I certainly need to play with it more, but my first test-run didn't impress me that much at least not as a cruising tool. I zoomed in on Moraine Cay in the Bahamas
and found the image quality so poor, it would do me no good. (The Carter's Cay group, for some reason had a lot more clarity.). I tried using their "tac" points, but when ever I tried using them for anything I kept getting error messages saying it did not recognize the street address.
Visually, the seamless presentation and ocean bottom view were pleasing, as was the ability to tilt things to a differnet persepctive. However, on a scale I'd apply to navigate local features, these new add ons did little. The actual sattelite imagry seems to be the same as I previously got with google earth
which is some cases is helpful and in others offers no detail.
My initial assessment is to give them a thumbs up on a fun ocean mapping system, but thumbs down on any improvements over the old google
earth that will actually help me, but as I said at first, I need to play with it more.
