Angle

Revision as of 15:27, 30 May 2011

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
