Interface GeodesicString

All Superinterfaces:

CurveSegment, GenericCurve

All Known Subinterfaces:

Geodesic

@UML(identifier="GM_GeodesicString",
     specification=ISO_19107)
public interface GeodesicString
extends CurveSegment

Sequence of geodesic segments. The interface essentially combines a Sequence<Geodesic> into a single object, with the obvious savings of storage space.

Since:

GeoAPI 1.0

Method Summary

Modifier and Type	Method and Description
List<Geodesic>	asGeodesics() Decomposes a geodesic string into an equivalent sequence of geodesic segments.
PointArray	getControlPoints() Returns a sequence of positions between which this GeodesicString is interpolated using geodesics from the geoid or ellipsoid of the coordinate reference system being used.
CurveInterpolation	getInterpolation() The interpolation for a GeodesicString is "geodesic".

Method Detail

getControlPoints

@UML(identifier="controlPoint",
     obligation=MANDATORY,
     specification=ISO_19107)
PointArray getControlPoints()

Returns a sequence of positions between which this GeodesicString is interpolated using geodesics from the geoid or ellipsoid of the coordinate reference system being used. The organization of these points is identical to that in LineString.

Returns:

The control points.

getInterpolation

@UML(identifier="interpolation",
     obligation=MANDATORY,
     specification=ISO_19107)
CurveInterpolation getInterpolation()

The interpolation for a GeodesicString is "geodesic".

Specified by:

getInterpolation in interface CurveSegment

Returns:

Always CurveInterpolation.GEODESIC.

asGeodesics

@UML(identifier="asGM_Geodesic",
     obligation=MANDATORY,
     specification=ISO_19107)
List<Geodesic> asGeodesics()

Decomposes a geodesic string into an equivalent sequence of geodesic segments.

Returns:

The equivalent sequence of geodesic segments.
