      mccombe.mapping.Spherical

public class Spherical
extends CoordinateSystem

Spherical Coordinates - an implementation of positional coordinates based on Latitude and Longitude. Whilst often not explicitly stated in practice, these are relative to a specified datum and ellipsoid.

Constructor Detail

Spherical

protected Spherical()

Creates a new instance of Spherical

Spherical

public Spherical(LatLong latLon,
                 Ellipsoid e,
                 Datum d)

Create a new Spherical Coordinate set based on Lat/Lon, the Ellipsoid and Datum

Parameters:

latLon - A LatLong object containing the Latitude and Longitude of the point

e - The Ellipsoid used to define Lat & Lon

d - The Datum used to determine the Lat / Lon

Spherical

public Spherical(Position p,
                 Ellipsoid e,
