We have been constructing a GIS database of Japanese archaeological data, publishing it as WebGIS, and providing it as open data in a reusable form. The purpose of this study is to present the practice of constructing GIS databases of archaeological data and their representation using WebGIS, and to discuss the significance of constructing an infrastructure for providing data related to historical GIS in an open form, and historical GIS and open science. Japan is one of the countries in the world with a large number of excavations, and the results have been accumulated. However, only a few of them have been converted into GIS data. This study focuses on Heian-kyo site, an ancient capital of Japan, located in Kyoto City. Where the Heian-kyo site was located has been urbanized, and a lot of rescue excavations for redevelopment. However, it has become increasingly difficult to grasp the full extent of the enormous results and to access the necessary information. In order to solve this problem, we have developed a GIS database based on the archaeological data collected from each excavation unit and organized the attribute information. Furthermore, by using WebGIS, we can present a huge amount of archaeological data, and users can easily search for them. In addition, we have enhanced the accessibility of the necessary information by assigning each report information and its URL to each point of excavation.
We have also developed an open data infrastructure for archaeological data on the Heian-kyo site. By releasing the data as open data, anyone can reuse the data presented and released by WebGIS in their own environment. We will discuss how this reusability contributes to historical GIS research from the perspective of open science. It is predicted that the fields of historical GIS and archaeology will be further improved as academic research by ensuring highly transparent research and reproducibility through open science.
