GeoVisibleRegion

GeoVisibleRegion[{lat,lon,h}]

is a two-dimensional GeoGraphics primitive that represents the region on the surface of the Earth visible from the point of coordinates lat,lon and height h above the reference ellipsoid.

GeoVisibleRegion[pos]

represents the region visible from the position pos.

Details

  • GeoVisibleRegion assumes an ellipsoidal shape for the Earth and does not take into account the terrain elevation. Corrections for atmospheric refraction are not included.
  • The angles lat,lon in GeoVisibleRegion[{lat,lon,h}] can be given as numeric objects in degrees, DMS strings, or Quantity angles.
  • The height h in GeoVisibleRegion[{lat,lon,h}] can be given as a numeric amount of meters or as a Quantity length.
