The cameras on our Street Roo collection team will be powered by solar panels
stitched into the back pocket of custom-made roo jackets. Images will be wired
to Google in real-time. A GPS tracker embedded into the jacket will match the
location of the kangaroo to ensure the image is accurately uploaded onto the new
Street View layer.

To ensure a seamless experience - and to avoid motion sickness - we have also
developed software that will smooth over the bouncing effect experienced with
the raw data. Users will be able to move backwards or forwards in Google Street
Roo as they would use Street View, like this:

Leading marsupial specialists undertook extensive research to ensure that the image capture activity would not interfere with the roo’s grazing, sleeping or breeding activities. The cropped jackets that the kangaroos will wear have been designed to keep the pouch area completely accessible for the joey at all times.

The deployment of the ‘roo force’ will begin today and we believe 98% of the Australian outback will be captured on Google Maps within three years.
