|
Remote Sensing |
Is the science and art of acquiring information about material objects from measurements made at a distance(on board a platform) without coming into physical contact with the material of interest. |
|
|
Electromagnetic Radiation. |
Is the Energy transmitted through space in the form electric and magnetic waves |
|
|
Pixel |
Is the smallest resolved detail to which a unique radiance value is attached. The smaller the pixel, the higher the resolution. |
|
|
The IFOV |
Is defined as the angular subtense at a given instant of limiting detector aperture |
|
|
Sunsynchronous |
An earth satellite orbit in which the orbital plane is near-polar and the satellite passes over all places on earth having the same latitude as the sun time. |
|
|
Spectral Resolution |
A measure of the wavelengths of light being sensed and the sensor bandwidths and the sensitivity of the sensor to distinguish between gray levels. |
|
|
Spatial Resolution |
The ability of a sensor to see the smallest possible objects as separate from its surroundings. |
|
|
Temporal Resolution |
Is a measure of the time required to image the earth and to repeat over the same scene days or weeks later for change detection. |
|
|
Blackbody |
Matter that is capable of absorbing and re-emitting all EM energy that it receives. Blackbody = eminivity + absorptivity = 1 |
|
|
Equations under EM. E |
C= f*Lumdar Q= h*f |
|
|
Passive Systems |
Employ natural sources of energy |
|
|
Active systems |
Have their own source of energy. |
