放样主要是把图上设计的坐标与高程在实地标定出来,是测量坐标的一个反过程。常规作业时主要采用全站仪放样,一般至少需要两人合作,且要求测站点与放样点要通视才行,若不通视,还要进行转站。采用RTK进行放样,只要把放样点的坐标输入到手簿中,测量员拿着GNSS接收机,根据提示移动到放样点上,其精度也较高,各放样点的误差影响也是独立的,对GNSS-RTK技术在对点、直线、中线等进行详细放样的步骤和精度进行具体分析。
Stakeout is mainly designed to map the coordinates and elevation calibration in the field, is an inverse process of measuring coordinates. General operation of the main use of total station lofting, the general need at least two people cooperation, and requires the station point and out of the spot to look for job, if not, but also transfer station. RTK lofting, as long as the coordinates of the staked point input to the hand book, surveyors holding GNSS receiver, according to the prompts to move to the staking point, its accuracy is higher, the impact of staking point error is independent, the GNSS -RTK technology in the point, straight line, midline and other detailed steps and the accuracy of the specific analysis.
