摘要
根据城镇地区建筑物的特点。本文提出了两种既减少外业实测点数,又能满足计算机绘图要求和精度的野外采样方法,并以SET2全站式电子速测仪为例,分析了这种电子速测仪按极坐标法采样的精度,又据SET2电子速测仪实测的数据,统计了本文提出的两种采样方法的精度。
According to the characteristic of Building in urban area, this paper presents two sampling methods, which can decrease the measured points and satisfy the accuracy and requirement of the computer-aid drawing, and analyses the sampling accuracy of the SET2 electronic tacheometer with polar coordinata method. Finally the accuraty of the two methods are counted up according to the measurement of SET 2 electronic tacheometer.
