The purpose of this study is to examine the Korean territory, the Japanese intentions, and the perception that Japan had about Korea at that time reflected in the historical atlases published in Japan during the Japanese colonial period in Korea. To this end, the researchers investigated Katsumori Shiba, the editor of The Japanese History Atlas and the enlarged edition of it, The New Japanese History Atlas, the historical situations and the background of publication, and examined and compared the composition of the contents of both atlases. Then how the two atlases perceive Korea was looked into. As a result, it was found that the scale of some maps in the two atlases has been enlarged in accordance with the changes in times, and that Japan pursued historical justification for ruling over the Korean Peninsula through historical maps. In other words, they tried to show that Japan's dominance over the Korean peninsula was in the extension of the past, and the Korean peninsula was faithful to its role as a bridgehead for Japanese advance continent. Also, it is shown that Japan recognized basically Korea including Ulleungdo and Dokdo as ‘Chosun’.

Audio tactile map is a map that combines tactile map with auditory information. Audio tactile map can give the user direct access to the rich geographic information in a map with a supplementary auditory information. Audio tactile map can provide geographic information to visually impaired people who can’t read braille. This study shows the production case of audio tactile map. The audio tactile map produced this study overcomes the limitation of existing tactile maps’ annotation capability. It also shows that motion detection device could be adopted to audio tactile map as user interface device effectively.

Flow data have been utilized for analyzing and understating a regional spatial interaction and the dynamics of spatial organization by spatial interaction. As a classical cartographic visualization method, flow map has been broadly used for representing flow data. A flow map, however, has technical limitations such as lower readability and occlusion by representing complicated many flows. In this regard, this research focuses on an information visualization tool which has been paid attention as a new approach for representing not only non spatial data but also spatial data. We attempt to explore the applicability of a information visualization tool for geovisualization of flow data and evaluates the usability of various information visualization graphs. To do this, we utilize several graphs of Java script library of D3.js, including forced-directed graph, chord diagram, hierarchical edge bundling, Sankey diagram, and time-distance graph and present various geovisualization ways of rapid-trasit railway flows. From a result of case study, it turns out that each of information visualization techniques is able to overcome limitations of a traditional flow mapping technique in an effective way, and is quite useful as an alternative way of visualizing flow data. Also, it is expected that this paper provides a useful guideline for geovisualization of flow data, and leads a cognitive change of spatial information mapping and visualization in geography, cartography, and other areas dealing with spatial information.
