Uh, this is Cartesian product [4], not a cross product [5], as far as I'm concerned. Cartesian product > grid > cross product.
Cartesian product is probably the right name, but it sounds too formal to me personally. I'd like this to be clear in "layman" terms. I think of grid dataset as nodes on a N dimensional grid, where each dimension represent a dataset we "multiplying". So each node of grid is sample in our grid dataset. Gennadiy
