Google Offers Hybrid Satellite and Map View
That's Unpossible! writes "Google Maps now offers a hybrid view which combines their map view with their satellite view. The Google blog has a notice on the update. It appears to use 8-bit alpha transparent PNGs to make it work."
They've had arrows pointing out traffic flow for a while now... as far as I know. (Because I used it a while ago to see traffic flow for a certain city...)
Mapper of Doom has had this for quite some time, albeit with existing data from Terraserver.

/. is good for you.
They added a scale since the last time I checked the maps, too! Halleluah!
It's pretty neat - the satellite photos are no longer wrapped around a cylinder (making places far away north or south from equator look squished).
Unfortunately there still isn't maps available for Europe besides England. I hope it would arrive soon.

There are a couple of different ways to achieve transparent PNGs in IE - besides simple 100% transparent colors (as known from gifs). The Google overlay isn't simply 100% transparent. The same goes for the "speech bubble" when clicking on different places.

There are a couple of different methods. The Google Maps API mentions one:

OK, so as sort of a meta-reply to all the posters asking about IE and PNG support, here's 2 interesting hacks you can use to get your PNG magic rolling in MSIE.
MSIE (as of v6) doesn't support 32 bit transparent PNGs natively, but there is a cool hack where you can dither them down to 8 bits, retaining translucenct for browsers that support it, and using 1-bit transparency in MSIE, so it still looks OK.
Alternatively, you can use the AlphaImageLoader() filter for near native IE PNG support -- that's a link to my own free CSS behavior that automatically adds IMG and background-image support for PNGs to MSIE 5.5+.
Either way, PNGs rock, except for the lack of a cross-platform gamma standard -- if you need to match other colours on your site, just use JPEGs/GIFs.

The accuracy of the overlay seems to vary according to the elevation of the area and also the image itslf.
Because of the fact that sattilites can only zoom in so far and still have a good image, in areas where you can zoom all the way in, they have to use airplanes to take pictures. Nevertheless, these survery airplanes have to maintain a perfect or almost perfect parallellness with the ground or else the image will look shifted. In places where the overlays are not very exact, the most common reason is than when the sattilite image was taken, the survey plane's camera was not pointing straight down and resulted in a shifted overlay in relation to the real image.
And I find his GUI better than Google's. It's slicker, and the ability to adjust the transparency (slider at the bottom) is quite innovative. As is also the ability to move the foreground or background and have the other align itself accordingly.

I too wonder where they get their data. I was looking at a couple of mapping apps a few weeks ago, playing with a GPS puck I got for my birthday, and I think one of those shows the same stupid mistakes in the streets. It was either Microsoft Streets and Trips, or it was Rand McNally Streetfinder. I don't remember which, and right now I don't have either loaded because my disk drive died...
The satellite view shows my pool, though, so - Hey!! I can see my pool from space!!
