STAC harvest · raster Tiles

A source COG, kept in view.

ESA WorldCover STAC → preserved source metadata and a byte-identical official COG mirror → Tellurion STAC/Features/raster Tiles. The map is the live proof: Tellurion reads that COG and composes PNG tiles for this browser.

Render may need a short cold start before PNG tiles appear.

Live raster proof

WorldCover over Rome

One MapLibre raster source requests Tellurion PNG tiles directly from the harvested WorldCover source.

The map is waiting for the public tile service. If it remains unavailable, inspect the independent resource checks below and retry after Render wakes.
