Computing an Azimuth

Using the Sun

The azimuth for a hidden point measurement can be computed using a known point and the
sun. The known point can be manually occupied. The location of the hidden point can be
away from the sun or in the direction towards the sun. Ensure the shadow of the pole falls in
the direction of the point.
