Class MeasureInterpolatingVisitor<P extends C2D & Measured>

java.lang.Object

org.geolatte.geom.MeasureInterpolatingVisitor<P>

All Implemented Interfaces:

GeometryVisitor<P>

public class MeasureInterpolatingVisitor<P extends C2D & Measured>
extends Object
implements GeometryVisitor<P>

A GeometryVisitor that derives a Geometry by interpolating on the measure values of the visited Geometries.

Interpolation is used to determine any points on the 1-dimensional geometry with an m coordinate value between SM and EM inclusively. The implementation-defined interpolation algorithm is used to estimate values between measured values, usually using a mathematical function. For example, given a measure of 6 and a 2-point linestring where the m coordinate value of the start point is 4 and the m coordinate value of the end point is 8, since 6 is halfway between 4 and 8, the interpolation algorithm would be a point on the linestring halfway between the start and end points.
