  Introduction of remotesensing in coastal management. • Remote sensing techniques have been utilised with various types of sensors and for various applications in environmental purposes since the early 1960s. Weather monitoring and forecasting was one of the first applications of satellite remote sensing, but it was soon apparent that satellites could also be used for detailed mapping of the land surface and for the monitoring of the oceans. The main advantage of satellite remote sensing of the oceans is the fact that it provides large- scale and monitoring of entire basins. At the same time, it can also be used in smaller scales and coastal areas .

  Remote sensing(RS) -Basic • Remote sensing is the obtaining information about an object without making physical contact with the object under study. • In current usage, the term "remote sensing" generally refers to the use of satellite- or aircraft-based sensor technologies to detect the objects on Earth. • Generally remote sensing means sensing of the Earth surface from space by making use of the properties of electromagnetic wave emitted, reflected or diffracted by the sensed object.

  Features of RemoteSensing (RS) • Remote sensing provides a regional view. • Remote sensing provides repetitive looks at the same area. • Remote sensors “see” over a broader portion of the spectrum than the human eye. • Sensors can focus in an specific bandwidth in an image. • Some remote sensors operate in all season, at night, and in bad weather. • Remote sensors often record signals electronically and provide gio-referenced digital data.

  Advantages of RemoteSensing • Advantages: Synoptic view, Temporal • Multi-disciplinary application – Land, ocean, atmosphere • Spatial Resolution: measure of the smallest angular between two object. • Spectral Resolution: number and dimension of specific wavelength to which a sensor is sensitive. • Temporal Resolution : how often a sensor record image of particular area. • Radiometric Resolution : detect diff. Signals.

  CONCLUSIONS.. • The oceanecosystems are threatened by many of causes. Management of these threats is critical to both present and future generations. Innovation in sensor technology and platforms should be encouraged to expand the capabilities of the system or provide information on environmental processes of the coastal area and the open oceans. Additional effort is needed from the oceanographic scientific community of all Mediterranean countries to increase the use of remote sensing systems.
