New paper by Wout Cherlet & @qforestlab.bsky.social team led by @kimcalders.bsky.social, comparing tree extraction methods from TLS data. TL;DR it's hard to automate, ecosystem dependent & parametric approaches currently outperform DL www.sciencedirect.com/science/arti...

The most well-know use-case of optical fibres is internet. We show that it actually allows us to measure microclimate temperatures at the ultra-high resolution of 25 cm! Since these fibres can be very long, up to 30 km (!), this novel means of environmental monitoring seems super promising.

Our new perspective on what TLS can (& can't) do in forest research www.nature.com/articles/s41... - led by Eduardo Maeda w lots of great colleagues including @kimcalders.bsky.social @emilyrlines.bsky.social @louiseterryn.bsky.social @benjaminbrede.bsky.social (apols for any I don;t have @ for)

I like big trees and I cannot lie. Great bit of work by @kimcalders.bsky.social @louiseterryn.bsky.social and colleagues using innovative climbing and scanning approach. Stunning illustration of tree structural and biodiversity complexity zslpublications.onlinelibrary.wiley.com/doi/full/10....

🆕 The first stunning images from our groundbreaking #Biomass satellite mission have been released – they mark a major leap forward in our ability to understand how Earth’s forests are changing and exactly how they contribute to the global carbon cycle 🌳🌍 www.esa.int/Applications...

Our new perspective on the use (& misuse) of what we're calling virtual forests (rather than digital twins!), for forest change from space, led by @kimcalders.bsky.social w many great colleagues 🔭 🧪🔬 www.sciencedirect.com/science/arti...

Sensors, scientists and sunshine. Thanks for the great Strucnet vegetation structural dynamics meeting @kimcalders.bsky.social.

Strucnet meeting organised by @kimcalders.bsky.social very much fun!

The #EucFACE canopy has finally recovered from the 19-20 drought and the 21-22 floods. Beautiful time for new Lidar scans! @westsyduhie.bsky.social @kimcalders.bsky.social

Job Alert - Come work with us at @qforestlab.bsky.social! I'm hiring a postdoctoral fellow in vegetation remote sensing and radiative transfer to work on my @erc.europa.eu SPACETWIN project (spacetwin.ugent.be). More info ➡️ www.ugent.be/en/work/scie... Deadline: March 7

We are currently in Patagonia for our @ercresearch.bsky.social project #SPACETWIN, looking at the impact of caterpillar (Ormiscodes amphimone) disturbance on the Nothofagus forests. This is a @qforestlab.bsky.social collaboration with the team of Roberto O. Chávez from PUCV in Valparaíso [1/4]

@qforestlab.bsky.social There are so many leaf-wood separation algorithms, don't know how to choose? Our latest work (from @qforestlab.bsky.social ) has addressed this issue by providing a robust evaluation framework. Interested? please check our paper: authors.elsevier.com/a/1kKNW7qzT3...

Wouter & Wout from @qforestlab.bsky.social are currently collecting TLS data at the Caxiuanã through-fall exclusion (TFE) experiment for our #ERC SPACETWIN working with our Brazilian collaborators and Patrick Meir. Continuing the TLS time-series that was initiated by @matdisney.bsky.social [1/2]

Important finding for impact modelers by @kornhuber.bsky.social et al.: Climatic extremes change faster/ more severely than anticipated by climate models. The consequences anticipated with impact models (based on climate model-driven forcings) might thus be conservative. www.pnas.org/doi/10.1073/...

The first month of our field campaign in the Queensland Permanent Rainforest Plots (@QPRPaus - ) has been a success with 6 plots already completed and 10 more to go in the coming weeks! [1/5]

It was great having Maurice Leponce give a guest lecture in our BSc course on Ecology, covering Tropical forest biodiversity: large-scale inventories, canopy access, and the role of natural history museums. Great inspiration for our students!

Experimental work on nondestructive monitoring of the dielectric permittivity dynamics of trees for @ERC_Research SPACETWIN with the installation of 2 wood penetrating radars. In collaboration with François Demontoux & Ludovic Villard.

Lathamus Keep, a Tasmanian giant Eucalyptus globulus (+80 m tall) in the Huon Valley scanned by terrestrial and canopy laser scanning. At 8 m high, it’s diameter is still an astonishing 3 m! View it in 3D here: w. @TerraLuma @l_hambrecht @BarbaraDhont

Vacancy! Join our team as a postdoctoral fellow (2yr position) on our newly funded @FWOVlaanderen project with @LouiseTerrynn and @shaunlevick! Info: Apply by Feb 9:

What a great two weeks in Tasmania with @TerraLuma and @l_hambrecht mapping giant and old trees for @ERC_Research SPACETWIN. We managed to scan 10 giants (with some well over >80m in height).

I have arrived in Big Tree State Tasmania! Working with @UTAS_ @TerraLuma on giant tree mapping for @ERC_Research SPACETWIN, with help from @CorigJan, @l_hambrecht & the tree projects. More soon!

The first leg of my Australian fieldwork trip was a success with a range of benchmark scans covering various forest structures with our RIEGL TLS and the autonomous LEAF scanners from ESS Darius Culvenor. Glad to have some hands-on training for LEAF installment from Darius!

Wrapping up 2 weeks of fieldwork with @WoutCherlet in Brazil's Atlantic Forest at @araca_project and @antonelli_lab. Our main goal was to map the well-studied ficus tree from the ground & up in the canopy! [1/4]

Wouter & Zane are currently collecting data at the Caxiuanã through-fall exclusion (TFE) experiment for our @ERC_Research SPACETWIN working with our Brazilian collaborators and @pwmeir @EdinburghUni and further building the TLS time-series that was initiated by @mathiasdisney

New paper led by @Chang_Liu_RTM on the impact of # of individual reconstructed trees on stand level 3D scenes for radiative transfer modelling @WythamWoods . Full paper:

The wind conditions have not often been on our side this summer, but the coming days look very promising. @barryshilin and I will continue scanning our #bosland plots for #SPACETWIN and #projectWEAVE with @corneliussenf. Also check out the new graphics from @StudioKnets 👇

Very pleasant to have a #LOT meeting in the museum of natural sciences and quickly check out the dinosaurs too!

For an MSc project we are looking for any TLS data of #Oak trees to complement our own dataset. Reach out if you have some data that you are willing to share with us! (Any high-quality point cloud data is very welcome!)

Mapping out 3 x 1 ha sites and installing microclimate loggers (+ boar protection!) in #bosland w. @LouiseTerrynn. One more site is to be set up in a few weeks and many more sensors will be installed over the next months for @FWOVlaanderen #projectWEAVE with @corneliussenf

Next week we will start the first larger TLS field campaign supported by the @ERC_Research #SPACETWIN team in beautiful Berchtesgaden with @corneliussenf & @RupertSeidl!

Last week we finalised the training and calibrated ourselves in #Bosland before starting the fieldwork for our @ERC_Research SPACETWIN project. First trip will be later this month to Berchtesgaden with @corneliussenf and @RupertSeidl.

Good weather & good discussions at the first StrucNet User Workshop in @GFZ_Potsdam! More information on this very soon. Check our recent publication here: or catch my or @benjamin_brede presentations at #LPVE23 and @Silvilaser23 later this year.

Always nice to be back @ucl. Even nicer to have @prof_plewis talk about his favourite equations. Made me relive the vegetation science course again!

Great to have @Toby_D_Jackson visiting @CAVElab_UGent and learning more about forest disturbances and dynamics!

Check out our new publication where we propose StrucNet: a global network for automated vegetation structure monitoring: [1/4]

Our open-source teaching materials from the COST action @3DForEcoTech summer school are online! Hopefully a useful resource for all, but especially for educators who want to include UAV/TLS/mobile laser scanning or photogrammetry in their teaching. ➡️

The first field campaign of the year is currently going on. @jasperfeyen is back in Suriname for more #mangrove scans!

It's my @FbwUGent inaugural lecture today - you can still join!

Major update on the @WythamWoods virtual model: Version 5 (on master) fixes an error where the LAI was twice as large as it should be (created in version 3). If you have a local copy of the model, we encourage you to update your files:

Final day of training at our @3DForEcoTech @COSTprogramme summer school in Helsinki. Today's focus was mostly on photogrammetry and iphone lidar. Quite happy with the positive feedback at the end - thanks to all the trainers who made this possible!
