    A Study on the Geographical Information of East Asia Represented in Catalan Atlas

    JUNG,IN-CHUL | 2015, 15(2) | pp.1~14 | number of Cited : 3
    Abstract
    The purpose of this study is to explore the geographical information of East Asia represented in Catalan atlas. The labels in Catalan were translated and interpreted. As a result, it was assured that the travels of Marco Polo, John Mandeville, Friar Odoric, and Ibn Battutah were referenced. The regional information with travel story references were relatively accurate, and regions not in travel stories had ancient sources and legends as references. the Monstrous races were refuged in East Asia. Literature research led to the result that the place name ‘Caulij’ referred in Taprobana was actually representing Korea. But in Taprobana, information about Ceylon, Sumatra, Japan and Korea were mixed. The use of the annotation of catalan atlas in humanistic approach was also commented.

    A Bibliographic Analysis on the Seoul City Map of the U.S.A. Military Government in Korea

    Lee Min Boo , Kirl Kim | 2015, 15(2) | pp.15~23 | number of Cited : 0
    Abstract
    Korea had experienced the recession of the map publishing and cartography from 1945 of liberation to 1954, one year after Korean War in Korea. Korea could not have an independent interest on mapping about national territory for approximately 10 years due to a series of the periods of liberation, under-control of the U.S.A. military government, and Korean War. The only map used at that time was one for the military of the U.S.A. The most popular map open in the online is now located in the University of Texas at Austin and was produced by the Army Map Service in 1946 and 1951. The map of the military government in the U.S.A. re-edited by using UTM coordinate system in 1951 is a rare and so valuable document. It provides very useful information for the research on the military operations and the changes in geomorphology and urban landscape in Seoul. The purpose of this study is to analyze the Seoul map produced by the Army Map Service in 1951 bibliographically. Thus, firstly this study simply investigates the development process of the military map. Secondly, the maps of the military government in the U.S.A. will be compared. Thirdly, the basic components of the maps will be investigated by coordinate system, scale, direction, projection, geographic name, administrative unit, legend, source, application, and meaning of hand-written marking. In the near future, this study on the maps of the military government in the U.S.A. will be the research bases for land cover and use, geomorphic change, and urban landscape in Seoul.

    A Study on the Evolution of Korean Place Names Marked in Modern European Maps

    Kyeong Park | 2015, 15(2) | pp.25~37 | number of Cited : 15
    Abstract
    The quality and quantity of Korea-related geographic information marked on the modern European maps increased when the Huangyu quan lan tu (Atlas of the Chinese Empire) was translated and introduced to Europe by D’Angvil. Since the late 18th century, the findings from coastal and waterway survey by France, the UK and Russia were reflected in the maps, as the geographic information including the shape of the peninsula and place names became richer. In particular, the exploration by the European ships on coastline and islands resulted in large increase of exotic place names following their native languages. Place names in earlier maps were romanized after Chinese pronunciation, however, introduction of 「Chosonjeondo」 drawn by St. Kim Taegon Andrea seemed to be the beginning of the spread of place names with faithful Korean pronunciation to Europe. The map of Stieler (1872) is the firm evidence of that trend. The spread of English representation was the contribution of both diplomats Ernest Sato and Koto Bunjiro who wrote “An Orographic Sketch of Korea”.

    Linked Micromap: Exploratory Data Analysis and Geographic Visualization of Spatial Statistics Data

    Minho Kim | 2015, 15(2) | pp.39~50 | number of Cited : 4
    Abstract
    Graphic elements, e.g., bar and histogram, have been widely utilized as a tool of information visualization for the exploratory data analysis (EDA) of spatial statistics data. Meanwhile, conventional thematic map such as choropleth and flow maps has been considered to be an efficient visualization method in discovering the spatial distribution and pattern of georeferenced statistics data. However, the interest of linked micromap (LM), first proposed in statistics academia, is being grown as an useful method for EDA recently. This research implemented the LM with R programming language in order to visualize spatial statistics data information of Seoul Metropolitan City, and it provided some results of LM implementation. In addition, this study evaluated the distinct features of LM in comparison with conventional thematic maps. LM-based visualization is anticipated to gather more interests in many academic fields due to it’s functional ability to minimize information loss of spatial statistics data.

    A Study on Determining a Locational Priority for Publicly Purchasing Unexecuted Park Sites Considering the Level of Service Benefits

    Lee, Gyoung-ju , Ahn, Myung June , 이상민 | 2015, 15(2) | pp.51~65 | number of Cited : 7
    Abstract PDF
    As the sunset law enforcing the deregulation on the long-term unexecuted urban park sites approaches to be in effect, local governments need to determine where to put a priority in releasing the regulation. To make appropriate decision-making on this matter, some objective criteria need to be set. This study aims at proposing a location model to determine locational priorities for publicly purchasing unexecuted park sites. The model criteria comprise equity, efficiency, and cost-benefit. Conceptual definitions of equity and efficiency are made in normative perspective, and the two norms were combined into a location priority index. Conditioned on the results from the index, cost effective sites are to listed in descending order considering the constraint to budget available. To simulate the effect of the decision made based on the model, a prototype software was written. To see the empirical applicability, the city of Daegu, Korea was tested in the software. It appears that the simulation results provide some practical policy implications on decision-making associated with putting priority in the process of deregulation.

    A Determinant Analysis on Natural Latex Yield using Geographically Weighted Regression: A Case Study of Xishuangbanna, Yunnan, China

    Kim, Oh Seok | 2015, 15(2) | pp.67~77 | number of Cited : 2
    Abstract
    This paper introduces an exploratory approach to identify determinants of natural latex yield and to investigate their spatial variation using geographically weighted regression (GWR), hoping that the research outcomes could support the regional conservation and agricultural production activities in tandem. Natural latex is an important material because it is used to produce medical supplies and tires; therefore, its global demand has increased rapidly. Expansion of rubber plantations alters the indigenous landscape of Asian tropics, and such change deteriorates the regional ecosystems. First, the global model was fitted to the data, which included georeferenced points collected from fields and other spatial layers, through stepwise selection. Next, the same variables were used in the local models. According to the global model, Annual mean temperature, Annual precipitation, Age of rubber trees, Elevation, and Aspect turned out statistically significant at the 99% level; however, the signs and statistical significances of parameter estimates from the local models were substantially different from those from the global model. It is expected that the GWR outcomes would support conservation policies and land-use strategies for Xishuangbanna as well as other parts of Southeast Asia.

    Geomorphological Maps Legend Development Plan for the Natural Environment Survey

    Hee-Chang Kim , DongHi Kwon | 2015, 15(2) | pp.79~92 | number of Cited : 1
    Abstract
    In this study, a legend and symbol development plan was proposed after classifying them into three types, i.e., applied, transformed and newly made, using the materials of Europe. It is believed that the legends and symbols proposed in this study will be considerably effective in generally identifying the morphological features of topography and the features of geographic distribution on large-scale geomorphological maps. At the same time, it is expected that the results of this study will be utilized as fundamental materials in developing legends for the preparation of ecomaps related to the national natural environment survey conducted by the Ministry of Environment. However, the topography symbols proposed in this study only stress the morphological features of topography, and they have limitations in that it is difficult to comprehensively judge the causes of topography formation of each unit, the development process and the time of formation. Thus, it is thought that they should be supplemented through follow-up studies.

    Spatial Distribution of Korean Geotweets

    Hong Il Young | 2015, 15(2) | pp.93~101 | number of Cited : 18
    Abstract
    In this study, we analyzed the distribution of Korean geotweet. Geotweet was analyzed, which was collected at November 2014 through Twitter Streaming API. Using the Python programming, it was carried out to analyze the collected data and GIS data conversion. Twitter use and distribution are concentrated at Seoul and the metropolitan areas and a few heavy users were creating a large number of tweets. Time series analysis showed the characteristics of the tweets that make up the highest point on the Weekend and forms the highest point at 14:00 during the day. In addition, differences in the content that appears every high percentage of retweets and regions through text analysis were also identified.
