How can we embed #innovation into our daily work? 🤔
We create space to experiment with new ideas & technologies without immediate pressure to deliver results. This mindset led to Innovation Summer, making room to explore new ideas. How do you develop new ideas?

We conducted a #GIS training for #PublicHealth with @roteskreuz.bsky.social, @croixrouge.bsky.social, the Colombian Red Cross & @rki.de.

Key lesson: if health professionals and information managers work together, they can translate complex data into high-quality results

What if urban traffic speeds could be estimated using only #opendata?

Our work combines #OpenStreetMap and Street View Imagery to infer #traffic speed classes across a whole city. The focus is on long-term, typical traffic patterns and spatial completeness. Case study: Berlin

We have two new indicators in our assessment tool for residential heating emissions: building construction year & energy carrier🏘️

Let´s test the new features by looking at Kalbach-Riedberg (#Frankfurt). Some areas seems to have no emissions: how is this possible?

The latest #SketchMapTool release integrates #OpenAerialMap, allowing you to add freshly captured drone or openly licensed imagery as a base map with just an image ID. 🗺️

This makes #ParticipatoryMapping even more accessible and efficient in #humanitarian contexts and beyond!

What’s your take on AI-assisted mapping in #OpenStreetMap? 🤖

More map data is now generated automatically, raising questions about transparency and #dataquality. Our research shows AI-created roads are hard to detect once mixed with human edits. How will mapping change?

Dynamic routing for humanitarian logistics

Static #routing fails when roads collapse or flood — slowing relief when every minute matters.
We’re developing dynamic routing that uses real-time, mission-specific data to help responders adapt routes on the fly and avoid delays.

Influence of Meteorological Variables on PM₂.₅ in Temuco

In biomass-heated Temuco, weather turns routine emissions into extreme PM₂.₅ episodes. Using data from 11 stations, the study links meteorology, spatial variability and the need to move away from polluting heating tech.
