Hello All,

Can anyone help me with the workflow to Take Lidar Files from Opentopography.org and create an existing ground surface? I can do this using civil 3d, but would like to figure it out in Trimble. 

I have been able to import a contour shape file that has contour elevations stored as an attribute, but the actual elevation is 0.00 for the line. 

I am not dead set on using the data from open topography.org, just looking to create existing ground surfaces without the need to survey the property.

Thanks in advance.
