Satellite maps are images of Earth taken by human-made satellites orbiting our planet. When these images are connected, they show a bird’s eye view of locations, landscapes, and properties of all sizes. The uses for satellite maps go far beyond casual use. They are a powerful resource for navigation, city planning, environmental monitoring, and disaster response. By providing an alternative perspective, satellite maps allow us to visit the places we care about in ways we could never before.
