radiometric resolution
[physics] The sensitivity of a sensor to incoming reflectance. Radiometric resolution refers to the number of divisions of bit depth (for example, 255 for 8-bit, 65,536 for 16-bit, and so on) in data collected by a sensor.
The TM sensor provides significant improvements in spatial, spectral, and radiometric resolution compared to the MSS.
The measure of reflected energy is referred to a radiometric resolution. By analyzing energy received by the sensor, information about features can be derived." (Arnoff, p. 63).
Radiometric resolution refers to the number of different intensities of radiation the sensor is able to distinguish.
The radiometric resolution is a function of spectral wavelength and bandwidth (among other things) and operationalized as a digital number (DN).
