To determine the horizontal and vertical (3D) coordinates of an inaccessible point as the intersection of two lines, which are defined by measuring two accessible points on each of the two lines.
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 Two Lines Intersection.
Two Lines Intersection offset mode requires four measurements to define two lines which intersection is an inaccessible point. Measure HA+VA+SD to two accessible points on each line.
Note: The height of the inaccessible point is calculated as the mean of heights of each line at the intersection point.
After taking four measurements, 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.
