Interface ImageDatum

All Superinterfaces:

Datum, IdentifiedObject

@UML(identifier="CD_ImageDatum",
     specification=ISO_19111)
public interface ImageDatum
extends Datum

Defines the origin of an image coordinate reference system. An image datum is used in a local context only. For an image datum, the anchor point is usually either the centre of the image or the corner of the image.

Note: the image datum definition applies regardless of whether or not the image is georeferenced. Georeferencing is performed through a transformation of image CRS to geodetic or projected CRS. The transformation plays no part in the image datum definition.
