Have you ever wondered what countries are the most and least frequented by travelers? Estonian tech firm Bluemoon has taken data from the photo sharing service Panoramio and created a heat-map based on photos. The map details which countries are the most visited (in yellow), which have a medium amount of visitors (in red) and which are explored the least (in blue). A grey area signifies that no photos have been taken there using Panoramio.

As you can see from the map, Europe is a major tourist destination, as is much of the east and west coasts of the United States and Japan. Certain regions that seem to receive few visitors include Mongolia, India and Australia. Moreover, many areas in Canada and Africa remain unexplored.

They've also created a map of the "world's most interesting remote places." It only looks at destinations away from cities with remote tourist attractions. Some examples from the data show the Greek Islands are touristy (red), the Amazon Basin has almost no tourism (green) and Ladakh falls in the middle (yellow).
