Air pollution caused by fine particulate matter (PM₂.₅) is a major public health concern worldwide. Prolonged exposure to PM₂.₅ is associated with higher rates of cardiovascular and respiratory diseases, which…
Ein neuer globaler Datensatz des HeiGIT (Heidelberg Institute for Geoinformation Technology) ermöglicht es weltweit zwischen befestigten und unbefestigten Straßen mit bisher unerreichter Konsistenz zu unterscheiden. Die aus hochauflösenden Satellitenbildern abgeleiteten Daten…
This study investigates sugarcane farmland abandonment in Rio de Janeiro State, Brazil, employing spatial regression techniques to identify the biophysical and accessibility factors that determine where abandonment occurs at the…
Das Silver Ways Projekt hat das Ziel, älteren Menschen die Fortbewegung in Städten zu erleichtern, indem ein auf ihre Bedürfnisse zugeschnittenes Routing-System geschaffen wird. Um dieses System auf reale Erfahrungen…
This study develops a framework integrating satellite observations with spatial proxy data to produce high-resolution urban carbon emission maps. The method is applied to Urumqi, China, demonstrating accurate and timely…
Using Heidelberg as a case study, researchers modeled time-dependent solar exposure for the entire pedestrian network by combining high-resolution DEM/DSM building and vegetation data with OpenStreetMap road data. Adapting to…
This study evaluates the applicability of macro-scale energy poverty indices in an urban context, using Santiago de Chile as a case study. Energy poverty (EP), understood as the inability of…
Walking supports healthy aging, but older adults often prioritize safety and comfort over speed. This study uses a scoping review to examine these preferences and guide age-inclusive routing systems. Walking…
Das Projekt Silver Ways möchte Fußwege in Mannheim seniorengerecht gestalten. Eine laufende Umfrage sammelt Erfahrungen älterer Menschen. Ziel ist eine bessere Alltagsmobilität. Ihre Teilnahme ist wichtig: machen Sie jetzt mit!…
A recent study has demonstrated a novel approach to the large-scale monitoring of road traffic. Rather than relying on radar or mobile sensors, the team used PlanetScope’s Super Dove satellite…
Searching for early warning systems during the COVID-19 pandemic, the researchers explored how digital data sources such as geo-social media (e.g. posts on platforms like X, formerly Twitter, that include…
A study published on ScienceDirect evaluates the capability of LLMs to mimic human-like decision-making patterns in parking scenarios. Through experiments, researchers reproduce realistic trade-offs between cost, distance, and availability, while…
This study introduces the isocalor approach to assess how solar exposure and heat stress impact pedestrian access to essential services in Heidelberg, using OpenStreetMap data and a customized openrouteservice routing…
This study examines the resilience of urban infrastructure, with a focus on road network connectivity and redundancy in the face of extreme weather events. Using OpenStreetMap (OSM) data and the…
This study, published at African Transport Studies, investigates the impact of school sessions on traffic congestion in Nairobi, highlighting how children’s mobility needs are often overlooked in transport planning. The…
Since 2016, corporate involvement in OpenStreetMap (OSM) has grown significantly, with major contributors such as Apple, Microsoft, Meta, and Amazon making substantial edits to the map on a global scale….
To improve vector control strategies, Dr. Steffen Knoblauch (PostDoc at GIScience and HeiGIT) has developed detailed maps showing where Aedes aegyti is most likely to thrive. Using a holistic approach,…
From January to March 2025, Dr. Steffen Knoblauch undertook a post-doctoral research visit at the African Institute of Mathematical Sciences (AIMS) in Cape Town, South Africa. His research focused on…
The paper addresses the global shortage of detailed road surface data by leveraging street-view imagery from Mapillary and advanced deep learning techniques. Traditional datasets like OpenStreetMap (OSM) often lack comprehensive…
