Constructor Detail

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,
             java.lang.String name)

Parameters:

equatorRadius - _more_

poleRadius - _more_

reciprocalFlattening - _more_

name - _more_
