To determine the horizontal and vertical (3D) coordinates of an inaccessible point using angle and distance measurements to two accessible points defining the direction for offsets and additional distance offsets measurements, for example performed with the tape.
To enter this offset mode, click in the top left corner of the Topo Survey (Optical) dialog, click Measure to expand the sub-menu and select Line and Offset.
Line and Offset mode requires measurement of two locations: HA+VA+SD measurements to two accessible points defining the line direction for offsets. The second measured point of this line is the origin point for calculating offsets.
Note: The vertical coordinate of the inaccessible point is calculated as the vertical coordinate of the second measured point (Point 2) plus entered vertical offset value.
After taking the measurements to two accessible points and entering offset directions and distances, MAGNET Field calculates horizontal and vertical coordinates and stores the inaccessible point to the job. The stored point has the icon in point listings of the current job.
