📢 Announcing keynotes for @Silvilaser23 We are honoured to welcome Yadvinder Malhi, Andy Waddington Hexagon Geosystems and Kate E. Jones 🦇 These promise to be great sessions that are "not just LiDAR and not just forests" but aim broaden to discourse on what can be achieved with #LiDAR!
Really fascinating to visit @wakehurst_kew and the Millennium Seed Bank @Kew_MSBUK yesterday to discuss their research agenda from seeds to ecosystems to Leverhulme Centre for Nature Recovery , thanks @Ed_Ikin and colleagues!
Trying to find trees in LiDAR data? Problem: 100s of algorithms but hard to assess their accuracy Solution: use segmented TLS to label trees in ALS, then compare algorithms. Paper: doi.org/10.1016/j.jag.… James Ball Phil Wilkes Kim Calders Mathias Disney @Silvilaser23
Are you attending British Ecological Society's conference this year? Interested in how #lidar can help answer your #ecology questions? Want some guidance on starting out with #3D tree data? 👉Then 'Intro to lidar for forest ecology' is the #BES2023 workshop for you! GIF credit Phil Wilkes
🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳 For those that need to segment trees from terrestrial LiDAR data, we present #tls2trees! Tested on 6 ha of Wytham Woods, we extracted 7615 trees using Centre for Environmental Data Analysis HPC! Try for yourself github.com/tls-tools-ucl/… 🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳🌳
🌲🌲some great coverage of our UK redwoods paper this week by Rebecca Morelle 🌲🌲 Thanks to all coauthors UCL Geography @KewScience KewGIS Find your local redwood redwoodworld.co.uk/locations.htm
We’ve been working in the #wetwoodland at @wakehurst_kew today installing dipwells for hydrological monitoring as part of the Wet Woodlands Research Network research network and supporting Steph Batten (she/her)’s PhD. I’m excited to see what the data show!
Branches were first stripped of their 🌿 then scanned in high-resolution. Full details of methods can be found in doi.org/10.1111/2041-2… Methods in Ecology and Evolution
Quote of the day from @wakehurst_kew ecosystem observatory launch: Trees are such good pollen and nectar sources that we should think of them as ‘sky meadows’! Highlight of the day was the wet woodland plot - see 📸 Thanks Phil Wilkes for inviting @WoodlandTrust
