🇪🇺 #EU funding for #FreeSoftware: The Restack programme is a new Horizon Europe initiative for:
🔹 Tech sovereignty & privacy
🔹 Internet resilience
🔹 Reducing environmental impact
🔹 Transparency in the supply chain
For the #FOSS4G community, such large programmes are essential, as they create the legal ⚖️, technical 🛠️ , and potentially financial 💰frameworks from which #geospatial projects can directly or indirectly benefit. Plus @fsfe will provide crucial legal and licensing support.
📚 How to teach modern #GIS? Beyond simple program list!
The interactive graph from 👉 https://www.oss4geo.org/ is a practical resource for #GIS, #Geography, #Geomatics, #DigitalCartography classes:
🗺️ Software Landscape: Click any Desktop GIS to see its underlying libraries and connected tools.
🔄 Data Flows: Trace the data path: Storage (Databases) ➡️ Publishing (Web Servers) ➡️ Visualization (Web-mapping).
🌐 🖱️ An interactive way to teach interoperability and open standards! 🧩 🤝

GeoParquet, an open format for geospatial vector data in #Apache Parquet, combining cloud-native analytics ⚡ with spatial metadata 📄, is becoming increasingly present in geospatial workflows ☁️🌍📊
The #OGC has published guidance for distributing #GeoParquet files, covering compression, spatial indexing & ordering, row group sizing, partitioning, and metadata.
It also includes practical commands for common tools to help generate optimized outputs ⚙️

📡 The #geospatial #ecosystem is increasingly converging around interoperable, cloud-native standards ☁️ 🛰️
The #OGC has officially adopted #openEO as a Community Standard, another step toward API-first, interoperable #EarthObservation workflows 🌍
Together with STAC, COGs, and other cloud-native standards, openEO reflects the broader shift toward a more connected geospatial infrastructure 🔗 🗺️

How is open source funded today? 🤔
More and more, the answer comes from the community 🌍
Crowdfunding for #GeoServer 3.0-RC highlights a clear trend in FOSS4G: users are no longer just consumers, but active contributors to development and maintenance 🔧
Beyond a single project or release, a broader emerging model of collective sustainability is taking shape 🤝

🌍 #EarthDay - a reminder that open source isn't just about code, but about collective action.
From extending hardware life 💻 to satellite monitoring 🛰️ and community mapping of ecosystems🌱, #foss4g tools help us understand and protect our environment. Open data and open tools mean we can all contribute to a more sustainable future.
Beyond the maps 🗺️, #opensource offers endless ways to live sustainably. These practical ideas are still relevant: 👇
