It's working well, but my data needs cleaning up.

If so you should use Bentley Descartes' Ground Extraction tool to first extract the ground points from your LIDAR data before importing the point cloud into Geopak.</p> <p>Thanks,</p> <p>Mathieu</p> <p></p> <p><img src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/343228/pastedimage1534383663140v1.png" alt=" " /></p><div style="clear:both;"></div>
