GeoHemisphere

GeoHemisphere[]

is a two-dimensional GeoGraphics primitive that represents the half of the Earth centered at your current geo location.

GeoHemisphere[loc]

represents the half of the Earth centered at the location loc.

Details

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