| Description |
A consolidated Very High Resolution (VHR, sub-meter to ~4 m spatial resolution) optical satellite and aerial orthophoto reference suite used for visual verification, photo-interpretation, geometric quality control, and historical shoreline and hydrographic change validation across Europe and globally, combining the pan-European Copernicus VHR Image Coverages (VHR_IMAGE_2021, acquired during the 2020–2022 vegetation seasons at 2–4 m resolution, and VHR_IMAGE_2024, acquired during the 2023–2025 vegetation seasons at 2 m resolution across EEA-39 countries) coordinated by ESA and the EEA via the Copernicus Data Space Ecosystem ([https://dataspace.copernicus.eu/](https://dataspace.copernicus.eu/)) with global sub-meter (~0.15 m – 1 m) commercial VHR Web Map/Tile Services (OGC WMTS, XYZ, and REST) from Google Maps / Google Earth (including historical imagery timelines spanning ~1984/2000–present), Esri World Imagery (including the Esri Wayback historical archive spanning 2014–present at [https://livingatlas.arcgis.com/wayback/](https://livingatlas.arcgis.com/wayback/)), and Microsoft Bing Maps (multi-date aerial and satellite vintages). |
