One Click Geometry (FCSI)

This functionality simplifies the editing of geometry and underlying topology. More Information

Douglas-Peucker (GE Class C contact your salesperson)

Fouglas-Peucker is a technique for thinning lines whilst retaining the general shape. As almost a reverse-peucker, a useful routine called make_wiggly() has been developed by the Chairman, Richard Newell to increase the number of points in a line. This routine is especially useful for generated pseudo data, such as coastlines, soil boundaries , etc.

The diagram illustrates the use of make_wiggly() and douglas_peucker() on a simple piece of geometry. The original contains only five points. Using make_wiggly() with two different degrees of wigg'lyness yields the second and third lines (from left to right) . Note, make_wiggly() takes an optional second parameter - the stop criterion. Taking the most wiggly of those, and applying douglas-peucker yields the right most lines - again, two values have been chosen, where the larger tolerance gives a much rougher result.

Curve Fitting (GE Class C contact your salesperson)

An enhanced trail menu allowing three point arcs and curve fitting through a number of points. (Smallworld Product and Services Guide)

Multi Dimensional Geometry (FCSI)

This functionality allows you to import and view multi dimension geometry into Smallworld. Multi dimensional geometry could be LiDAR, Leak Survey Data, and other time/value data . More Information

Elevations an Profiling (FCSI)

This functionality allows you see and interact with terrain data. This provides several tools to import terrain models, create contour lines and annotate them and view a profile of a linear feature with feature crossing information. More Information

Buffer Tool (FCSI)

This simple to use module allows you to easily create and search buffer geometry quickly and efficiently. More Information

3 Dimensional Topology (FCSI)

Extension to Smallworld CST's topological engine to support the third dimension. These algorithms automatically update the connected features' 3D coordinate. More Information
