DIMAP V2 radiometric processing.

See here (Paragraph 2.4) for more information.

BASIC = 'BASIC'#

In the BASIC radiometric option, the imagery values are digital numbers (DN) quantifying the energy recorded by the detector corrected relative to the other detectors to avoid non-uniformity noise.

LINEAR_STRETCH = 'LINEAR_STRETCH'#

Relates to the BASIC option at 8-bit depth.

REFLECTANCE = 'REFLECTANCE'#

In the REFLECTANCE radiometric option, the imagery values are corrected from radiometric sensor calibration and systematic effects of the atmosphere (molecular or Rayleigh diffusion and given in reflectance physical unit).

SEAMLESS = 'SEAMLESS'#

Relates to the mosaic option. In this case, the spectral properties cannot be retrieved since the initial images have undergone several radiometric adjustments for aesthetic rendering.
