@UML(identifier="CV_SegmentedCurveCoverage",
specification=ISO_19123)
public interface SegmentedCurveCoverageModel phenomena that vary continuously or discontinuously along curves, which may be elements of a network. The domain of a segmented curve coverage is described by a set of curves and includes all the direct positions in all of the curves in the set.
Arc-length parameterization of a curve simplifies interpolation between direct positions on the
curve. Representation of phenomena that vary discontinuously along a curve requires segmentation
of the curve into regions of continuous variation. Such segmentation is also simplified by
arc-length parameterization. Curve supports arc-length parameterization. In particular,
the operation:
GenericCurve.getParamForPoint(org.opengis.geometry.DirectPosition)
returns the arc-length distance from the start point of the curve to the input direct position.
A segmented curve coverage operates on a domain composed of curves. It is
composed of a set of ValueCurves, each of which maps feature attribute values to
position on a curve.

Set |
evaluate(DirectPosition p,
Collection<String> list)
Returns a set of records of feature attribute values for the specified direct position. |
Set<ValueCurve> |
getElements()
Returns the set of value objects used to evaluate the coverage. |
InterpolationMethod |
getInterpolationMethod()
Returns the interpolation method to be used in evaluating the coverage. |
