google satellite map

P: n/a
If you visit maps.google.com and select "satellite", you get a pic. But
it is not <img href="...">, and it gets quick nice response to mouse
movements and click. Does anyone know how this is implemented? I
checked the source code, looks like a ActiveX control(I am using IE, of
course). Any details about this?

Thanks,

Yes it is, it's simply images, there's no other magic involved, the
entire script is pretty simple, the only complicated thing is the edge
network of high bandwidth servers that make it work remotely timely,
the actual script is pretty simple.

There is an <Img> tag with a lot of stuff following within the tag, then
{var ret='<'+'script src="'+src+'"'+' type="text/javascript">

At a guess, that is what calls the map. There are of course a lot of
standard <img src=> tags for the icons.

I second that. The bandwidth issue can be immensely hard to solve, but
Google have got way too much bandwidth to spare. Have you heard about
Google using their bandwidth to do some caching, thereby speeding up your
browsing? If you are astounded by Google's use of satellite images, see the
program they unleashed yesterday:

Stunning stuff, I assure you. Having played with it, the bandwidth flow is
amazing.

The viewer of images is not innovative. It is based on AJAX (JavaScript,
XML). See a similar technology used for the largest image in the world (2.5
gigapixel):

I do not think it is a <Img> tag. If you right click, you can not save
it to local disk.

I can second that. I downloaded it yesterday after reading your post,
and it is quite impressive. Unfortunately its coverage of much of
Australia leaves something to be desired, but still a very impressive
little program.
