For some reason, the article is inaccessible at the time of writing, but it seems to be using a military satellite to map ancient (and presumably shallow) underground water canals for archeological purposes.
Spy satellites surveying Iran in order to detect underground water infrastructure seems like, to me, the ulterior motive is to identify infrastructure so that it can be compromised in some way, likely with drones and bombs.
