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实践 ,介绍了大地测量学当前发展的国际背景 ,提出了我国大地测量学今后的发展方向 ,如建立现代大地坐标框架和现代重力基准的目标和任务 。
The role of geodesy, as the datum of surveying and mapping,for providing the fundamental frame of GIS is briefly discussed.The establishment of national horizontal,vertical and gravity datum in China is reviewed.The international background for the development of today's geodesy is 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.
