The guy who came up with this uses "data from the public Flickr and Picasa search APIs to map where photos have been taken in different cities".
"Blue points on the map are pictures taken by locals (people who have taken pictures in this city dated over a range of a month or more)." "Red points are pictures taken by tourists (people who seem to be a local of a different city and who took pictures in this city for less than a month)." "Yellow points are pictures where it can’t be determined whether or not the photographer was a tourist (because they haven’t taken pictures anywhere for over a month). They are probably tourists but might just not post many pictures at all." On 2/19/2015 5:01 PM, Igor PDML-StR wrote:

Kenneth Waller http://www.pentaxphotogallery.com/kennethwaller ----- Original Message ----- From: "John" <[email protected]> Subject: OT: Locals & Tourists I ran across this and thought the list might find it interesting. Someone made maps using geotagging from photos posted on-line to show where people make photographs in various cities. The maps show where tourists take photos (in red) compared to where the locals take photos (in blue). Yellow points are pictures the artist couldn't figure out whether the photographer was tourist or local. https://www.flickr.com/photos/walkingsf/sets/72157624209158632/ It would be nice if this could be called up as some kind of overlay in Google Maps (or other on-line maps) so you could zoom in.
