【摘要】 针对传统野外地质填图中手段落后、填图精度不高以及工作效率低的特点,文章探讨了手持GPS接收机在野外区调地质填图中标定地质点、导航、计算多边形面积以及补点等方面的应用及其注意事项,提出了将GPS手持机绝对定位结果标定在地形图上的一个简单而新颖的方法,大大增强了GPS手持机在野外地质填图中的实用性。更多还原

【Abstract】 Aiming at characteristics of backward methods,lower precision and working efficiency in the traditional field geological mapping,application of hand-holding GPS receiver in geological point demarcation,navigation,polygons area calculation,and point supplement are discussed.A simple but novel method for demarcating absolute results by hand-holding GPS receiver on a topographical map is brought forward.These will extend practicability of handholding GPS receiver in the field geological mapping.更多还原
