Worldwide Basemap

A seamless, current, cloud-free global backdrop, recomposited continuously — available at 10 m source, 5 m physics-based Derived Resolution (no ML artefacts), and 2.5 m Super-Resolution.

Wide-area work needs a seamless, current, cloud-free backdrop — not a patchwork of scenes from different dates and seasons. ETD's worldwide basemap composites Sentinel-2 and recomposites continuously as new cloud-free pixels arrive, in three forms: the 10 m source, a 5 m Derived Resolution produced purely by physics (no machine learning, so no hallucinated artefacts — the clean choice for reference and measurement), and a 2.5 m Super-Resolution for maximum detail. Two layers run in parallel at each: a latest-usable mosaic that favours minimal cloud and haze for a clean reference, and a latest-change mosaic that always shows the freshest pixel for monitoring fast-moving situations. It is the foundation for the map tile server, AOI selection, and any application needing a consistent global canvas.
