The FOSS4G Observatory (ex-OSS4gEO), is a 2- year activity funded by ESA through the permanently open call Future EO-1: EO Science for Society and carried out by Terrasigna. It is part of a wider ESA initiative to actively support and contribute to the open source community and it is intended as a seed action to better understand, represent and harvest the geospatial open source ecosystem.

It is admirable to observ how the #FOSS way value&the 💪 of building 💻 solutions following the #FOSS principles is gaining momentum within 🌍 organisations. In 2025, 🇺🇳 UN officially 🚀 the Open Source United, a UN-wide initiative to coordinate and scale📈 open source efforts across its entire system. This week, the United Portal 🚀 👉 https://opensource.un.org/en. When it comes to geospatial, we can only encourage 🇺🇳 to blend in the already mature #FOSS4G ecosystem as can be easily seen in the @OSS4gEO

#FOSS is expensive 💸 ... when you don't do it right. According to one of the latest reports📝 of the @linuxfoundation the #ROI for companies that contribute back to the #FOSS projects they depend on is between 2-5X, while for the ones passively consuming (and forking privately) it actually turns into technical debt on the medium-long term. Check out the report and the data 📚 it relies on 👉 https://www.linuxfoundation.org/research/contribution-roi?hsLang=en

The FOSS4G conferences are among the most awaited geospatial events of the year. Everything, from moving from ⛩️ to 🏛️ , to the✨ variety that each LOC instills in their conference, to the excitement of meeting geospatial gurus, make people 🌍 flock to these FOSS4Gs. But maybe one of the coolest is the opportunity to have your say regarding the program! Respecting total anonymity of the voter and of the authors, one can vote what she would like to see. 🗳️ Choose the @foss4geurope workshops! 👇

Since @CopernicusEU was known as #GMES, there was a❓in the back of everyones' 🧠: will we have the capacity to fully benefit from the Sentinels? A lot has happened since the S-1A🚀 and 2 decades later, the direction of full exploitation of Copernicus data is driven by #FOSS 💪
@developmentseed, EOX& thriveGEO, supported by @esa launched the #EOPF #Sentinel @zarr Explorer, an ecosystem supporting cloud-native exploitation and visualisation of Earth Observation data! 📖 👉 https://developmentseed.org/blog/2026-02-13-eopf-explorer-launch/
