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 (Union[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.

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.
