| + | === Classified point cloud === | ||
| + | |||
| + | Restrict or filter specified point cloud classes to be used for feature detection. | ||
| + | * Integer values, comma separated. | ||
| + | * If no class is specified all classes are used, no class is excluded. | ||

| === Smoothing === | === Smoothing === | ||
| + | A moving average algorithm can be used to smooth line features. The average of the 4 neighboring points and the current position are used to calculate an updated position of a point or vertex. We allow 6 levels of smoothing, which corresponds to how many times the moving average is used. Level 0 means no smoothing is done, level 5 means the line points are moved 5 times. | ||
| + | |||
| + | === Get Point Cloud === | ||
| + | |||
| + | Export the feature point cloud as a selection linked to the source point cloud resource file, or as a new point cloud resource file. | ||
| + | Significant time is required to create point cloud selection. Point cloud file and derived vector data creation (e.g. outline on ground) is only possible if selection is created. | ||
