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…

New Paper “Crime-associated inequality in geographical access to education: Insights from the municipality of Rio de Janeiro”
To what extent does crime potentially inhibit geographical access to schools, measured by cumulative average travel time? Education is recognized globally as a fundamental human right and essential for promoting equality,eradicating poverty, reducing crime, and supporting sustainable development. Despite global progress, full educational access remains a challenge, particularly in highly criminal areas. The paper uses…
