True color conversion

The process applies color curve correction and bit conversion to 16-bit encoded RGB bands in Pléiades, Pléiades Neo, or SPOT imagery. The result is a 8-bit true color GeoTIFF file.

True color correction can be used as a preprocessing step before applying analytics processes.

The process is optimized for input data items that have a look-up table (LUT) file. It uses the LUT file to map RGB pixel values to an accurate true color representation.

If the LUT file is unavailable, the process defaults to linear stretching and clipping. For improved color fidelity, use input data items that have LUT files.

Input data items must be added to storage in 2023 or later.

Use the true-color-conversion name ID for the processing API.
