Line Measurement (Line) - Topcon GTS-600 Series Instruction Manual

4.7 Line Measurement (LINE)

The Line Measurement program allows the user to measure the height of an inaccessible object above
a point. Both the inaccessible object and the point are located along an established base line. Two
prisms, A and B, are set up apart from each other below the object to established the base line. The
horizontal distance is measured and set in the instrument for both prism A and B. The screen then
shows the vertical distance from prism A and B, the horizontal distance from the instrument to prism B,
and the distance along the base line and the screen will display the vertical distance from prism A to
that point, the horizontal distance from that point. Additionally, the vertical distance between two points
on the base line, Points G and L in the diagram, can be measured.
