New paper “STVAE: Skip connection driven two-stream property Fusion Variational AutoEncoder for cross-region wastewater treatment plant semantic segmentation”
Wastewater treatment plants (WWTPs) play a crucial role in maintaining ecological balance and public health and are essential for advancing social sustainable development goals. However, the diverse architectural styles, scales, and environmental contexts of WWTPs—shaped by climate, topography, and regional economic conditions—pose significant challenges for generalizing segmentation algorithms. To address this, integrating knowledge from different…

OSM Completeness with Overture maps data
Free and open-source map data has become a keystone for research across diverse fields. The extensive coverage of OpenStreetMap (OSM) data allows scientists to conduct independent studies without relying on corporate collaborations or investing heavily in proprietary datasets. However, OSM data coverage completeness varies significantly by location. Moreover, the latest data updates cannot always be…

Accurate road surface data for transportation, safety, and economic development
Researchers at HeiGIT (Heidelberg Institute for Geoinformation Technology) have publicly released a first of its kind planet-scale dataset on road surface type (paved or unpaved) using state-of-the-art GeoAI methods based on street-view imagery from Mapillary, in order to support humanitarian response, urban planning and progress towards the Sustainable Development Goals. Road surface information plays an essential…

Analysis of OSM building data completeness using new data
With thousands of people mapping in OSM every day, missing building data in urban centers is steadily decreasing. Since OSM is a widely used source for projects researching urban phenomena around the world, a good data quality and an even distribution are important factors. If a spatial bias is present but not accounted for, researchers…

The EU-Project “Gitterzellendatenbank”: Determining Reachability Made Easy With Openrouteservice (ORS)
Free open geodata are of increasing importance. They are used in research or case studies and can lead to important insights on social, economic or environmental topics. A problem that often occurs while working with various kinds of geodata is that they cannot be used together because of differing spatial reference units. The Federal Agency…
