Google Adds Satellite Imagery to Maps

Ant writes "BetaNews reports that Google quietly updated its maps service late Monday to include satellite imagery, a first in the industry... Much of Google Maps remains the same - just with detailed pictures from high-tech satellites instead of standard map graphics. Maps can be dragged to view adjacent areas, which means users do not have click and wait for graphics to reload. Zooming is also instantaneous with the help of a slider placed atop the map." The resolution doesn't seem very high, but the integration is very seamless.

  1. Sounds like good technology for lots of uses by DeadSea · · Score: 4, Interesting
    Googles map software is pretty nifty. It seems like something that wouldn't be to hard to whip up for any large image file.

    I can imagine taking some very high resolution artwork and displaying it using this technology. I can zoom in to the max resolution or your can scroll around forever.

    Anybody have any software that would take a large image file and apply a google-map-like interface to it? The software should be something as simple as:

    1. Resize the image to various resolutions
    2. Break the images into 200x200 pixel chunks at each resolution and save those chunks as individual image files
    3. Put a javascript interface on

    If you are smart about your image naming conventions you shouldn't even need a powerful webserver. The whole thing could be served up via static files from a webserver with enough disk space and a big enough pipe.

    I'd like to see this for things like:

    • Local maps such as for state parks
    • Scanned artwork such as paintings - Like the Gigapixel Tapestries covered the other day.
    • Circular panorama photos that could be scrolled only in one direction

  26. Dates to mid-2002 at my house by Reziac · · Score: 4, Interesting

    I'm looking at my house right now. A tree that was cut down early in 2003 is still there. A circular path started in summer 2002 (made by exercising a horse, so it's very visible) is also there. And by the amount of greenery here in the desert, and that our veggie garden had already died off, it is probably early in the dry season. So at least in my neighbourhood, the image appears to date from about July of 2002.

    The resolution is good enough that I can see the single stripe down the middle of a nearby two-lane highway. I can also see two cars and an 18-wheeler. The smallest visible object is a 4x8 sheet of plywood atop the shelter in my corral. I can also see my kennel concrete, which at that point is 15 feet wide, represented by 5 pixels on the saved image (you can pillage them via Moz's Page Info function). So there's the max resolution -- one pixel = about 3 feet (plus or minus some blurring).
