摘要
结合国家“九五”重点课题及在包头市郊区的实验，介绍了全球定位系统的定位原理和特点，阐述了包头市郊区土地资源动态监测工作中的ＧＰＳ选型思路、基准站建立方法、外业数据采集方法、外业测量记录内容和ＧＰＳ数据的内业处理过程等关键环节。
It is very meaningful to master land resources status exactly and quantitatively. Traditional method of land resources changing can not locate land units accurately, with high error. Combining the key project of “the ninth Five_year Plan”. This paper introduces positioning principle and characteristics of Global Positioning System (GPS), describes the type selecting clues applied to dynamic monitoring land resources of a suburb of Baotou as well as base station establishing methods, data acquiring methods and surveying record of outdoor work, key steps of GPS data processing and so on.
