摘要
分析了在公路勘测放线中由于存在长度投影变形 ,使中线交点产生位移和引起中线偏离的误差影响 。
The length projection distortion in route_placing process in road survey is analyzed.The distortion could cause displacement to mid_line joint point and deflection to mid_line.On the basis of this, the measures are presented to reduce the impacts of length distortion error on the route_placing precision.
