Classify Noise

Classify Noise is an isolated point filter. This means that any points without a sufficient number of neighbors (Neighbor Count) within a given distance (Search Radius) will be assigned to the Output Class, in this case the Low Point (noise) class. This is ideal for classifying sparse noise points that occur mid-air or far below ground.

In the example below, all point classes are analyzed and any points without at least 10 neighbors within 1 m (3D distance) will be assigned to the Low Point (noise) class:
