In mensuration, three angles are important:
- 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
Elevation angle (with Zenith-, Nadir- and angle of inclination)
Azimuth/direction angle
Angle of refraction
