In mensuration, three angles are important:
- Inclination 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.
