How to automatically classify ground points when creating a DEM from mobile mapping data?

I am currently facing challenges in the classification of points while generating a Digital Elevation Model (DEM) from mobile mapping data. Specifically, I am encountering difficulties in automatically classifying ground points, as all points are currently grouped into a single class.

Could someone kindly advise on the appropriate parameter settings to enable the automatic classification of ground points in this scenario?

Your insights and guidance would be greatly appreciated.

Thank you in advance.


  • Parameter settings in the automatic classification tools help tell the tool what to expect in your specific data. Descriptions of these settings and what they do can be found on this page in the knowledge base.

    This blog has the older dialog, but the settings are still the same. This relates to the Gridded method of ground and noise classification in the new dialogs. Troubleshooting Lidar Ground Classification
