Google Maps have introduced an indoor version of their street maps and it has great possibilities for retailing.
In fact most of the indoor sites listed for Australia are shopping centres. How does this work? Shopping centres upload floor plans of their centres to Google. Standard GPS location services don't work great indoors so Google links those plans with local wi-fi and telephone tower facilities. Once set up, customers can locate themselves within the building and use the maps to guide their shopping experience. In the CBD, Melbourne Central, and The Strand Arcade have the indoor map facility.
QVM's confusing spread of halls, sheds, shops and outdoor locations would seem to be a perfect target for this type of technology and linked with a database of stall/shop locations could be of great benefit to customers and traders.
