High-resolution maps of carbon dioxide emissions
Road traffic and residential heating are the two main sources of CO₂ emissions in many cities. HeiGIT´s new emission inventories map these emissions and can simulate the effects of new policies and interventions. We calculated how emissions would change in Heidelberg, Germany, if we introduced a 30 km/h road speed limit and replaced oil and…

OSM Completeness with Overture maps data
Free and open-source map data has become a keystone for research across diverse fields. The extensive coverage of OpenStreetMap (OSM) data allows scientists to conduct independent studies without relying on corporate collaborations or investing heavily in proprietary datasets. However, OSM data coverage completeness varies significantly by location. Moreover, the latest data updates cannot always be…

New paper “Leveraging geospatial data to evaluate women’s employment opportunities in the renewable energy sector”
The renewable energy (RE) sector is a cornerstone of global climate action, yet its workforce remains marked by gender inequality. Women are significantly underrepresented, often relegated to lower-paid, non-technical roles. Traditional analyses of this disparity frequently ignore the spatial dimensions that influence women’s employment opportunities—factors like public transportation access, safety, and neighborhood walkability. Addressing these…

New Paper “Evaluation of accessibility disparities in urban areas during disruptive events based on transit real data”
Studies have long assessed people’s accessibility to amenities through public transportation, typically using General Transit Feed Specification (GTFS) data. GTFS reflects planned transportation schedules, detailing the intended services and routes of transit systems. However, this approach raises an important question: are we missing critical insights by not incorporating real-time information? A recent study led by…

Acting Before the Disaster Happens: QGIS Training and Risk Assessment for Riverine Floods in Pakistan
In the field of humanitarian aid, Anticipatory Action (AA) is emerging as an important strategy to mitigate the impacts of natural disasters. At HeiGIT, we have been actively working with this approach to support local communities in building resilience. Unlike traditional reactive responses, AA aims to initiate predefined actions based on weather forecasts and risk…

Acting Before the Disaster Happens: a Risk Assessment for Cyclones in Madagascar
Anticipatory Action for Disaster Management In the field of humanitarian aid, Anticipatory Action (AA) is emerging as an important strategy to mitigate the impact of hazards. Anticipatory Action is an innovative mechanism that intends to make humanitarian resources available before the disaster happens, based on prior data-driven forecasts and risk assessments. This approach seeks to…
