1. What is "advanced discovery"? Because Japan is an island country, there are many landforms where the tip of the land such as hills and mountains protruded to flatlands, oceans, lakes and the like. Many appear in the peninsula and the tip of the island, such places are scenic spots or power spots. "Discovery of the tip" judges the terrain of Japan by machine learning, and makes data of extreme terrain all over Japan. There are many famous scenic spots, such as Tojinbo and Amanohashidate, but I think that it will lead to the discovery of a new charm by discovering a notorious topography that is not well known elsewhere. We also made it possible to provide judged data in RDF format. The place where you can discover new sightseeing spots by connecting the location of these tips to the sightseeing data is uniqueness of this dataset. 2. Method of judgment by machine learning ① Judge land or sea at 2.5 km intervals from the edge of latitude and longitude in Japan to the edge. ② Judge whether the point of 5.0 km ahead is land or sea 60 degrees at a time from the point judged to be land. Measure the hexagonal point. ③ Extract the location where the number of land is 2 or less as the tip point.
