Remote sensing identifies sources of pollution and helps to monitor the spatial localization of this pollution, especially when a particular emergency occurs, as well as to study the concentration of this pollution, its flow and flow velocity and the amount of its dispersion. The space image has the benefits of a comprehensive vision, which helps to study the problem of pollution when covered by a large area and to examine it thoroughly later, and this feature is important in many examples.

The use of remote sensing techniques such as radar, infrared or ultraviolet waves is very helpful in tracking pollution in the ocean environment. Ground observation, as well as aerial photography, may be difficult due to the conditions of vision when photographed, etc...
