How Long Does It Take to See Meaningful Change Overnight?

With these relatively highat revisit times, revisit rates when do you imagie that you'l have a really significant data base where you'll be able to see meaningful change overtime? So we're already capturing a fair amount of inajry on the plane in terms of meaningful change overtime. I mean, once we got eight satellites up, i think we'll have a pretty decentack catalogue of imagery already at that point. But like if you were constantly revisiting a certain scene and looking at it, i guess maybe it would take a year. Mabe, it would take two years before you had a significant sort of understanding.
