Discussion
The dimension and number of specific wavelength intervals in the electromagnetic spectrum to which a sensor is sensitive are known as the ................. resolution.
Answer: A
It is the spectral resolution.
Spectral resolution describes the number and width of the wavelength bands a sensor records. A multispectral sensor has a few broad bands, and a hyperspectral sensor hundreds of narrow ones, giving finer spectral resolution.
Spatial resolution is the size of the smallest ground area a pixel represents. Temporal resolution is how often the sensor revisits the same place. Radiometric resolution is the sensor's sensitivity to differences in signal strength, the number of grey levels it can record.
