com.vividsolutions.jts.linearref.LengthIndexedLine
Supports linear referencing along a linear {@link Geometry}using the length along the line as the index. Negative length values are taken as measured in the reverse direction from the end of the geometry. Out-of-range index values are handled by clamping them to the valid range of values. Non-simple lines (i.e. which loop back to cross or touch themselves) are supported.

    Coordinate p = ll.extractPoint(index);
    return g.getFactory().createPoint(p);

  public static Geometry extractLine(Geometry g, double start, double end)
  {
    LengthIndexedLine ll = new LengthIndexedLine(g);
    return ll.extractLine(start, end);
