Extraction of Viewable Point from the Photograh Data with Location

There are many researches of a route navigation that regards efficiency such as avoiding traffic congestion or finding the shortest routes. On the other hand, in navigation for a sightseeing tour, it is important to consider not only the efficiency but also amusement. In this study, we investigate route recommendation that considers landscapes in order to realize a navigation that regards the amusement as important. Particularly, we propose a method that extracts distant view spots, which are spots people can enjoy in the distant, and then extracts viewable points, which are places people can see the distant view spots. We focus on distribution of photograph data with location from photo-sharing sites such as Panoramio. Our method extracts the distant view spots and the viewable points based on their distribution. In this paper, we show experimental results using real data and discuss relevance of our method.
