**3.1. System configuration-**

The system of the present study is developed by means of Web-GIS, an SNS, and a registration system of walking information, as shown in **Figure 1**. The system enables to visualize the information related to outlines, height, and sightseeing spot on the digital maps of the Web-GIS.-Therefore, it is possible for users to efficiently obtain the necessary information related to walking. Since the system is connected with external SNS (Twitter), it is possible for users to share various information related to walking, and displaying the tweets with a specific hashtag submitted by others. Additionally, it is also possible for users to register their walking information such as the number and time of their steps. Users can freely confirm their registered information, which is maintained in the database of the system.
