此实践用于使用Face Technologies Stick®手动收集精度轮廓数据。油尺测量剖面（相对高差）的速度和精度高于传统的杆式和水准仪测量。描述了测量纵向和横向轮廓的程序。有经验的操作员使用此程序可以每小时获得500个读数。

This practice is used to manually collect precision profile data utilizing the Face Technologies Dipstick®. The dipstick measures profiles (relative elevation differences) at a rate and accuracy greater than traditional rod and level surveys. Procedures for measuring both longitudinal and transverse profiles are described.Experienced operators have been able to obtain 500 readings per hour using this procedure.
