后处理差分GPS在南极格罗夫山中小比例尺地形图测图中的应用

THE APPLICATION OF POST-PROCESSING DIFFERENTIAL GPS IN PLOTTING AT ANTARCTIC GROVE MOUNTAINS

针对极地地区恶劣的工作环境 ,本文提出了一种全新的极地测图方法差分GPS测图。通过中国第 1 6次南极科学考察格罗夫山考察的实践表明 ,后处理差分GPS配合以全站仪进行测图 ,速度快 ,省时省力 ,完全可以满足 1∶1万或更小比例尺成图的要求。不失为极地地区大批量地形数据采集的一种有效手段。

Considering the abominable condition in polar region, a new method of surveyingDifferential GPS was put forward in this paper. The practice of author in Antarctic Grove Mountains during CHINARE 16 (Chinese National Antarctic Research Expedition 16) shows that the method of post processing GPS assisted with Total Station is generally applicable and efficient. It is completely satisfied with the acquirement of a topographical map in 1∶10000 or smaller scale. And the method of GPS is a convenient means to collect considerable topographical data in polar region.
