Potential of Digital Elevation Topographic Maps reveal the history of the region: comparing Those Maps with Marsh data in the early Meiji Period

Abstract. Landform of lowland is remains of the natural disasters and the history. Residents of this area are influenced of the landform with history of natural disaster. Therefore, there is an inseparable relationship between topography and social life. At Geospatial Information Authority of Japan (GSI), we are creating Thematic maps which clearly express topographic information. We also create, Thematic maps which distinguish the topography from the formation of the land. New findings can be obtained by considering these thematic maps in combination.

In this paper, we study the relationship between landform and history of Tokyo by comparing “Digital Elevation Topographic Map” and “Marsh data in the early Meiji Period”. (This early Meiji Period here is the 1880s.)
