Seamless Mosaicking

Real areas of interest rarely fit inside one satellite scene, and the scenes that do cover them are rarely cloud-free on the same day. The result, without this service, is a patchwork: visible tile edges, mismatched colour between acquisition dates, and holes where the cloud was. Mosaicking is what turns that into a single image someone can actually put in a report.

The service selects, for every output pixel, the best available observation across the requested period, using cloud and shadow masks, view angle and recency, then harmonises radiometry between contributing scenes and feathers the seams so no tile boundary survives into the product. Compositing rules are chosen per use: most recent cloud-free for currency, median for stability, minimum-cloud for clarity.
