New paper “Corporate Mapping in OpenStreetMap – shifting trends in global evolution and small-scale effects”
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. These efforts have often focused on filling gaps in high- and medium-income countries, contributing to the overall growth of OSM data. However, this increasing corporate…

New Paper in Lancet Planetary Health “Urban Aedes aegypti suitability indicators”
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, his work leverages geospatial big data – including openly available satellite and street view imagery as well as climate data – to identify common breeding…

use case: openrouteservice for AI-Enhanced Building Data and Demographic Prediction
This research shows how spatial indicators from openrouteservice (ORS) can support building-level demographic predictions using machine learning. The study combines ORS APIs, building attributes, and POI data to estimate population and age characteristics in German cities, offering insights into the relationship between urban accessibility and demographic patterns. In today’s data-driven world, understanding cities at a…

New Paper: “Paved or unpaved? A Deep Learning derived Road Surface Global Dataset from Mapillary Street-View Imagery”
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 road surface attributes—with only about 30–40% coverage—hindering applications such as travel time estimation, disaster response routing, urban planning, and environmental assessments. To fill this gap,…

Harnessing UAV Technology to Support Municipal Solid Waste Management
The full article was originally published on geoawesome. The management of Municipal Solid Waste (MSW) represents a significant challenge, particularly in regions lacking adequate waste management infrastructure. In Africa, several regions are identified as critical hotspots for waste mismanagement. In 2012, only 55% of MSW was collected across Africa, with a mere 4% being recycled,…

First release of ohsome-planet: OSM history data in GeoParquet format
We’re excited to share the release of the ohsome-planet – a new software library on GitHub, marking a significant step toward the development of ohsome 2.0. This tool is designed to facilitate the transformation of raw OpenStreetMap (OSM) history data into the GeoParquet format, making it more accessible and efficient for spatial data analysis. What…

New Paper “GeoDEN: A Visual Exploration Tool for Analyzing the Geographic Spread of Dengue Serotypes”
With the increasing availability of global disease datasets, Visual Analytics (VA) has emerged as a valuable tool in spatial epidemiology, particularly for studying serotype interactions in diseases like dengue. Dengue, caused by four serotypes (DENV1-DENV4), poses a significant global health threat exacerbated by urbanization and climate change. Traditional approaches rely on static mapping or animation…

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…
