Calculate the distance to horizon depending on elevation plus height of observer, or distance to visible object behind the horizon.


Distance from Observer to Horizon

Distance = √((R+h)²-R²)

  • R (Radius of Earth)
  • h (Elevation + Height of Observer)

Distance from Observer to Object behind Horizon

Distance = √((R+h)²-R²) + √((R+H)²-R²)

  • R (Radius of Earth)
  • h (Elevation + Heigth of Observer)
  • H (Elevation + Heigth of Object)

DIP correction in minutes of arc

DIP correction = 1.760 * h

  • h (Elevation + Heigth of Observer) in Meters
