ViTFlow: A platform to visualize tourists flows in a rich interactive map-based interface

In this paper, we describe ViTFlow, a platform to visualize tourists flows, integrating different data sources into a rich interactive map-based visualization. The data are collected using low-cost routers, enabling wi-fi passive tracking, and sensors, detecting environmental conditions, spread over the Madeira Islands. Different types of data can be visualized in the map-based interface, including spatio-temporal mobility data (i.e., movements between places and common paths taken by tourists), airplane and cruise ship traffic, weather information, and official events. We designed the interface with the aim of providing citizens and tourists with a public display to facilitate a dialog between the different communities, exploiting synergies to promote the sustainability of the archipelago.
