@UML(identifier="CV_FootPrint",
     specification=ISO_19123)
public interface FootPrint

The presentation of an observed or measured space surrounding a sample point in the context of some external coordinate reference system.


Method Summary
 GridPoint getCenter()
          Returns the grid point to which this foor print corresponds.
 Geometry getGeometry()
          Returns the geometry that shapes the foot print.
 

Method Detail

getGeometry

@UML(identifier="geometry",
     obligation=MANDATORY,
     specification=ISO_19123)
Geometry getGeometry()
Returns the geometry that shapes the foot print. In the simplest case this can be a point, but it can also be a disc, sphere or hypersphere


getCenter

@UML(identifier="center",
     obligation=MANDATORY,
     specification=ISO_19123)
GridPoint getCenter()
Returns the grid point to which this foor print corresponds.

TODO:
his role name in ISO 19123, "center", is a misnomer. By definition, the sample point represented in the same external coordinate reference system as the footprint, is the "center" of the footprint. This "center" attribute associates the footprint with a grid point, which represents only the index into the grid. This implementation specification, therefore, has renamed the association role to "index".
