Which companies in Maine (if any) do ground-based LiDAR surveys that could produce a georeferenced 3D model (we use ArcGIS, not CAD) of an eroding bank?  Part of the survey area is unvegetated, but part of it is vegetated.   I am interested in getting a general estimate of cost for this on a job we are currently doing with a total station survey.  I'm wondering if ground-based LiDAR would be less cost & labor intensive or not.

Thanks!
