| 摘 要： | 本文概述国外测绘机构大地测量的动向 ,目的在于了解全球大地测量的发展趋势 ,作为借鉴。综观各国的大地测量动向可以看出 ,高精度国家大地控制网的建立 ,都是采用 GPS,无一例外 ,而且它们之间只是细节上的差异。从各国建立高精度大地控制网的目的来看 ,都是为多学科服务的。面对这样的总趋势 ,大地测量工作者必须拓宽知识面 ,迎接新的挑战。

| Abstract: | This paper summarizes geodetic activities in foreign organizations of surveying and mapping with the aim of realizing the worldwide tendency in the development of geodesy. A comprehensive review of these activities shows that the establishment of national high accuracy geodetic networks is all made by means of GPS without exception,they exhibit only slight difference in details.Taking a gereral view of the objects of national high accuracy geodetic networks of various countries,it is obvious that they are all of service to multiple scientific disciplines,under the circumstances,as geodesists,we must broaden our realm of knowledge to cope with the new challenge. |
