“…One possibility for measuring visitor flows in destinations quantitatively is via the use of different ICT-based tracking technologies. Various tracking datasets have been applied to the study of tourism and tourist movements, including mobile positioning data (e.g., Ahas, Aasa, Roose, Mark, & Silm, 2008;Calabrese & Ratti, 2006;Nilbe, Ahas, & Silm, 2014), GPS data (e.g., Grinberger, Shoval, & McKercher, 2014;Shoval & Isaacson, 2007;Shoval, McKercher, Ng, & Birenboim, 2011), bluetooth data (e.g., Versichele et al, 2014;Yoshimura et al, 2014), user-generated data such as geo-located tweets from Twitter (e.g., Hawelka et al, 2014), and georeferenced photos from the photo-sharing webpage Flickr (e.g., Girardin, Fiore, Ratti, & Blat, 2008).…”
