📢🌳🛰️Sharing new paper "Towards a global understanding of tree mortality" from the @treemortality.bsky.social network. Shout out to Cornelius/Adriane/Tom for leading this.
(From having fun with trees in the field to psychodelic-black-mirror-digital trees by the end 😅)

📢🛰️Sharing our new paper on Monitoring changes of forest height in California led by Dr. Favrichon

🔥 We assess the potential of mapping forest height using deep learning and 10-m satellite data and show how wildfire is the major driver of disturbance

I invite you for my talk about 'Mapping tropical forest degradation in high resolution with deep learning' at the EEBIOMASS virtual workshop Monday December 9

register : survey.academiccloud.de/index.php/24...

I will not be at AGU this year, but still I've got a talk to give at the same week! 😆

fazendo alguns testes pra mapear ganho de floresta (plantações ou regeneração natural) e comparando com bancos de dados existentes (GLAD TMF MapBiomas): pouca concordância 🤔

na imagem : preto=floresta estável, vermelho = nosso mapa de regeneração, azul = nosso + 1, verde = nosso + 2/3

indeed, with AI becomming more and more we must expect it being used for good and BAD things

hey Ryan, it was a test to see if it could work for satellite images, as it was not designed with that in mind. Now for applications, i dont know, maybe to clean up some image with clouds for printing purposes, or to create some simulated images for analysis - the sky (& imagination) is the limit !

🛰️🔥This diffusion model app is crazy - it edited the Planet NICFI satellite image changing some areas affected by deforestation, fire & logging to something else - mostly "reforested" them - and it actually looks good 📷

Trecho de Cochrane & Schulze (1998) sobre os incêndios na Amazônia durante o El Niño de 1997! 🌍🔥

Mais de 20 anos depois, o tema segue atual. As lições desses eventos ecoam até hoje - só não sei se são ouvidas. #Amazonia #MudançasClimáticas #Ciência

Today I gave an online talk at #GISFOREST event in Brazil about my research & #CTrees forest monitoring systems that track selective #logging and #roads.

#CTrees new technology and data can help monitor forest management and illegal activities to enhance conservation and sustainable development.

Os dados e tecnologias que estamos gerando com CTrees.org podem ser usados para monitorar o manejo de florestas nativas, bem como atividades ilegais que causam degradação de florestas públicas

Obrigado Ana Dalla Corte e #GISFOREST pelo convite! lignumlatinamerica.com/gis-forest/
