I'm testing the new Segment Anything Model on satellite imagery. It works so well! Within 30 seconds I can get the footprints of all the objects of interest in a scene. Colab notebook below @EarthGenome

New #remotesensing and #plantdiversity research from our group out in @Drones_MDPI ! Led by @forestanu and me, and co-authored with @TACAGEM @SabineKasel and @ozdendro, we used #drones to quantify beta-diversity in temperate regrowth forests. @SciMelb

some result figures: DBH extracted from MLS, estimation subcanopy tree height and detect stags using MLS

Check the result of 12-month collaborative project with FWPA (https://t.co/it1oAjijLj ). Honored to be a part of this project and contribute the Tree-level analyses section (Fig10-17). #MLS #ALS #forestry #foresttech #lidar

April #GEDIVis entries bring on the May challenge competition! Here is an awesome 2020 entry from @neilssteven 🦧🌳 We are so excited to see what you come up with — make sure to tag @GEDI_Knights and use the hashtag #GEDIVis to enter :)

[Ruizhu Jiang @Jane_Ruizhu]

@venomox7 Thank you! That's a good idea! DJI also has a LiDAR sensor Drone Zenmuse L1 (https://t.co/Bn18HS9hvU) maybe can do a better work for this . We use the same sensor, but drone can cover larger area than human walking 😉.

[Ruizhu Jiang @Jane_Ruizhu]

Build my own Ultra-dens/ROS-SLAM LiDAR system with DJI Livox AVIA (https://t.co/qMQQhzL4xP) Works very well for urban parks 🥳 Ready for a test scan in the native forest #Lidar #dji #ros #mapping

[Ruizhu Jiang @Jane_Ruizhu]

@actSocial86 @rosorg We're developing our own SLAM code, so unfortunately I can't share our whole code with you till we get our paper published. But you can check DJI Livox Github first (https://t.co/FTdGrl4Jxm), such as "livox_mapping", you may get some codes you can start with.

New! #Jupyter Notebook tutorials at the NASA #ORNLDAAC show users how to search, download, and subset the new Global Ecosystem Dynamics Investigation (#GEDI) L4A Footprint Level Aboveground Biomass Density, Version 1 dataset. Check them out at: https://t.co/ofrkK30r6I

Can't believe this! I use lastools a lot. RIP Martin Isenburg.

[Geo Week News @GeoWeekNews]

Remembering Martin Isenburg, 1972-2021 Once you’ve spent even a little time in the laser scanning industry, you come across the work of Martin Isenburg. His LAStools and LASzip, freely available to anyone who’d like to use them through rapidlasso, are f… https://t.co/1um1f8MLJ5

[Simon @SimonGIS]

Is there any spatial content/APIs/Apps relating to #COVID19Aus that we could be pulling together somewhere for easier discovery + collab if things ramp up next week? https://t.co/DbKB8v0t0r

[Ruizhu Jiang @Jane_Ruizhu]

Did some photo editing for the multi-views of 360 camera photos #insta360 #360camera Looks much better!😄😁😆

Different angles for low fire severity plot.

Collecting field validation data for fire severity using 360 camera! Only one photo will capture all the information you need for one plot! 😊😊😊
