The remarkable developments in tracking technologies over the past decade have opened up a wealth of possibilities in terms of research into tourist spatial behaviour. To date, most research in the field has been based on data derived from less objective – hence methodologically problematic – sources. This book examines the various technologies available to track pedestrians and motorized vehicles as well as the moral, ethical and legal issues arising from the utilization of data thus obtained. The methodologies outlined in the book could prove revolutionary in terms of tourism research, management and planning.
