DimapV2RadiometricProcessing

class DimapV2RadiometricProcessing(value)

Bases: ListEnum

DIMAP V2 radiometric processing.

See here (Paragraph 2.4) for more information.

classmethod convert_from(to_convert: list | str) → list

Convert from a list or a string to an enum instance

Parameters:

to_convert (list | str) – List or string to convert into an enum instance

Returns:

Converted list

Return type:

list

Example

>>> TsxPolarization.convert_from(["SINGLE", "S", TsxPolarization.QUAD])
[<TsxPolarization.SINGLE: 'S'>, <TsxPolarization.SINGLE: 'S'>, <TsxPolarization.QUAD: 'Q'>]

classmethod from_value(val: Any) → ListEnum

Get the enum class from its value:

Parameters:

val (Any) – Value of the Enum

Returns:

Enum with value

Return type:

ListEnum

Example

>>> TsxPolarization.from_value("Q")
<TsxPolarization.QUAD: 'Q'>

classmethod list_names() → list

Get the name list of this enum:

Example

>>> TsxPolarization.list_values()
["SINGLE", "DUAL", "QUAD", "TWIN"]

classmethod list_values() → list

Get the value list of this enum

Example

>>> TsxPolarization.list_values()
["S", "D", "Q", "T"]

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.

DISPLAY = 'DISPLAY'

In the Display radiometric option, a true colour curve has been applied to the image directly usable for visualisation on screen. The colour curve is the LUT computed by the Reflectance processing. The image true colour is properly retrieved from sensor calibration and correction of systematic effects of the atmosphere.

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.
