El primer experimento a escala urbana de crowdmapping salio de Kibera. Ushahidi se llamaba. Hoy parece el precambrico de internet.

A ciência brasileira está mostrando como se faz o combate às espécies exóticas invasoras na era digital. Pesquisadores da ESALQ/USP, em Piracicaba, criaram um projeto pioneiro que cruza sensoriamento remoto, Inteligência Artificial e ciência cidadã para rastrear e erradicar a Leucena (Leucaena leucocephala), uma das plantas mais destrutivas para a nossa biodiversidade. ​☠️ O "Veneno" Silencioso da Leucena ​Não se deixe enganar pelas flores delicadas. A Leucena é classificada pela IUCN como uma das 100 piores espécies invasoras do mundo, e os motivos são devastadores. Além de crescer até 3 metros em um único ano e produzir uma quantidade absurda de sementes, ela possui um efeito alelopático. Na prática, a árvore libera substâncias químicas no solo que funcionam como um herbicida natural contra outras plantas, impedindo a germinação e regenerando da nossa flora nativa ao seu redor. ​🤖 LiDAR e Redes Neurais na Floresta ​Na engenharia florestal moderna, para controlar uma invasão em larga escala, precisamos enxergar o inimigo de cima. O projeto utiliza drones para captar imagens multiespectrais de altíssima resolução (25 cm) e tecnologia LiDAR (pulsos de laser que criam modelos 3D do relevo e da copa). Com esses dados, as Redes Neurais Convolucionais (Deep Learning) fundem as imagens ópticas com a modelagem 3D para segmentar e classificar automaticamente onde a Leucena está dominando a paisagem, gerando mapas precisos para as prefeituras agirem. ​🤝 Ciência Cidadã: A Máquina Precisa de Você ​A grande sacada do projeto estruturado por Matheus Siqueira Barros e pelo Prof. Dr. Matheus Pinheiro Ferreira é que a Inteligência Artificial precisa de humanos para "aprender" a reconhecer a árvore. Através da plataforma leucaena.earth, qualquer voluntário pode participar do crowdmapping, desenhando máscaras digitais sobre as copas das árvores nas imagens de satélite e treinando os algoritmos que vão proteger as nossas matas.

📣@UNDP Istanbul International Center for Private Sector in Development is looking for 100 Online Volunteers to support post-earthquake recovery efforts in Myanmar through crowdmapping and data analysis. 🔹 Duration: 6 weeks 🔹 Commitment: 11–15 hours/week 🔹 Start: As soon as possible 🔹 Location: Virtual 📍Volunteers from Myanmar are strongly encouraged to apply. 👉Apply: bit.ly/4czcYPh

4/ **Crowdsourced Risk Mapping 🗺️🖊️** Innovative mapping platforms allow residents to share knowledge about local hazards and vulnerabilities, creating dynamic, crowd-sourced risk maps that inform planning and response strategies! #CrowdMapping #DisasterRisk

New paper alert! Disparity, Instability, and Power in the Crowdmapping Ecosystem by @re_sieber and me for the Journal of Community Informatics.

#30DayMapChallenge Day 11: Students in Aklavik (Canada) helped capture drone images of their village in the #Arctic. Berlin students then identified power poles with our #crowdmapping app (mapswipe.org), as part of the undercovereisagenten.org project on #permafrost.

Exciting news! I'm glad to announce that my colleague #Yohannes and I will be co-presenting @sotmafrica about our successful project on #CrowdMapping for Food Security in #Ethiopia. Join us to learn how we made a positive impact through mapping. Don't miss out! #SotMAfrica

@UNESCO_Addis looking forward to the monitoring framework on media violations using #AI and #Crowdmapping with special focus on female journalists in Africa @RBissoonauth

I knew this, but seeing it happen is crazy. Governments have no idea that victims don’t report violence because of victim blaming. This just highlights the importance of @TheSafecityApp work on crowdmapping violence. It gives the community a chance to speak up!

#stormBabet #Flooding in #Scotland #Wale reveals the seriousness of today's event. #UnitedKingdom Spot the submerged areas & roads, share descriptions of impacts with neighbors and the world with the free crowdmapping app @signalert

Well done! 👏👏👏 Last year Grand Challenges awarded funding to Crowdmapping for Food Security in Ethiopia as part of our four special initiative themes!

The #Crowdmapping for #foodsecurity in #OMO zone #event was a huge success! @osmethiopia mappers mapped #Nyangatom & #Hammer districts, @CharlesChiluf12 presented on validating tasks & best practices. Congratulations to z data cleaning team, & thanks to all involved! #mapathon

👏👏#GoodJob #Team👏👏 The @osmethiopia #dataanalysis team #conducted a data cleaning process for the "#Crowdmapping for #foodsecurity in #OMO zone" project, to ensure consistency and accuracy for the data.#datascience #foodsecurity #crowdmapping

Exciting news! @osmethiopia‘s "#Crowdmapping for #FoodSecurity in #OMO zone" event showcased the engagement and co-design approach used in the project. The mapping technique involved GPS and satellite imagery-based functionalities integrated into z app.#crowdmapping #innovation

Collective Intelligence 🧠 unlocks incredible potential when people collaborate using technology & data. Methods like crowdmapping harness local knowledge to tackle disasters & climate change.🌏They empower communities to ✒️shape plans & decisions, making a difference together!
