    I guess this is an awkward suggestion, but thinking outside the box, it could work.

    I've seem some applications that use the movement of the iPod to track speed, such as an Accelerometer app you use to tell how fast you're going in a car. Through using Google maps to pre-load your entire trip, directions and all, would it be possible to make a GPS application that can be used completely offline? The accelerometer would allow the "GPS" to know how fast you're going, therefor keeping your directions/visual up to date. If the accelerometer messes up at one point or another, you'd be able to reset your position on the road/highway through the cache.

    Good idea? Bad?

    I don't think an iPod could track distance or speed.

    There was an flash image for my SE w910 that also had an accelometre and it could show you speed and distance


    sorry for my bad engl

    Hmm.

    Could work, but the more you use it, the accuracy will decrease until it is unusable.

    I think in conjunction with ongoing location updating through wifi (via skyhook), this has some merit.

    i dunno if the iPod can detect if you are turning?
    i think only forward speed.

    needs compass

    the accelerometer can only detect scalar quantities like speed and distance. velocity and displacement, however, are vector quantities, so the app will need to know what direction the device is moving along (through a compass input maybe?). now it just becomes a path tracing problem.
