Types of products
- DUMPWISE products: products (processed to the required level) with the same ground coverage as the raw data downloaded by the station which means products of very different sizes.
- ORBITWISE products: combination of different DUMPWISE products to reconstruct a product of fixed size (from equator to equator). All the ORBITWISE products corresponding to the same orbit of the cycle are stackable.
