public interface FootPrint

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

Since:

GeoAPI 2.1

Method Summary

GridPoint	getCenter() Returns the grid point to which this foot 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.

Returns:

The geometry that shapes the foot print.

getCenter

@UML(identifier="center",
     obligation=MANDATORY,
     specification=ISO_19123)
GridPoint getCenter()

Returns the grid point to which this foot print corresponds.

Returns:

the grid point to which this foot 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".
