etätutkimuksella
Etätutkimus, often translated as remote sensing or distance research, refers to the acquisition of information about an object or phenomenon without making physical contact with it. This is typically achieved through the use of sensors that detect and record electromagnetic radiation reflected or emitted by the object or phenomenon of interest. Data can be gathered from a distance, such as from aircraft or satellites, allowing for the study of large areas or inaccessible locations.
The applications of etätutkimus are vast and span numerous scientific and practical fields. In Earth sciences,
The process generally involves several key steps: data acquisition using sensors, data processing to correct for
