```
    Parameters:
    
    domainSet - The CoordinateSystem, eg. (line, element), (Track, XTrack)
    
    lonlatSet - The set of earth locations to interpolate for (x,y) to/from (lon,lat). May be sampled w/respect to domainSet, eg. every fifth point. SetType must be SpatialEarth2DTuple or LatitudeLongitudeTuple.
    
    neg180pos180 - The range of longitude values in the lonlatSet. Default is true, false is (0,+360).
    
    Throws:
    
    VisADException - Couldn't create necessary VisAD object or reference type (the lonlatSet type) is not SpatialEarth2DTuple or LatitudeLongitudeTuple

    Description copied from class: CoordinateSystem
    
    Convert RealTuple values to Reference coordinates; for efficiency, input and output values are passed as float[][] arrays rather than RealTuple[] arrays; the array organization is float[tuple_dimension][number_of_tuples]; can modify and return argument array. This implementation converts the input array to doubles and calls CoordinateSystem.toReference(double[][]) and then returns that converted double array back as a float array. For efficiency, subclasses should override this implementation.
    
    Overrides:
    
    toReference in class CoordinateSystem
    
    Parameters:
    
    values - array of values assumed to be in coordinateSystem units. Input array is not guaranteed to be immutable and could be used for return.
    
    Returns:
    
    array of float values in reference coordinates and Units.
    
    Throws:
    
    VisADException - if problem with conversion.

```
  - getDefaultMapArea
```
public Rectangle2D getDefaultMapArea()
```
    Description copied from class: MapProjection
    
    Get a reasonable bounding box in this coordinate system. MapProjections are typically specific to an area of the world; there's no bounding box that works for all projections so each subclass must implement this method. For example, the bounding box for a satellite image MapProjection might have an upper left corner of (0,0) and the width and height of the Rectangle2D would be the number of elements and lines, respectively.
    
    Specified by:
    
    getDefaultMapArea in class MapProjection
    
    Returns:
    
    the bounding box of the MapProjection

```
public boolean getIsNeg180pos180()
```
  - setIsExtNeg180pos180
```
public void setIsExtNeg180pos180(boolean yesno)
```
    Will convert to external (incoming/outgoing) longitude range, ie. -180 to 180 back/forth to 0 to 360. Default is: external range is 0 to 360
  - getIsExtNeg180pos180
```
public boolean getIsExtNeg180pos180()

  - equals
```
public boolean equals(Object cs)

    Description copied from class: CoordinateSystem
    
    Indicates whether or not this instance is equal to an object (note must test for cs == null).
    
    Specified by:
    
    equals in class CoordinateSystem
    
    Parameters:
    
    cs - the object in question.
    
    Returns:
    
    true if and only if this instance equals cs.
