??????:
Lambert, Orthomorphic, TransverseMercator

public abstract class Projection extends CoordinateSystem
A Projection is an abstract base class for CoordinateSystems in which a a 3-dimensional position is "projected" onto a surface to allow it to be represented in 2-dimensions.

    • Projection

      protected Projection()
      Creates a new instance of Projection
    • Projection

      public Projection(Position p, Ellipsoid e, Datum d)
      Create a new Projection for a Position. The projection uses a specified Ellipsoid and Datum.
      ??:
      p - The Position
      e - Ellipsoid to use
      d - Datum to be used.

    • toEN

      public abstract ENPair toEN()
      Get a 2-dimensional representation of the projected position as easting and northing distances
      ??:
      An ENPair representing the projected Position
    • gridConvergence

      public abstract double gridConvergence()
      Calculate Grid Convergence - the angle between the North axis and True North at this particular point.
      ??:
      Grid convergence (radians)
