New Jupyter Notebook: Analysis of Access to Health Care using openrouteservice Isochrones API
What is the idea behind the Notebook? In the case of an emergency (e.g. floods, earthquakes, political crisis) it is important to know where the health facilities are located. Furthermore, it is important to identify which cities/districts have a reduced or no access at all to health facilities before an emergency. Many countries still posses…

Recent changes to OpenStreetMap healthcare infrastructure in India
India accounts for nearly 18% of the worlds population. The country is also one of the main carrier of the worlds disease burden. Despite the general increase in life expectancy and decreasing mortality due to communicable diseases and malnutrition in recent years, the numbers of non-communicable diseases are rising substantially. Cardiovascular diseases such as diabetes and…

Mapping physical access to health care for older adults in sub-Saharan Africa and implications for the COVID-19 response: a cross-sectional analysis
New paper published on healthcare access in Sub-Saharan Africa It is almost a year since SARS-CoV-2 first emerged in China. The virus spread all over the world. Countries south of the Sahara did not receive much attention. Although outbreaks here have a strong risk potential due to existing crises. In our new published paper we…

Exploring OSM for healthcare access analysis in Sub-Saharan Africa
[tl;dr] Using hospital locations and the ORS Isochrone service, we have created a method for comparing physical access to healthcare in Sub-Saharan Africa. Hospital locations were derived from OpenStreetMap and compared against another free available dataset. Results indicate strong similarity in both hospital datasets, however the uncertainty of our method requires further evaluation. Figure 1…

Analysing OSM Completeness of health facilities in Sub-Sahara Africa in ohsomeHeX
A new map in ohsomeHeX provides an overview of areas in Sub-Sahara Africa where information on health facilities is still missing in OpenStreetMap (OSM). The completeness of OSM is measured by comparing to a reference dataset on public health facilities in Sub-Sahara Africa, which was developed by Maina et al. 2019. Especially in these days,…

Green spaces in cities promote well-being and mental health — ‘Nature’ Neuroscience study published with participation of GIScience researchers at Heidelberg University
INTERDISCIPLINARY NATURE STUDY SHOWS THAT INNER TOWN GREEN DIRECTLY INFLUENCES ON CITY RESIDENTS Inner city green areas such as lawns, flowerbeds, trees or parks can directly improve the well-being of city dwellers. These are the findings of a recent study conducted by scientists from GIScience Research Group at Heidelberg University and the Heidelberg Institute for…

Introducing Healthy Routing preferring Green Areas with OpenRouteService
Research in psychology and public health shows that there are environmental factors that cause an area to impose more or less stress to a person. One example is that being surrounded by natural green areas (meadows, parks, trees and forests etc. or also blue water areas) has a relaxing influence to the mood of a…

New Paper in Scientific Reports “Modeling Intraday Aedes-human exposure dynamics enhances dengue risk prediction”
Scientific Reports publishes a paper by Steffen Knoblauch et al. that underscores the critical importance of integrating vector ecology and human behavior into advanced disease modeling frameworks. The increasing availability of human movement data presents significant potential for tackling global public health challenges, especially in the context of infectious diseases. This is particularly important for…

New Paper “AI-Generated Buildings in OpenStreetMap: Frequency of Use and Differences from Non-AI-Generated Buildings”
The concept of a “Digital Earth” has long envisioned a future where technological advancements enable the large-scale collection and visualization of spatial and environmental data. Today, open data sources such as OpenStreetMap (OSM) provide crucial spatial information for diverse applications, including urban planning, disaster management, and public health. However, many regions remain insufficiently mapped, particularly…

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 “Geosocial Media’s Early Warning Capabilities Across US County-Level Political Clusters: Observational Study”
The novel coronavirus disease (COVID-19) generated significant health concerns worldwide, leading policymakers and health care experts to implement nonpharmaceutical public health interventions to mitigate the spread of the virus. While these interventions played a crucial role in controlling transmission, they also resulted in substantial economic and societal costs, necessitating strategic deployment, particularly during periods of…
