Remote sensing is the science of obtaining information without physically being there.
With this in mind, the 3 most common methods to capture data is by airplane, satellite and drones.
For example, how can we understand the current weather and even predict the future weather for the whole globe?
Ultimately, weather forecasting satellites capture cloud cover and their movements so meteorologists can better predict weather patterns across the globe. But this is just the tip of the iceberg.
