Supporting System for Spatial Analysis on Archaeological Site Information and Understanding Historical Context

The information on archaeological sites in the historical regions is a resource for us to understand the history of the places but the information and data of these sites are neither arranged nor shared for planning. The purpose of this study is to construct the methods to analyze the information on the archaeological sites and understand the historical context in a regional scale. In addition, we propose thg method to visualize the ancient environment through the technblogy of spatial analysis for the collaboration between archaeologists and city planners. Focusing on the Itoshima Region, we analyze the distributed location of the archaeological sites by GIS and spatial analysis technology. Through the analysis of the location condition of the sites, the constructed system enables to clarify the geographical condition of each type of archaeological sites and visualize the social territory of ancient environment. Finally, we construct a model of web GIS to share the database on the archaeological sites in a regional scale among people on the web. This web GIS enables us to understand the region-wide historical environment visually and to support the collaboration among archaeologists, planners, and residents for the issues on the preservation of the archaeological sites
