/**
 * Provides a navigated VisAD DisplayImpl for displaying data.
 * The Projection or MapProjection provides the transformation from
 * lat/lon space to xy space.  There are three modes that can be used
 * with this display - MODE_3D (Java 3D), MODE_2Din3D (2D in Java 3D),
 * MODE_2D (Java 2D).  Performance is better in Java 3D modes. In the 3D
 * mode, RealType.Altitude is mapped to the display Z axis.

 * Any displayable data must be able to map to RealType.Latitude,
 * RealType.Longitude and/or RealType.Altitude.

 * Provides a navigated VisAD DisplayImpl for displaying data.
 * The Projection or MapProjection provides the transformation from
 * lat/lon space to xy space.  There are three modes that can be used
 * with this display - MODE_3D (Java 3D), MODE_2Din3D (2D in Java 3D),
 * MODE_2D (Java 2D).  Performance is better in Java 3D modes. In the 3D
 * mode, RealType.Altitude is mapped to the display Z axis.

 * Any displayable data must be able to map to RealType.Latitude,
 * RealType.Longitude and/or RealType.Altitude.
