Re: Hello Everyone - Chris Strother

Welcome Chris!

Indeed, NTS members are in possession and processed much of the TN LiDAR. Recon trips have been both highly disappointing (crown abnormalities, heavy lean, steep slopes) and exciting- several tuliptrees over 180' and a super tall bitternut hickory (sorry- don't recall the numbers). In old-growth forests the TN LiDAR is highly unreliable based on the few trips so far. However, in second-growth it is comparable to more coarse NC coverage and has us hopping with excitement. The NC Tuliptree Study has just been extended through 2014 at which time we may move to the TN side. You can search the BBS for posts of all these trips,

Re: Hello Everyone - Chris Strother

Welcome aboard Chris! I'm a fellow member just down the road in Atlanta. I second Bob's comments. You're in good company with the best of the best "big tree hunters" in the east. Heck, Will Blozan has even helped climb, measure and volume map the giant sequoia's out west with none other than Steve Sillett.

Do you plan to "ground truth" the Lidar hits? I know that ground expeditions are sometimes (often?) a let down when you find out trees are leaning over a deep ravine and thus giving false height readouts on Lidar. I can almost guarantee you that Will, Jess, Josh, etc. will have great insight into the areas where you noticed high numbers.

Happy to have you here and I hope that you post often. Best of luck with your research,
Eli

Re: Hello Everyone - Chris Strother

Chris,

Welcome aboard. I think it is safe to say that we're all interested in your research and results and would be interested in what you are finding. We use LIDAR quite a bit to identify tall tree hotspots and then go in and ground-truth them. Will Blozan, Josh Kelly, Michael Davie, Jess Riddle, and others are heavily involved in verifying LIDAR hits. They can discuss with you where they find the LIDAR data to be most accurate and where they've encountered problems and the nature of those problems. It was from a LIDAR hit that they discovered and then confirmed the 191.9-foot tall Liriodedron tulipifera in NC. The tree was climbed and tape-frop measured. You may have read about that.

Again, welcome aboard.

Bob
