New Paper in Nature “OSMlanduse a dataset of European Union land use at 10 m resolution derived from OpenStreetMap and Sentinel-2”
The paper, published in Nature Scientific Data, presents the first high-resolution (10m or finer) land use map of the European Union derived from a large-scale fusion of OpenStreetMap (OSM) and Copernicus Sentinel-2 data. Leveraging citizen-generated data and remote sensing, the authors demonstrate a scalable and globally applicable methodology to fill thematic and spatial gaps in…

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…
