Interface RectifiedGrid

All Superinterfaces:
GridPositioning, RectifiableGrid

@UML(identifier="CV_RectifiedGrid",
     specification=ISO_19123)
public interface RectifiedGrid
extends RectifiableGrid

Grid for which there is an affine transformation between the grid coordinates and the coordinates of an external coordinate reference system. A rectified grid is defined by an origin in an external coordinate reference system, and a set of offset vectors that specify the direction and distance between grid lines within that external CRS.

NOTE: If the coordinate reference system is related to the earth by a datum, the grid is a georectified grid.

Constraints:


Method Summary
 CoordinateReferenceSystem getCoordinateReferenceSystem()
          Specifies the coordinate system into which this object transforms coordinates.
 List<double[]> getOffsetVectors()
          Returns the offset vectors that determine the grid spacing in each direction.
 DirectPosition getOrigin()
          Returns the origin of the rectified grid in an external coordinate reference system.

Method Detail

getOrigin

@UML(identifier="origin",
     obligation=MANDATORY,
     specification=ISO_19123)
DirectPosition getOrigin()
Returns the origin of the rectified grid in an external coordinate reference system.


getOffsetVectors

@UML(identifier="offsetVectors",
     obligation=MANDATORY,
     specification=ISO_19123)
List<double[]> getOffsetVectors()
Returns the offset vectors that determine the grid spacing in each direction. The vectors are defined in terms of the external coordinate reference system.


getCoordinateReferenceSystem

@Extension
CoordinateReferenceSystem getCoordinateReferenceSystem()
Specifies the coordinate system into which this object transforms coordinates. ISO 19123 only specifies this association on the ReferenceableGrid type, but it is promoted to this superclass because it is required by both ReferenceableGrid and RectifiedGrid. In the context of the RectifiedGrid type, the coordinate reference system attribute inherited from grid positioning shall be derived from the Coordinate Reference System association of the origin.
