Each image in Aurora is tagged with a processing version that reflect the algorithms used to generate the final output. This version indicates the exact set of radiometric, geometric, atmospheric, and packaging algorithms used to generate the image.
The Product Versions section provides a public reference for all released processing versions and the improvements introduced in each.
