Fjärrbildsarbete

Fjärrbildsarbete, often translated as remote sensing in English, refers to the process of obtaining information about an object or phenomenon without making physical contact with it. This is typically achieved by using sensors that detect and record electromagnetic radiation, such as light, heat, or radio waves, reflected or emitted by the object.

The data collected through fjärrbildsarbete can then be analyzed to identify, classify, measure, and monitor various features on the Earth's surface, in the atmosphere, or in outer space. Common applications include environmental monitoring, such as tracking deforestation or pollution, agricultural management for crop health assessment, geological surveys for resource exploration, urban planning, and disaster management, such as mapping flood extent or wildfire spread.

Satellites and aircraft are the most common platforms for fjärrbildsarbete, equipped with a range of sensors including cameras, scanners, and radar systems. The type of sensor used depends on the specific application and the characteristics of the radiation being measured. Remote sensing plays a crucial role in providing data for scientific research and decision-making across numerous fields.
