Outline of Final Research Achievements

The purpose of this study is to develop a web application to visualize historical sites and topography around them in three dimensions in Okinawa. The 3D models of the sites were generated based on photogrammetry. In addition, we developed a web application that can be used on any OS and any device that runs with a common web browser as a tool to visualize historical sites and their surrounding topography in three dimensions. The system is based on open source software and can be operated at low cost.
As a result of our research, we were able to combine the 3D modeled castle ruins with the surrounding topography, and also show ancient roads on the application.

Academic Significance and Societal Importance of the Research Achievements

沖縄県に存在するグスクは、各々が独立して構築・存在したわけではなく，立地場所の周辺環境，歴史的背景，位置関係等深い関係があるとされている．それらを明確に提示することができれば，文化的な価値向上だけでなく，観光資源としての価値の向上も見込めると考えられる．
