Cartesian Product Format

The data portion of Cartesian product files is not compressed and consists of an array.

The first byte contains the lower left corner of the image, the second contains the pixels to the right of that, and so on from the bottom of the window to the top. For 3-D products, the lowest 2-D image comes first.

In some cases a product header extension is added to the Cartesian products, and may store multiple data types. See product_header_extensions.
