You can do PROJECTIONS in ArcGIS or there are freebies on the internet to convert sets of coordinates.

It is dependent upon the quality of the ground estimate for that cell. There could be a hump, or the Lidar data may smooth the topography to the tree height's benefit. However, from what I've seen so far, my bare ground outliers are all above ground. I'm not sure that I could convert the coordinates easily. I'd have to enter them into a GPS in one setting, change the settings, and then read them back. I'll see if the LiDAR software can read .shp files. I'll look into it.

I took a waypoint for a 127' Quercus rubra and another for the 20.5' cbh poplar. In between the two is a 150+ poplar I did not way point. I could use ArcGIS to convert the projection to NAD83State Plane NC 3200ft and email it too you as a .shp or a kml file (if I could figure that out) if that would be helpful. I probably wouldn't get to it until monday. If a WGS 84 projected file would be good enough, I could send that to you very easily. Anything anywhere near 171' would be phenomenol!
