Smoothen points is a command that smoothes the attributes of points relative to adjacent points. Until recently, the modifiable point attributes were elevation, intensity, or color. The elevation option could be used to iteratively adjust elevation values of points using plane-of-best-fit equations to result in a smoother surface. The intensity option could be used to average the intensity values of points with their neighboring points to help make better looking intensity images. In a similar manner, the color option could be used to average the color values of points with their neighboring points to help make better looking 3D colorized point clouds.
Starting with TerraScan version 017.001, a new smoothen XYZ option was added to the Smoothen points command. This XYZ option modifies points so that they better match a 3D surface. This option can be used as an optional step when processing noisy data such as a photogrammetric point cloud or data from low quality laser scanners.
