摘要
在分析导航型GPS数据的基础上,针对其坐标在电子地形图中实时定位显示的方法及不同坐标系之间转换的问题,提出了一种外业采用导航型GPS接收机配合便携电脑进行野外查图的新方法。实践证明,该方法大大缩短了野外识图与判读时间,降低了查图成本,提高了工作效率。
Based on the analysis of navigation type GPS data, according to the method of coordinates in real time positioning of electronic map display and convert between dif erent coordinate system problems, this paper put forward a kind of new method in field work check map using navigation type GPS receiver with portable computer. Practice shows that this method can reduce the field knowledge chart, reading time and the cost check figure greatly, and improve work efficiency.
