The dark areas have no photos attached, the blue areas have a few photos, the red areas have more and the the yellow areas have a large number of photos geotagged.

The Estonia heatmap uses the number of all photos uploaded to Panoramio for a given area. The Tallinn heatmaps use the coordinates of the actual photos available from Panoramio. The Old Town heatmap shows a blue square only on the spots with at least two photos available.

The foursquare locations are generated by the Foursquare users. Popularity is estimated by the number of different users, not the number of checkins. We show only the locations with at least 4 different users for touristic location types (selectable as "seeworthy"), at least 50 for moderately touristic location types and at least 400 for all the others.

The visitestonia locations are generated by the team led by the Estonian Tourist Board, containing a large number of members from different Estonian regions. The location popularity is currently not estimated. The selectable types are based on the more fine-grained visitestonia object types. The visitestonia site contains a large number of events, not shown nn the current map.

The Estonia and Old Town heatmaps contain very little noise: bright spots on the map correspond surprisingly well to the "intuitive" touristic popularity of the area. The Tallinn map is mostly adequate but contains two bright noise spots at 59.4339/24.728 and 59.4046/24.805 with a number of generic Tallinn photos mistakenly geotagged to these coordinates.

The maps were created for the personalized tourism recommender project Sightsplanner with the eventual goal is to automate the calculation of the popularity of each point of interest.

See the the heatmaps for the whole world!

The world touristiness map by Ahti served as an inspiration for this project.
