World map color-coded by level of touristiness, based on analysis of photos on Panoramio. Yellow indicates high touristiness, red medium touristiness, and blue low touristiness. Areas having no Panoramio photos at all are grey. The analysis takes into account how many photos and by how many authors there are in a given area.
