The sensing and recording ability of the sensor in different wavelength of electromagnetic radiation is known as :
Answer: D
The ability is spectral resolution.
Spectral resolution describes how many bands of the electromagnetic spectrum a sensor records and how narrow they are. A multispectral sensor records a few broad bands; a hyperspectral sensor records hundreds of narrow ones.
The other three are different properties. Spatial resolution is the size of the smallest ground area a pixel represents. Radiometric resolution is the sensitivity to differences in brightness, expressed as the number of bits per pixel. Temporal resolution is how often the sensor revisits the same place.
