remote sensing
Distance-based detection
Remote sensing is gathering information about something from a distance, typically using satellites or aircraft to collect data about Earth's surface.
The technology detects electromagnetic radiation—visible light, infrared, radar—to map terrain, monitor weather, track deforestation, or assess crop health.
Remote sensing revealed the extent of the oil spill.
The term extends to any measurement taken without physical contact.
