| Outline of Final Research Achievements |
Spatial data of historic geographical features boundaries between countries, counties or villages are required for using GIS (Geographic Information System) in the historical studies. However, such historical boundaries have often kinds of uncertainties; they depend on periods or researcher’s opinions. Sometimes they include undefined parts. Therefore historical boundaries, especially those before Edo Period, have rarely been digitalized to spatial data. In this research, a method for semiautomatic generation of the boundary data using the Voronoi division is proposed. Where rough shapes of the core domain is initially given. Experimental comparison of the proposed method and an existing method is presented. The proposed method gives similar output to existing method with about 20% of workload.
