Answer;
-Remote sensing
Step-by-step explanation;
-Remote sensing involves obtaining information about objects or areas from a distance, typically from aircraft or satellites.
-Remote sensors collect data by detecting the energy that is reflected from Earth. These sensors can be on satellites or mounted on aircraft.Remote sensing has a wide range of applications, such as coastal applications (monitoring shoreline changes), ocean applications to monitor ocean circulation and current systems, and hazard assessments among other applications.
