Test your iPhone....(c;

I sail so am always interested in marine charts of the USA.

Found this website which is really cool, but will cost money to access in
the future as it say demo:

Any sailors can appreciate this really cool website that lays a TRANSPARENT
NOAA marine chart over Google sat or Google maps, your choice. The
transparency controls are in the upper right corner of the app.

This thing is really processor intensive and takes a lot of bandwidth to
download both google's tiles and the chart tiles when you move in any
direction. It selects the proper chart for the altitude you select on the
google map and overlays it with javascripts, which I think iPhone still
supports.

It maxes out my N800 running quite slow but makes a perfect chart overlay
over the Google maps/sat photos. Looking at the chart for Charleston
Harbor, I see things that are only on the latest charts available so the
data is very fresh, fresher than the latest chart plugs for the
chartplotters on the yachts.

I've pointed the hackers who wrote Maemo Mapper, our best tiler, to the
website to see if we can integrate MM to these charts like they did on the
runwayfinder.com aeronautical charts, which we can display with our
position, course and tracking for the whole planet. MM either uses map
tiles you've stored on one of the two big memory cards, or can download on-
the-fly, as needed, from an internet connection. For air travel use, just
download the sat, map and aeronautical chart tiles prior to flying and you
can chart the planes position/course/speed, etc., in realtime, by putting
the little GPS BT puck in your seat window. The look on the captain's face
as he tours the cabin when he sees your chart display moving on the tablet
is priceless....and may get you a free tour of the cockpit!...(c;

Way cool website to get overlaid charts....even if it won't track you on
them.......well, yet.....(c;
