Remote sensing is to collect the information from the object without making direct physical contact with the object. A simple definition is that remote sensing in our study field is observation for the earth surface or atmosphere by electromagnetic scattering or radiation, using instruments carried on some platforms (plane, satellite or ground base).
Remote sensing can provide images of broad view and observation in a very short time, and is widely used in the area of atmosphere, ocean, land surface, military reconnaissance, and so on. It can provide abundant information with low resources cost, which makes it a commonly way to detect and classify the objects on Earth. Remote sensing makes it possible to collect data of dangerous and desolation area. It provides effective detection in area such as the Arctic and Antarctic regions, the Amazon region and area in desert and ocean. In addition, remote sensing can also be used in the field of Land, ocean, atmosphere and outer space. Remote sensing makes the data collection for areas and objects more easily and convenient for people than before.
The objective of the program is to make students understand the fundamental physics of remote sensing to direct the remote sensing practice and application, the principles and methods of the process of the electromagnetic radiation transfer and remote sensing; to master the imaging mechanism, data characteristics and correlative technologies in applications in wavelengths of VNIR, TIR and microwave; to grasp the principles and methods of geometrical correction and radiation calibration for remote sensing data; and to acquire the knowledge for remote sensing image understanding and exploitation. Students are expected to be able to analyze the phenomena existing in the practice of remote sensing using the corresponding knowledge and methods learned from this study.
