java.lang.Object
mccombe.mapping.Position

public class Position extends Object
A Position represents the absolute location of a point in 3D space, independent of any particular Datum, Ellipsoid or type of coordinates. The nature of the internal representation of this point is deliberately encapsulated and irrelevant. This class does not override the toString() method because a Position needs to be part of a CoordinateSystem to have a meaningful String representation.

Instances of this class are immutable.

  • ???????

    • Position

      public Position(XYZ point, Datum datum)
      Creates a new instance of Position based on cartesian coordinates relative to the specified Datum.
      ??:
      point - XYZ coordinates of this position relative to the specified Datum
      datum - The Datum used as the basis of the cartesian coordinates
    • Position

      public Position(LatLong geo, double ellipsoidHeight, Ellipsoid sphere, Datum datum)
      Create a new Position using Lat/Long relative to a specified Ellipsoid and Datum
      ??:
      geo - LatLong of the point
      ellipsoidHeight - Height above the Ellipsoid of this point (double)
      sphere - The Ellipsoid against which this Lat and Lon are defined
      datum - The Datum used to measure the Lat and Lon
  • ??????

    • coords

      public XYZ coords(Datum datum)
      Get the cartesian coordinates of this Position relative to a specified Datum
      ??:
      datum - The Datum against which to measure the Position
      ??:
      Cartesian (XYZ) coordinates of this Position
    • toLatLong

      public LatLong toLatLong(Ellipsoid sphere, Datum datum)
      Get the LatLong of this Position relative to specified Ellipsoid and Datum
      ??:
      sphere - The Ellipsoid to use as reference
      datum - The Datum to measure relative to
      ??:
      A LatLong object for this Position
    • ellipsoidHeight

      public double ellipsoidHeight(Ellipsoid sphere, Datum datum)
      Calculate the height of this Position above the specified Ellipsoid.
      ??:
      sphere - The Ellipsoid from which to calculate the height
      datum - The Datum defining the location of the Ellipsoid
      ??:
      The height in metres of this position above the Ellipsoid
    • equals

      public boolean equals(Object o)
      Compare this Position with another Object
      ??:
      equals ??? Object
      ??:
      o - The Object to compare with
      ??:
      TRUE if o is an instance of Position co-located with this Position.
