  • Constructor Details

    • Earth

      public Earth()
      Spherical earth with canonical radius.

    • Earth

      public Earth(double radius)
      Create a spherical earth.
      Parameters:
      radius - radius of spherical earth.

    • Earth

      public Earth(double equatorRadius, double poleRadius, double reciprocalFlattening)
      Create an ellipsoidal earth. The reciprocalFlattening is used if not zero, else the poleRadius is used.
      Parameters:
      equatorRadius - equatorial radius (semimajor axis) in meters, must be specified
      poleRadius - polar radius (semiminor axis) in meters
      reciprocalFlattening - inverse flattening = 1/flattening = a / (a-b)

    • Earth

      public Earth(double equatorRadius, double poleRadius, double reciprocalFlattening, String name)
      Create an ellipsoidal earth with a name.
      Parameters:
      equatorRadius - equatorial radius (semimajor axis) in meters, must be specified
      poleRadius - polar radius (semiminor axis) in meters; if reciprocalFlattening != 0 then this is ignored
      reciprocalFlattening - inverse flattening = 1/flattening = a / (a-b); if 0 use the poleRadius to calculate
      name - name of the Earth
