Laserscan of a big Open Grown Oak

Here's a pop-sci type demonstration of a laserscan of a big English Oak tree (~15' cbh).  Supposedly they calculated a total branch length 12Km(7.2miles) on the thing.

(~5 minutes,  You can can back up 1 minute for a very ENTS-not-approved measurement of the CBH/dead reckoning of its age at ~200 yrs using a ball of twine and measuring the length with a guy's arm-span from his nose)

Randy-   The Laser scan imagery is really cool. I wonder how much an instrument like that would cost?  Larry

I dunno....Google searches keep dead-ending on pages that say 'Call for Price'.  How good are you at research grant applications again?

More seriously, I did think it was noteworthy in that they seemed to have automated Van Pelt's crown surveying+rebuild in excel methods he showed us at Congaree.
