All Implemented Interfaces:

Serializable, DiscreteDomain<HorizontalPosition,GridCell2D>, DiscreteHorizontalDomain<GridCell2D>, Domain<HorizontalPosition>, HorizontalDomain, HorizontalGrid

Direct Known Subclasses:

```
public abstract class AbstractTransformedGrid
extends Object
implements HorizontalGrid
```
This is an abstract implementation of a HorizontalGrid for which there exists a transformation to convert WGS84 to the native CRS. This transformation is invisible externally - i.e. getCoordinateReferenceSystem() will return DefaultGeographicCRS#WGS84 and all operations behave as though this is the co-ordinate reference system. However, this class also exposes the method transformNativeHeadingToWgs84(double, double, double, double) so that vector transforms can be handled.

public abstract double transformNativeHeadingToWgs84(double xComp,
                                                     double yComp,
                                                     double lon,
                                                     double lat)
```
    Transforms a heading in native grid co-ordinates (degrees clockwise from positive y-direction) into a heading in WGS84 (degrees clockwise from north).
    
    Parameters:
    
    xComp - The x-component of the heading
    
    yComp - The y-component of the heading
    
    lon - The longitude of the given components
    
    lat - The latitude of the given components
    
    Returns:
    
    The transformed heading
  - getCoordinateReferenceSystem
```
public final org.opengis.referencing.crs.CoordinateReferenceSystem getCoordinateReferenceSystem()
```
    Always returns DefaultGeographicCRS#WGS84. Transformations between native CRS and WGS84 are done behind the scenes
