This is already being trialed in forestry, it’s super site dependent and the tech is almost there for incredibly dense forests. I would imagine it’d work well in the uk woodland. Practical skills will always be required but it’s true that things are being lost. In NZ we are loosing a lot of our timber falling experts as everything that can be mechanized has to be in a lot of forests due to health and safety regulations. Crews are starting to loose that expertise onsite. I come from a very practical background, 15 years on the tools doing various climbing things here there and everywhere but I’m really excited about this new innovation and integration into my daily work.

It’s incredibly accurate, this site was pretty open so that accuracy is expected. On busier sites that may stretch out a small margin. To be fair, it was probably a more consistent measurement than what we did with the tape 😂
-
An update for those of you that are interested. We’ve been working on a lot of things (not so arb-specific bar the machine learning for trees, but that’s another post). We’ve been testing our unit against field measurements and have had some pretty spectacular results. We can export one of these for each tree onsite.

The description for those that don’t go through to YouTube. @KōwhaiAero helping out on a site proposed for #helicopter extraction. Using lidar equipment and GIS software they were able to isolate the proposed trees for lifting and provide a site map for planning. This information can be shared remotely so the team can familiarize themselves with the site, create a plan, efficiently deliver required materials for each individual tree.

Here's a link for some of the recent work we’ve been doing. This job is not my own, it’s for a friend. He’s asked me to consult and to dust off the harness if it goes ahead. Great to use our scanner on, we will be extracting a lot of information from this one.

I don’t think I’ll be able to make it Mark. I’m flying back on the 22nd so it’s cutting it a bit close. Flick me a message on Facebook, I can keep ya updated.
-
Yes Mark we have purchased both the drone and the LIDAR unit.

We have a national lidar database also but it has the same issues as you described above. I have worked on a tender that used this to pick out trees for a runway clearance. The deciduous trees were off by anywhere up to five meters as the method of scanning wasn’t picking up on the apical buds but rebounding off bigger branches lower down. It wasn’t as useful as what they hoped it would be. the lidar database is accurate to a meter or two (off the top of my head) which is alright for some things but it doesn’t have the accuracy and reliability needed for more specific tasks. It is however a fantastic tool to have available to use as you’ve described above.

Hey Mark, With Pinus radiata it’s pretty consistent. Our green weight for this species has been used frequently in the last three years. It’s a specific type of growth and situation which makes them a different weight to a regular forestry pine. Spring time we would expect to see a small bump up in weight but we have buffers which account for this anyway. with Mac’s Its still 50/50 if it’s going to be bone dry and light as a match stick or way too heavy 😂
-
No, we aren't there yet Jules haha. I don't think anything out there is that precise. It is however accurate to 4cm on vertical and 5 cm for horizontal. The measurements above are what has been extracted from the point cloud, these measurements fall under those accuracy parameters that I described above. There are multiple other factors that can alter those measurements and that's to do with the clarity of the point cloud and how its processed.
-
Hey Jules, yes that's a great way to use the tech. what your college is thinking about is actually what I've been using it for. I have been testing this on a big block of pine trees that are scoped to be heli lifted out (I will attach some photos of how it can be presented). I worked with a local company to compile this data into something useable for us... there were limits as some of the stems weren't completely picked up by the first scan but we have since gone back and have corrected these with a more thorough scan. I can share these as the data on this one isn't exact. scanning parks would be much easier as there's a huge amount of free space around the trees and the canopies are more defined.

Hey everyone, For those who don't know me, I’m Jesse Coleman, and I run a company based in New Zealand. We’ve recently acquired a LiDAR unit and have begun exploring its potential. Initially, we aimed to use it for data acquisition, estimation, and presentations for larger-scale helicopter work. However, we've been so impressed with the technology and its results that we're now incorporating it into our day-to-day services. I’d love to hear from those of you who are already using this tech. Where have you found it to be game-changing? Whether it's tree inventories, site scanning, harvest models, or something else, I’m interested to hear more about how you're utilising LiDAR and where you see its future heading. Looking forward to your insights.

That bridge is to small , I said that when i first saw it. I talked to a guy from courant a month or two about that bridge and they said they have put a new one on. Glad no-one is hurt.

Just a vt works fine, it doesn't lock up.

From my understanding this will apply to the whole of Europe, I would say I disagree but i kinda think they've done it well. I wonder if any other tethers will be allowed? isc pulled a pretty slick move there. they will be selling a huge amount of tethers now.
