How to become ohsome part 13 – An ohsome way to check if OSM is up to date
At long last, welcome to another addition of our How to become ohsome-series! This one is special because we’re discussing a third-party application that uses ohsome API as back-end to accumulate historical OSM data. Although this innovation isn’t directly about our API, it’s close enough (and exciting enough) to merit inclusion and just one more opportunity for…

Understanding spatiotemporal trip purposes of urban micro-mobility from the lens of dockless e-scooter sharing
Over the last two years, we have witnessed the ever-fast growth of micro-mobility services (e.g., e-bikes and e-scooters), which brings both challenges and innovations to the traditional urban transportation systems. For example, they provide an opportunity to better address the “last mile” problem due to their convenience, flexibility and zero emission. As such, it is…

Improving OpenStreetMap missing building detection using few-shot transfer learning in sub- Saharan Africa
OpenStreetMap (OSM) has been intensively used to support humanitarian aid activities, especially in the Global South. Its data availability in the Global South has been greatly improved via recent humanitarian mapping campaigns. However, large rural areas are still incompletely mapped. The timely provision of map data is often essential for the work of humanitarian actors…
