Remote Sensing

Definition

Remote sensing is the process of obtaining information about an object or area from a distance, typically using satellite or aerial imagery. This technology allows for the collection and analysis of data regarding environmental conditions, wave characteristics, and other geophysical phenomena without making direct contact with the subject being studied. It plays a crucial role in monitoring changes in landscapes and ecosystems, making it invaluable for environmental management and understanding oceanic behavior.
