摘要
利用南方动态GPS-RTK仪器设备,在马家河沿岸100 m宽、9.7 km长的地带进行了地形测量及断面测量的工作.对不同时段采集的RTK数据进行了比较和分析,并且与传统的全站仪草图法进行了比较.结果是:利用RTK技术在测图半径5 km的范围内完全可以达到测图精度要求而且误差分布均匀,相对传统测图而言,减少了控制点的数量,大大减少了外业测量的劳动强度,减少了外业作业人员的数量,提高了作业效率.
A zoster section survey was conducted of a 100 m×9.7 km terrain on the coast of Majia River with the instrument of South Dynamic GPS-RTK and a comparative measurement was also made of RTK＇s data at different times.By contrasting the data with that collected by using traditional Electronic Total Station draft method,the author comes to a conclusion that RTK technology may well meet the requirements of mapping accuracy and precision for surveying a terrain distributed evenly in the radius of 5 kilometers＇ range.Therefore,it reduces the amount of traditional mapping and the labor intensity of field survey,and improves the working efficiency.
