# Classify By Class

**Classify By Class** moves all points contained in the list of **Input Classes** and reassigns them to the **Output Class**. In the example below, all points in class 02 (Ground), will be reassigned to the 01 (Unclassified) class:

{% hint style="info" %}
If a selection is present, **Classify By Class** will only change the class of selected points. This can be useful, for instance, when assigning a [**Cloud Query Tool**](/spatialexplorer-8-and-9/user-interface/toolbars/data-visualization.md#cloud-script-tool) selection to a class.&#x20;
{% endhint %}
