How to read it
The left image is a Landsat scene from 1990-09-22, 30 metres per pixel. The right is a Sentinel-2 scene from 2026-10-21, 10 metres per pixel. Both are true colour: what a person would see from orbit. Sand is pale, water dark, vegetation green, cities grey.
In the satellite tool you can step through every year in between, switch to plant health, water, burn or surface temperature, draw an area to measure what changed, and watch the place for new passes.
