Hands-on with Google's Tracker Street View backpack

  The 30-pound [backpack] is essentially a modified version of the same
  setup Google has long used on its Street View car fleet. Up top are 15
  5-megapixel cameras that are constantly shooting, and the GPS that's
  normally in the car has been added here as well -- two of them,
  actually. However, Google wants Tracker to work in places where GPS
  doesn't, so it has added an accelerometer for more direct movement
  tracking. If GPS is unavailable, the accelerometer and compass will
  help keep the images it captures aligned.

"Street View" for malls and walking paths?

How long until someone creates a D-I-Y version of this and starts
mapping out hiking trails?
