GeoHemisphereBoundary[]

is a one-dimensional GeoGraphics primitive that represents the boundary line of a hemisphere of the Earth centered at the current geo location.

Details

  • The boundary of a hemisphere is a line contained on a plane that goes through the center of the Earth. Hence this line is a great ellipse.
  • The location loc can be specified as latitude and longitude coordinates {lat,lon} in degrees, as GeoPosition[{lat, lon}], or as named entities Entity[…].
