KB10743 - Feature for smoothing polylines and polygon boundaries.

The DK TGIS_Shape.Smooth method, which is a Catmull-Rom splines smoothing algorithm, can be used to smooth vector lines or polygon boundaries by adding additional, well placed, vertices to the line or polygon feature. (The TatukGIS Editor also supports this feature.)

The counterpart to TGIS_Shape.Smooth is the TGIS_Shape.Simplify property, a Douglas-Peucker vertice removal algorithm, which reduces the number of vertices in line or polygon shapes while striving to retain, within tolerance, the geometric integrity.
