Unlock Earth's Secrets

Access massive collections of satellite imagery with ArcGIS

Earth observation satellite missions like Landsat and Sentinel-2 allow people to see the earth in a unique way. These satellites have taken millions of images across our globe to reveal Earth's secrets, from volcanic activity to urban sprawl. The images they continue to gather provide an increasingly powerful tool for mapping and visualizing the world.

Explore the invisible world

Many Earth observation satellites see things on the electromagnetic spectrum, including what's invisible to the human eye.

Different spectral bands yield insight about our continually changing Earth. Scientists and GIS analysts use these satellites to keep an eye on places like the Cambridge Gulf in Australia, where mangroves are threatened by cyclones and industrialization.

Travel through time

Earth observation satellites repeatedly gather images of every location on the planet so we can see how places change over time. For example, Sentinel-2 satellites fly over locations at least every 5 days, and Landsat satellites fly over once every 16 days.

Farmers and analysts can measure how crops are developing in places like Bakersfield, California. Different crops appear in different colors at specific times in their growth cycle. Variations indicate stress due to lack of water or fertilizer. This analysis helps not only farmers but also analysts who predict market prices based on supply.
