Aerial
20+ countries, down to 5cm
For the highest-detail base imagery, nothing beats aircraft. Many governments fly national aerial surveys at 5–25cm and publish the orthoimagery — but it is scattered across dozens of incompatible national portals, formats, and projections.
EarthToDate ingests and harmonises aerial coverage from 20+ countries into one consistent layer, ranging from 20cm down to 1cm per pixel, with some national sources refreshing continuously.
Where available, aerial provides the ground-truth detail layer beneath ETD's satellite products — for verification, for the finest-scale inspection, and for blending high detail with frequent satellite revisit.
