Last year, we published our initial roadmap toward ohsome 2.0, outlining a transition from our established OpenStreetMap History Database (OSHDB) toward a Postgres backend enhanced by PostGIS and Citus. This structural update shifts the foc…
What ohsome-planet does The ohsome-planet tool can be used to transform OSM (history) PBF files into Parquet format with native GEO support, to turn an OSM changeset file (osm.bz2) into a PostgreSQL database table, and to keep both datasets…
Following the catastrophic earthquakes in Venezuela on June 24, 2026, humanitarian organizations face a compromised operational landscape. With over 3,600 confirmed fatalities and tens of thousands missing, the immediate priority is deliver…
Scaling Up Mapping with Volunteers and Computer Vision In many regions of the world, road and urban infrastructure is still under-mapped, which makes it particularly difficult for policy makers and local administrations as well as for human…
For well over a decade, our team has been transferring research to our ecosystems of mobility tools. These services are stable and maintained. Developing a dedicated public transit routing engine has long been a major milestone on our roadm…
The Colombian Red Cross’s Disaster Risk Management (DRM) team works to mitigate the impact of emergencies and enhance community resilience throughout the country. Coordinating actions at both national and regional levels, the team focuses o…
From assessing CO2 emissions from residential heating to urban active mobility infrastructure, the Climate Action Navigator helps identify where targeted action is most urgently needed to counteract climate change. The newly added Rooftop S…
Von der Ermittlung der CO₂-Emissionen aus der Wohnraumbeheizung bis hin zur städtischen Infrastruktur für aktive Mobilität hilft der Climate Action Navigator dabei, zu ermitteln, wo gezielte Maßnahmen am dringendsten erforderlich sind, um d…
This study examines Berlin, Germany, where the authors modeled street-level traffic speeds at four key times: nighttime, morning peak, flat peak, and evening peak. They built the selected road network using OpenStreetMap and represented it
