It would be helpful if ESRI could provide accurate fly dates, or at least years, for the online imagery. I've been using the "I" query to get the dates and taken those at face value. But recently I had a project where the imagery showed structures that I know were removed several years ago yet the imagery still shows them. So I know the date of May 2014 is not only wrong, the imagery is many years old. Maybe the dates are when the imagery was acquired. But not flown. And to make things even more frustrating, in one case water behind a dam appears and disappears depending on the scale. I will have to stop using the online imagery unless these problems are fixed.
