Split by class

Split by class command can be used to split groups if points in the group belong to different classes. This may happen, for example, if different objects are close to each other, such as poles and vegetation. Grouping may result in one group for a pole and close-by vegetation.

To split groups by class:

1. Select Split groups by class command from the Group pulldown menu.

This opens the Split Groups by Class dialog:

split_groups_by_class

2. Define settings and click OK.

This assigns a new group number to points in the selected class(es), if points from another class are in the same group.

Average xy - groups are classified if the average xy point is inside.

Majority of points - groups are classified if the majority of points is inside.

All points - groups are classified if all points are inside.
