Interface ImageCRS

All Superinterfaces:

CoordinateReferenceSystem, IdentifiedObject, ReferenceSystem, SingleCRS

@UML(identifier="SC_ImageCRS",
     specification=ISO_19111)
public interface ImageCRS
extends SingleCRS

A 2-dimensional engineering coordinate reference system applied to locations in images.

Note: image coordinate reference systems are treated as a separate sub-type because a separate user community exists for images with its own terms of reference. Furthermore, image datum contains a property not relevant to other engineering datums.

This type of CRS can be used with coordinate systems of type CartesianCS or AffineCS.

Since:

1.0
