• 論文抄録 / 内容記述: In Akita Prefecture, Japan, many Bon Odori dances (Bon Odori: one of the Japanese folk dance categories) have been passed down in respective regional communities. To visualize relationship between the regional motion-characteristic variation of Bon Odori dances and the geographic elements of corresponding regions in Akita Prefecture, a technique of map deformation was introduced in a previous study. As a result, a deformed map having the style of distance cartogram was constructed. However, the geometrical characteristics of the original geographic elements, e.g., the smoothness of the original shapes, were not necessarily maintained. In this study, we apply a technique of moving least squares transformation to the Bon Odori distance cartogram construction. This technique guarantees globally smooth deformation. We also propose a new performance index quantitatively evaluating the degree of deformation of the obtained cartogram. This is introduced to avoid excessive deformation that deteriorates the readability of the cartogram. Experimental results demonstrate the effectiveness of the proposed approach to a certain extent.
