Classes

This tab shows a list of 255 classes which are named according to the ISPRS standard. Every checked (selected) class will be visible in the point cloud and will therefore be used by the different analysis and selection tools. 

The name of a class as well as its color may be modified according to user preference. The class colors are useful when viewing the point cloud in “Color by Class” mode (see "point cloud display" for more information). The modifications are project dependent, so every project may have its own classes for its own needs.

The "Pts." column will show the number of points in each class, but must first be calculated by clicking on its checkbox.

There is also the posibility to create groups of classes. By checking the ckeckbox of "By Group" this feature will be enabled and you can start creating group of classes by clicking on the  button. 

If you want to share the list of your classes or groups with anyone you can export/import by clicking on /.
