REM Measurement

An REM measurement is a function used to measure the height to a point where
a target cannot be directly installed such as power lines, overhead cables and
bridges, etc.
The height of the target is calculated using the following formula.
Ht = h1 + h2
h2 = S sin θ z1 x cot θ z2 - S cos θ z1
