Sentinel-2 Satellite Image Viewer

About this viewer

Pan and zoom a satellite map of Earth, then scrub through years of imagery from the European Space Agency's Sentinel-2 satellites to see how a place has changed. Switch between true colour, a vegetation view and a water view, or ask the guide to fly you somewhere.

• Athabasca Oil Sands, Alberta: One of the largest industrial developments on Earth — mines and tailings ponds have kept expanding across the boreal forest even in the last decade.
• Columbia Icefield Glacier Retreat: The largest icefield in the Rockies is still retreating year after year — even a single decade of Sentinel-2 imagery shows it happening.
• British Columbia Wildfires, 2023: Canada's record 2023 fire season left burn scars visible from space — vegetation index makes them glow.
• The Aral Sea's Vanishing Remnant: The world's most famous shrinking lake had already collapsed by 2015 — what's left keeps drying and briefly refilling with the seasons.
