## What is ChangeLens Earth?

ChangeLens Earth shows how any place on Earth has changed. Search for a place, pick a Before and an After date, and drag the divider across two free Copernicus Sentinel-2 satellite images to see what's different: a new neighborhood, a flooded river, a harvested field, a retreating glacier.

- Search by place name, address or coordinates, then frame a 1, 3 or 10 km square on the map
- Pick two dates. ChangeLens finds the nearest clear scene over your area and tells you when it had to move the date
- Switch layers: True color, SWIR (vegetation, water, bare or burned ground), Radar from Sentinel-1 that sees through cloud, and Blend
- Pinch to zoom both images together, and step to the previous or next scene
- Save to Photos or share the comparison with the dates, a scale bar, a north arrow and the Copernicus credit line. Full-resolution export also shares the Before and After images as GeoTIFF files for mapping apps

Works on iPhone and iPad. No account, no ads, no analytics and no location request. The app only asks to add images to your photo library when you tap Save to Photos.

Contains modified Copernicus Sentinel data.
