Simplify
This function is used to simplify the selected geometry. In short, it simplifies to a single point, any two points who's distance apart is smaller than the selected threshold.
Usage
Geometry type
This allows the user the preference of the geometry type he will be selecting. The actual simplification algorithm is the same in all cases.
Tolerance
The value for which this function will consider that two points are identical and should be fused. Any two points closer than that will be merged throughout the list. All the connections will be regenerated.
