Távérzékeléses

Távérzékeléses is a Hungarian term that translates to "remote sensing" in English. It refers to the process of acquiring 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 reflected or emitted from the target. The most common form of remote sensing involves the use of satellites or aircraft equipped with specialized cameras and instruments. These sensors capture data across various parts of the electromagnetic spectrum, including visible light, infrared, and microwave frequencies.

The data collected through remote sensing can be analyzed to derive a wide range of information. In environmental monitoring, it is used to track deforestation, assess crop health, monitor water quality, and study climate change patterns. For geological surveys, remote sensing helps in identifying mineral deposits and understanding landforms. It also plays a crucial role in urban planning, disaster management, and military reconnaissance. Different types of remote sensing exist, including passive remote sensing, which detects naturally occurring radiation like sunlight, and active remote sensing, which emits its own energy source, such as radar, and then measures the reflected signal. The interpretation of this remotely sensed data often involves sophisticated image processing and analysis techniques.
