Hi, I would like to know if it is possible to filter a point cloud into ground and non-ground points. In other words, is there a way to classify&nbsp;the point cloud&nbsp; so that&nbsp;all the points that represent the ground, i.e. the dirt and sand, are separated&nbsp;from the rest of the point cloud?

Hi Leo,

Here you will find more information about the automatic point cloud classification:&nbsp;[How to generate the Point Cloud Classification](https://support.pix4d.com/hc/en-us/articles/115004864586-How-to-generate-the-Point-Cloud-Classification)

It classifies the point cloud in&nbsp;one of the following predefined groups:

Ground  
Road Surface  
High Vegetation  
Building  
Human Made Object

The points that are erroneously assigned to a point group can be moved manually to the correct point group using the [Edit Densified Point Cloud](https://support.pix4d.com/hc/en-us/articles/202560499-How-to-edit-the-Point-Cloud-in-the-rayCloud#gsc.tab=0) option.

I hope it helps 🙂
