务资源嵌入到已有的各类应用系统(网站)中,并以“天地图”的服务为支撑开展各类增值服务与应用,从而有效缓解地理信息资源开发利用中技术难度大、建设成本高、动态更新难等突出问题。 TIANDITU is the website providing “one-stop” geospatial information services to personal users, enterprises, professional agencies and governments via networks such as Internet, communication network, Intranet, etc. It is the National Platform for Common GeoSpatial Information Services, which is created by National Administration of Surveying, Mapping and Geoinformation of China (NASG) as an important part of the geospatial framework for digital China aims at promoting the geographic information resources sharing, and improving the ability and efficiency for services. Website users can browse maps, locate places, measure distances or areas, plan car driving routes, while professional users can access various TIANDITU’s service resources via standardized interfaces for value-added services and applications. TIANDITU also provides many Application Programming Interfaces (APIs) to facilitate the integration of its service resources and various systems or websites. With these standardized interfaces and APIs the users can avoid the chaos for handling, maintenance and updating the base maps and focus on their own thematic data and applications. Thus decrease the development and research cost for providing commercial or professional applications.
