public abstract class AbstractProjection
- extends java.lang.Object
- implements Projection
Implementation of the Projection interface that represents a coordinate reference system and delegates
the real projection and datum conversion to other classes.
It handles false easting and northing, central meridian and general scale factor before calling the
delegate projection.
Forwards lat/lon values to the real projection in units of radians.
The fields are named after Proj.4 parameters.
Subclasses of AbstractProjection must set ellps and proj to a non-null value.
In addition, either datum or nadgrid has to be initialized to some value.
