Remote Sensing
Definition
The acquisition of data about Earth's surface from a satellite orbiting Earth or from other long-distance methods.
Analogy
Imagine remote sensing as if it were a bird flying high above us. From its vantage point, it can see much more than we can from ground level - things like weather patterns, vegetation growth, even changes in river courses!
