ABSTRACT
School grounds are among the most intensively used everyday environments of children and adolescents, yet their vegetation is rarely evaluated in terms of its capacity to support users’ well-being. This study assesses the structure, quality and functionality of green spaces at ten primary and secondary schools in Olsztyn (north-eastern Poland) using exclusively open geospatial data: Sentinel-2 NDVI summer composites, high-resolution canopy height models, Landsat-derived land surface temperature, OpenStreetMap, the national BDOT10k topographic database and orthophotomaps. Four indicator groups: green area share, tree canopy cover, vegetation structure and neighbourhood greenness, complemented by a checklist of nature-contact elements, were aggregated into a novel School Green Well-Being Potential Index (SGWPI), while land surface temperature served as an independent validation criterion. The results reveal substantial differentiation of school green spaces across the city (SGWPI 32.5–76.8): no school reaches 30% tree canopy cover on its grounds, summer surface temperatures of school grounds span 5.6°C and are governed by the canopy of the 100 m surroundings rather than of the parcels themselves, and primary schools score systematically lower than secondary schools. The proposed remote-sensing workflow is fully reproducible and transferable to other medium-sized cities.
