REM (Remote Sensing)

Remote sensing (REM) is the technique of gathering information about an object or area from a distance, often using satellites or aircraft. It captures data through sensors that detect reflected or emitted energy, such as light. This information helps in a variety of fields, including environmental monitoring, agriculture, urban planning, and disaster management. By analyzing images and data, scientists can track changes, assess natural resources, and improve decision-making, thus enhancing our understanding of the Earth’s landscapes and systems without the need for direct contact.
