Understanding spatiotemporal trip purposes of urban micro-mobility from the lens of dockless e-scooter sharing
Over the last two years, we have witnessed the ever-fast growth of micro-mobility services (e.g., e-bikes and e-scooters), which brings both challenges and innovations to the traditional urban transportation systems. For example, they provide an opportunity to better address the … Read More
Spatial Data for Society – Leading HeiGIT to the Future
Underpasses, stairs, and high curbsides are a challenge for people with impaired mobility, but these can be circumnavigated using a customized route planner for increasing mobility by calculating routes with the least amount of obstacles. This example emphasizes how geoinformation technology and … Read More
Automatic mapping of national surface water with OpenStreetMap and Sentinel-2 MSI data using deep learning
Large-scale mapping activities can benefit from the vastly increasing availability of earth observation (EO) data, especially when combined with volunteered geographical information (VGI) using machine learning (ML). High-resolution maps of inland surface water bodies are important for water supply and … Read More
A Web App to generate and disseminate knowledge on urban green space qualities and their accessibility
