#spectral resolution

Spatial Resolution

The spatial Resolution proportionate the size of the smallest object that is available to be seen by the sensor. In this case, the size is defined and is formed in pixels. This is measured by the Instantaneous Field of View (IFOW), which is the angular section measured in radians, observed in a point determined by the sensor. It uses the terrain distance to correspond in the angle and depends on the view of the angle. The pixel is different (Picture element): spatial is done by the frequency made. The terrain has better coverage when both signals are recognized. The information is influenced by (digital value) offered pixels.

Spectral Resolution

The spectral resolution is the number and the width of the spectral bands that the sensors can discriminate. It can also define the capacity of the sensor to discriminate the radiance detected in distinct longitudes of the spectral wave. The number of bands comes predetermined on what the sensor can capture and the width of the spectral. It is convenient to have a high number of bands and stretch bands, which allows a finer discrimination. It is a determined sensor, the number of bands posed and width depend on the application it has been given.

Radiometric Resolution

The radiometric resolution is the sensitivity of the sensor, the capacity to detect the variations in spectral radiance that are received.
