    A Map Analysis on Northeast Asia in Western Major Historical Atlas: Focusing on Cartography and Historical Geography Issues

    Kim, Jong-geun | 2018, 18(2) | pp.1~21 | number of Cited : 0
    Since the 19th century, numerous modern historical atlases have been produced in the Anglosphere, and its tradition has been maintained to this day. As a result, the historical atlases published in the Anglosphere are used as a key reference in the publication of the historical atlases in many other countries, including South Korea. Despite their reputation, however, these historical atlases have considerable cartographic and historical geographic problems. In this study, I analysed historical maps related to the Northeast Asian region, contained in the Times Complete World History and the DK World History Atlas. The analysis found problems such as lack of basic cartographic elements such as a scale bar, a north arrow, inappropriate representations of geographical elements such as coastlines and streams, inappropriate marking of borders, and the Korean Peninsula shape. In terms of historical geography, the exaggeration of the territories of commanderies of Han China, the question of the pronouncing of the name of Balhae Kingdom and the problem of marking of Chinese territory on the Korean Peninsula were identified. Moreover, It was found that Dokdo was not drawn, and the name of East Sea was juxtaposed with Sea of Japan with few exceptions in these two historical atlases.

    Evaluation of Representational Accuracy of Terrain in 1:50,000 Topographic Map of the Korean Peninsula

    Kamyoung Kim | 2018, 18(2) | pp.23~37 | number of Cited : 0
    The purpose of this study is to evaluate the representational accuracy of terrain in 1:50,000 Topographic Map of the Korean Peninsula, which was made during the Japanese colonial period, using the spatial analysis techniques of GIS. For this, contour lines were digitized based on the rectified image of the topographical map. The benchmark for comparison is the contour lines of the current 1:25,000 digital map. Digital elevation models (DEM) were extracted from contour lines and surface analysis, overlay analysis, 3D analysis, and hydrological analysis were performed using them. The accuracy of topographical representation was assessed qualitatively or quantitatively by means of hillshade, elevation difference, elevation profile, the location of stream networks, stream order and length, sinuosity, and the location of ridges. The main results obtained from a case study on Bukhansan and Seoraksan Mountain are follows. First, the accuracy of topographical representation around Bukhansan Mountain, which is adjacent to Seoul, is higher than that of Seoraksan Mountain in both qualitative and quantitative evaluations. Second, the map making methods such as the symbolization of special terrains and the estimation of elevation based on the triangulation resulted in different or incorrect topographical representation. Third, accessibility and observability of terrain seems to affect the accuracy of terrain representation. The south slope of Seoraksan Mountain, which is easier to access and observe than the northern slope, was more accurately represented. The accuracy difference between Bukhansan and Seoraksan Mountain seems to be related to the importance of mapping areas in colonial management and development.

    The Relationship between Natural Heritage and Nine Valleys and Eight Scenery in Korea Using Location Data and Statistics

    Eunmi Chang | Kyeong Park | 2018, 18(2) | pp.39~52 | number of Cited : 1
    Although surveys and discussion on individual natural heritage in Korea, it is difficult to find the general fact sheets for natural heritage. We collected spatial data and ran spatial analyses on one hundred ten legally-designated natural heritages and nine valleys and eight sceneries on which poetry had been written since Joseon dynasty. Natural Heritage ranged zero to 1900 meter in height, with average of 200 meter. The ratio of long axis to short axis ranged 1 to seventy- eight with a median of 2.1. Gangwon has the most number among the provinces, while Seoguipo-si ranked the highest at the level of Si, Gun, and Gu. Considering locational certainty, nine valleys and eight sceneries distributed more in Gyeongbuk and Chungbuk Provinces in the contrast of Natural Heritages. The results of various spatial analyses will be able to apply story telling materials. Considering Natural Heritage and nine valleys together, we found some overlapping cases and separated cases. We added discussion the potential studies on the relationship attribute names of geographic names to nine valleys and eight sceneries.

    Analyzing Spatial Characteristics of Stress Topics Using Tweet Data

    Aetti Kang | Youngok Kang | 2018, 18(2) | pp.53~69 | number of Cited : 6
    This study aims how to find the spatial characteristics by region on the stress sentiment and the topics extracted from tweet data by twitter users. We downloaded 503,737 tweet data from July 12, 2014 to July 21, 2015, but analyzed 332,328 tweet data excluding advertisement and news. We classified tweet texts into morphemes in order to analyze the tweet data and applied the topic modeling based on LDA algorithm to search the topic about stress. As a result, 15 topics were generated and classified into 3 categories such as causes, results and relief methods of stress. The topics related to causes of stress are “personality”, “learning”, “job”, “family”, and “SNS use”, those related to results of stress are “illness”, “mental status”, “hair loss” and those related to relief methods of stress are “painting”, “gaming”, “exercise and cultural life”, “food intake”, “music”. Tweet data that home location are clearly identified are only 1,035 among 332,328 tweet data. So, we geolocated 34,641 tweet data through the residence model. We analyzed the results of the topic modeling by using 17 administrative districts (Si-Do) and then identified maximum and minimum number of topics. Finally, we compared which topics are highly interested in 17 administrative districts according to causes, results, and relief methods of stress. This paper is meaningful in two folds: First, this paper shows how to represent the meaning of people's sentiment which is the social pathology of stress. Second, this paper extends the field of spatial data by mapping invisible and emotional phenomena.

    Cheol Hyun Lim | Hong Il Young | 2018, 18(2) | pp.71~83 | number of Cited : 0
    Cloud computing are increasingly needed to simplify system operations and maintenance, reduce costs, and respond to rapid business changes. In this study, we analyzed the operation and suitability of UPIS cloud computing. As a result of the analysis, it is not feasible to apply the existing UPIS to cloud computing. However, in view of the sharing of the redundant infrastructure which is a problem in the current operation and the rapid response to different environments among the local governments in the dissemination of the standard system.

    The Incongruity of Metropolitan Transit Station Names Related to Administrative District Name in South Korea

    Song Hoyul | 2018, 18(2) | pp.85~106 | number of Cited : 2
    Although the history of metropolitan transit system(MTS) in South Korea has lasted 44 years, there is a dearth of research about MTS station names. As a result of reference review, there were several researches conducted about basic characteristics of MTS station names in South Korea. Therefore, writer analyzed the incongruity of 1,033 MTS station names in South Korea as in-depth research. However, in this research, writer analyzed only 630 MTS station names related to administrative district name, since there are too many MTS station names and also characteristics are different from where they related to, such as administrative district name, physical place name and socio-cultural place name. Writer considered various aspects (such as regional representativeness and the change of administrative district) in a comprehensive way, since it is not appropriate to decide the incongruity of MTS station names by only inclusion or only distance. As a result of the incongruity ratio analysis, station names related to city·county·borough is very low at 8.33% and station names related to town·township is greatly high at 39.01%. And station names related to pseudo-administrative district is very high as well at 45.45%, station names related to village is very low at 9.09%, and station names related to old administrative district is considerably high at 19.51%. We will try to reduce unsuitable station names by considering the results of this research thoroughly when we establish or revise MTS station names.

    French Navy Ship La Capricieuse’s East Sea Exploration and Map Making

    Ogcheong Ahn | Saangkyun Yi | 2018, 18(2) | pp.107~123 | number of Cited : 3
    The purpose of this study is to review the process of the East Sea exploration by the French frigate, La Capricieuse, which has been received little attention despite its great contribution to the East Sea exploration and cartographic development after the discovery of Dokdo by the French whaling ship, Le Liancourt. In particular, this article aims to shed new lights on 1) Captain Roquemaurel's experiences at East Sea exploration under the French Navy Department, 2) the growing awareness of Dokdo, and 3) the state of cartographic works in the West during the first half of the 19th century. The results of this study are as follows: First, although Captain Roquemaurel heard the discovery of Dokdo from Le Liancourt, he refused to mark the islet on a map due to the issue of trust between the governmental exploration ship and the private whaling ship. Second, as a result of the East Sea exploration, Captain Roquemaurel found considerable errors in the British explorers' information and decided to re-explore the east coast of Korea. Third, the maps published by government agencies reflected latest information promptly whereas the maps published by private cartographers were remarkably delayed. Fourth, some Western explorers from different countries met in some hub port towns, such as Hong Kong and Nagasaki, to share up-to-date geographic information with one another at that time.
