Examples of GridGeometry2D

org.geotools.coverage.grid.GridGeometry2D
Describes the valid range of grid coordinates and the math transform, in the special case where only 2 dimensions are in use. By "in use", we means dimension with more than 1 pixel. For example a grid size of 512×512×1 pixels can be represented by this {@code GridGeometry2D} class (some peoples said 2.5D) because a two-dimensional gridcoordinate is enough for referencing a pixel without ambiguity. But a grid size of 512×512×2 pixels can not be represented by this {@code GridGeometry2D}, because a three-dimensional coordinate is mandatory for referencing a pixel without ambiguity. @since 2.1 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD) @see ImageGeometry @see GeneralGridGeometry
