Setup by Grid Lines

To determine the position of an occupation point using measurements to two points on each of two known lines and calculated distances from the intersection point of these known lines to each measured point.

To use this type of resection, MAGNET Field requires data on two known lines intersecting each other and two measured points on each of these lines. Based on this data, MAGNET Field calculates four distances from the known lines intersection point to each of the measured points and performs resection to these points.

To configure resection settings, click and select Options from the dialog menu. Configured settings retain between sessions.

The resection wizard helps you to perform the procedure:

  1. Specify the occupation point in the Define Instrument setup group.

  2. Specify known lines intersecting each other: Line 1 and Line 2 in their respective groups.

  3. Measure any two points on each of two specified lines along line's direction:
  4. At this step, specify and measure four points successively: first point on first grid line, second point on first grid line, first point on second grid line, second point on second grid line.

    Note: Maintain the correct direction of the grid lines. The first point should be closer to the start of the line than the second one.
