CORS系统在数字城市地理空间框架建设中的应用

Application of CORS system in the construction of Digital City Geospatial Framework

本文介绍了国家测绘地理信息局对数字城市地理空间框架建设的内容和要求,同时阐述了CORS系统的原理,然后从地理空间框架基准建设、地理信息数据采集、似大地水准面精化三个方面,对CORS系统在数字城市地理空间框架建设中的应用进行了一定的总结。

This paper introduces the State Bureau of Surveying and mapping geographic information of geo spatial framework of the construction of digital cities content and requirement, at the same time, the paper describes the principle of CORS system, then from geo spatial framework of the benchmark construction, geographic information data collection, like the geoid three aspects, the application of CORS in geo spatial framework of the construction of digital cities were summarized.
