In mensuration, three angles are important[1]:
- Elevation angle
Specifying the elevation of a distance - Azimuth or direction angle
Angle that is constructed by a distance and a defined direction (in geodesy mostly a north direction) - Angle of refraction
Angle constructed by two distances
Note that angles are always read in clockwise direction- direction angles based on the north direction, angles of refraction from the preceding to the following reference point.
Elevation angle (with Zenith-, Nadir- and angle of inclination)
Azimuth/direction angle
Angle of refraction
