摘要：在数字化测图的外业工作中,常常采用全站仪极坐标法测量图根点。随着测站数和测点距离的增加,图根点平面位置误差也在不断地变大;但人们在理论上对此讨论较少。通过图根点的误差的计算和分析,得出了在点位误差允许值以内,测站数和测点距离的合适范围;并验证了规范规定的每幅图所需的图根点的个数。
In the field digital mapping, the mapping control point is often surveyed using the total station polarcoordinate method. With the increase of the station number and survey point distance, the plane positional error ofthe mapping control point is continually larger. But there are few discussions on it theoretically. The errors of themapping control point are calculated and analyzed, and has obtained the appropriate range of the station numberand survey point distance within the permissible value of error. The number of the mapping control point of eachmap sheet required by specification for digital mapping has been also verified.
