New Paper “An explainable GeoAI approach for the multimodal analysis of urban human dynamics: a case study for the COVID-19 pandemic in Rio de Janeiro”
The COVID-19 pandemic highlighted the importance of understanding human behavior in cities to develop effective public health interventions. Crowd-sourced geospatial data available online can therefore serve as a valuable resource for analyzing such dynamics with Geospatial Artificial Intelligence (GeoAI). However, previous research often struggles with the complexity and heterogeneity of such data, and faces challenges…

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…

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…
