MAGNET Field: GNSS offsets

Offset Line

  1. Press the Start Line Press Measure icon.
  2. Press the End Line Press Measure icon.
  3. Distance from end point—toggle button to change direction.
  4. Distance off of line—toggle button to change direction.
  5. Distance up or down—toggle button to change direction.
  6. Point number of the offset point.
  7. Code of the offset point.

Click the Save icon to record the calculated coordinates of the offset point.

Note: Rod height is the last-used height.

Azimuth-Distance-Height

This assumes that you have measured the selected point that will be used to define the azimuth (#4 below).

  1. Start Point along #4 will define the azimuth to the offset point.
  2. Point number for offset point.
  3. Code for offset point.
  4. Point that, along with the Start Point, creates the line of azimuth to the offset point. Must be selected via the Map or List icons.
  5. Vertical offset—toggle to see different options.
  6. Horizontal Distance along the azimuth line. Measure from #4.
    • + is away from start point.
    • – is toward start point.
  7. Click the Save icon to record the coordinates of the offset point.

2 Distance Offset

  1. Measure Point 1.
  2. Offset Distance from Point 1.
  3. Measure Point 2.
  4. Offset Distance from Point 2.
  5. Offset Point Number.
  6. Direction from the line between Points 1 and 2. Choices are
    • Left of line 1-2
    • Right of line 1-2
  7. Input the code for the Offset Point.
  8. Click the save icon to record the coordinates.
