To determine the horizontal and vertical (3D) coordinates of an inaccessible point using coordinates of two measured 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 (GNSS) dialog, click Measure to expand the sub-menu and select Offset Line.
Offset Line mode requires coordinates of two points defining the line direction for offsets. The end point of this line is the origin point for calculating offsets.
Note: You can define the direction of any offset in two ways: either click on the corresponding button of the current selection, or use the minus sign "-" for the current value. For instance, Forward 12.000 and Backward -12.000 directions are the same.
Note: The vertical coordinate of the inaccessible point is calculated as the vertical coordinate of the end point of the line plus entered vertical offset value.
After specifying the reference line and offset data, click to calculate horizontal and vertical coordinates and store the inaccessible point to the job. The stored point has the
icon in point listings of the current job.
