extractPoint method
Computes the {@link Coordinate} for the point on the line at the given index. If the index is out of range the first or last point on the line will be returned. The Z-ordinate of the computed point will be interpolated from the Z-ordinates of the line segment containing it, if they exist.
@param index the index of the desired point @return the Coordinate at the given index
Implementation
Coordinate extractPoint(double index) {
LinearLocation loc = LengthLocationMap.getLocationStatic(linearGeom, index);
return loc.getCoordinate(linearGeom);
}
