LIDAR scans of 2 veteran oaks


Recommended Posts

LIDAR scans taken of a couple of old oaks at Hampstead Heath.

 

Part of a project looking at range of different trees in the capital with a focus on urban biomass and carbon storage.

 

Below is a 2D image from the scan, click the red link below the image to get the whole 3D version.

This next clip shows the density of the secondary woodland that has grown up around around the two old trees over the last century.

 

 

This is how they used to look.....

Fantastic! Loved having a fly about on the 3D model. The resolution of the main stem and branch framework seems pretty good. What’s the minimum diameter of twigs picked up? 

 

Love the black and white photo of the trees before they were enclosed by the woodland - another reminder that tree time blows my perception of time out of the water! 

 

What do you see as the key uses for this kind of technology David?

Not entirely sure Paul, I haven't heard the UCL guys talking about using it for anything other than biomass measurement at this time, but Kew are looking at canopy dynamics and pruning models with it.

 

The accuracy of the measurements (appears to record everything down to leaves and twigs) could perhaps be utilised to record significant limb subsidence & root plate tilt?

 

Perhaps even helping with identifying surrounding canopies for targeted halo pruning/felling.

 

 

I just like the way that you get a 3D snap shot portrait of a tree (or trees) that can be kept in perpetuity as a record of their presence.

 

Would be fantastic to record all the champion trees and ancients with this tech.

Just think, in another 10 years time this technology will probably be available on everyones phone.  We'll be able to factor in quantity of waste removal at the quote stage  :D

Currently about 160K for the laser so would need a sharp reduction in size and price before it becomes available on the mobile market :D

Short article in Pro Arb about the teams findings.

 

http://proarbmagazine.com/urban-trees-absorb-carbon/?platform=hootsuite

 

“The team found that Hampstead Heath stores up to 178 tonnes of carbon per hectare, which is catching up to tropical rainforests that contain on average around 190 tonnes of carbon per hectare.”
