@UML(identifier="CV_GridGeometry", specification=OGC_01004) public interface GridGeometryDescribes the geometry and georeferencing information of the grid coverage. The extent attribute determines the valid grid coordinates and allows for calculation of grid size. A grid coverage may or may not have georeferencing.Warning — this class will change
Current API is derived from OGC Grid Coverages Implementation specification 1.0. We plan to replace it by new interfaces derived from ISO 19123 (Schema for coverage geometry and functions). Current interfaces should be considered as legacy and are included in this distribution only because they were part of GeoAPI 1.0 release. We will try to preserve as much compatibility as possible, but no migration plan has been determined yet.

All Methods Instance Methods Abstract Methods Deprecated Methods Modifier and Type Method Description
getExtent()The valid domain of a grid coverage.
getGridToCRS()Returns the conversion from grid coordinates to real world earth coordinates.
@UML(identifier="gridRange", obligation=MANDATORY, specification=OGC_01004) GridEnvelope getExtent()The valid domain of a grid coverage. The lowest valid grid coordinate is often (but not always) zero. A grid with 512 cells typically have a minimum coordinate of 0 and maximum of 512, with 511 as the highest valid index.Note: the attribute name in the OGC 01-004 specification was "
gridRange", while the ISO 19123 specification uses "
extent" for similar information. This interface uses the ISO name both for consistency with ISO interfaces, and because the range term is already used by ISO 19123 for a different meaning.

@UML(identifier="gridToCoordinateSystem", obligation=MANDATORY, specification=OGC_01004) MathTransform getGridToCRS()Returns the conversion from grid coordinates to real world earth coordinates. The transform is often an affine transform. The coordinate reference system of the real world coordinates is given by the
Coverage.getCoordinateReferenceSystem()method and maps to pixel center.
