    Jaeyung Choi | Saangkyun Yi | 2017, 17(1) | pp.1~13 | number of Cited : 1
    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’.

    Exploring Geovisualization of Flow Data Using a Web-based Data Visualization Tool

    Jiwoo Kim | Lee, Gunhak | 2017, 17(1) | pp.25~39 | number of Cited : 6
    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.

    The General Characteristics of Boulevards in South Korea

    Song Hoyul | 2017, 17(1) | pp.41~58 | number of Cited : 3
    Since Jan. 1st 2014, the road name address system became mandatory in South Korea. However, usage of the road name address system fell short of expectations and also research about this system is quite insufficient. Therefore, writer got ‘road section report’ from 17 different local governments and then only extracted roads which was classified as boulevard. Based on that, writer analyzed general characteristics of boulevards in South Korea. As a result of analysis, among 288 boulevards, there are 12 pairs of boulevards which have same name with the other roads. Also there are 12 boulevards which belong authentically to two different local governments. They have common ground on that Ministry of the Interior has management authority of those roads. Total length of Donghae-daero which is longest boulevard in South Korea is 359km. Extremely long distance boulevards are very relevant with national highways. Total length of Inhang-ro which is shortest boulevard in South Korea is 470m. Extremely short boulevards usually belong to single ‘dong’. There are 8 boulevards which named like normal roads (‘ro’) not as like boulevards(‘daero’), because those boulevards have one thing in common that they named after existing roads' name. There are 141 roads which are narrow road but rear part of road name misleads those roads into boulevards or which are broad enough and have road name ended with ‘daero’, but classified as normal road (‘ro’). Those roads can be classified into 2 types, broad roads which are as wide as boulevard and more narrow roads than two-lane road.

    Requirements Analysis for Teaching with Geospatial Technology and Provision of Educational Services for K-12

    Youngok Kang | 박지영 | 2017, 17(1) | pp.59~69 | number of Cited : 4
    Creative and convergent education is emphasized in the information society of the 21st century. In the case of overseas, STEM (Science, Technology, Engineering & Mathematics) education is emphasized as a representative form of creative convergence education, and geospatial technology is recognized as a very important factor as an element of STEM education. As a result, the geospatial institutions in U.S. and U.K. have provided the education contents and services based on geospatial technology in the K-12 level. In Korea, the importance of creative education has also been emphasized in recent years. However, creative and convergence education based on geospatial technology that can be positioned at the core of education is insufficient. This study focused on the strategy development so that the geospatial technology is actively used at the elementary, middle, and high school levels. In chapter 2, we examine the research related to the educational effect of teaching with geospatial technology. In chapter 3, we investigate the requirements for vitalizing the teaching with geospatial technology by surveying 300 teachers. In chapter 4, we analyze the overseas web sites that provide educational service based on geospatial technology. Based on this, we propose a strategy for educational service based on geospatial technology.

    Analysis of Spatial Pattern Changes and Its Human and Environmental Factors of the Malaria Risks in Korea

    Sehyeong Kim | Youngho Kim | 2017, 17(1) | pp.71~85 | number of Cited : 3
    Since the reemergence in 1993, spatial patterns of Malaria outbreaks of South Korea have been drastically changed while its number has been fluctuating. It is well known that complicated interactions among human, nature, and socio-economic factors influence malaria risks. This study aims to investigate the spatial patterns of malaria in order to understand and control risks from malaria. Exploratory spatial data analysis methods, including Getis-Ord Gi* and mean center, are applied to analyze the changes in spatial distribution of malaria occurrences from 2001 to 2014. Generalized Poisson regression model is applied to ecologically estimate and compare the natural and socio-economic factors related to malaria occurrences in 2001 and 2014. The distance from Military Demarcation Line explained the spatial autocorrelation of the malaria occurrences. The result shows that number of cattle, standard announced land value, sex ratio, apartment ratio, distance from MDL, climate factors, and rice paddy ratio were significant in 2001 and 2014.

    Development of an Urban Sprawl Measure Based Density-spatial Structure

    임수진 | Kamyoung Kim | 2017, 17(1) | pp.87~101 | number of Cited : 4
    Two core components of defining urban sprawl are low-density and fragmented residential development. Sprawl measures based the density could not grasp the degree of fragmentation and sprawl measures based on spatial structure could not catch the variation of density. Therefore, the purpose of the research is to develop an alternative measure simultaneously reflecting density variation and the degree of fragmentation. To achieve this, Lopez and Hynes’s Sprawl Index which is based on population density and two spatial structure based indexes, that is, joint count statistics and division index are combined with weights. These three indices have the same interpretation and range of measurement. We named this new alternative measure as a density-spatial structure sprawl index. The index is easily calculated using density, adjacency, and area of urbanized region and it’s interpretation is straightforward because indices with the same range and meaning of measurement are combined. Computational results show that the developed index can remedy the shortcomings of density-based and spatial structure-based sprawl approaches.

    Jungyeop Shin | 2017, 17(1) | pp.103~120 | number of Cited : 11
    Abstract PDF
    Coinciding with the increased attention being paid to the research of the geography of literature, the development of internet-based geographic information technology is enhancing the efficiency of analysis of, and service related to, geographic content. In this regard, in-depth analysis of geographic thought and content in existent literature, along with the geographic information technology utilized to access and use it, therefore require research. Taking this as motivation, the purpose of this article is to analyze geographic information for Jiwon Park’s, Yeolha-ilgi, using an Internet-based GIS solution. To this end, geographic thought and content from Yeolha-ilgi were explored and extracted based on five categories; location, geomorphology, climatology, regional geography, and territory/world view. Six major functions using Google Map and ArcGIS were then implemented as follows; digital map manipulation and exploration with varied scales, geovisualization with 2D and 3D maps, a combination of location information and different kinds of resources with Google mashup, elevation profiling of the trails, analysis of journey distance, visualization of the weather and trail journey distance, and linkage to related historical maps. We expect that such exercises will improve geographic understanding by building out more dynamic perspectives of literature.
