摘要
概述了大地测量学作为测绘基准、提供地理信息系统的基础框架作用。回顾了我国大地测量在建立国家平面基准、国家高程基准、国家重力基准等方面的情况。论述介绍了大地测量学当前发展的国际背景 ,提出了对我国大地测量学今后发展 ,如建立现代大地坐标框架和现代重力基准的目标和任务 ,以及改善国家高程基准等方面的考虑。
The role of Geodesy, as the datum of surveying and mapping, for providing the fundamental frame of Geographical Information System is briefly discussed. The establishment of national horizontal, vertical and gravity datum in China is reviewed. The international background for the development of geodesy at presentis introduced. The goals and tasks of the development of geodesy in next 5~10 years in China are suggested, such as the establishment of Chinese modern geodetic coordinate frame and gravity datum, and the renew of Chinese vertical datum.
