    A Study on the Fossilized Toponym of Naepo Region - Focused on Sapgyocheon Riverside of Dangjin -

    Song Hoyul , 김추윤 | 2015, 15(3) | pp.1~22 | number of Cited : 1
    Naepo region located in the west coast of Sapgyocheon had the most exclaves in Korea during Joseon Dynasty era. Like most regions of the country, its administrative districts were significantly consolidated in 1914. Although many toponyms became extinct in the process of administrative district reorganization, unlike other regions, peculiar types of fossilized toponym became co-exist in eastern part of Dangjin which was Myeoncheongun before, because of the unique regionality of Naepo region. As a result of research, Hongju Bukchang, Hongju Cheonggeum, Deoksanchon, and Bibangguji were verified as examples related with exclave(wolgyeongji) and Beognae(Beomcheon), Changtaek, Gahwa, Deokmeori(Deokdu), Seungseon, and Songol(Sondong) were verified as examples related with administrative district reorganization. In order to preserve the old toponyms which is gradually disappearing, more active endeavor of related officials and researchers is required.

    Establishing a Map Sheet Naming Principle for National Topographic Maps with Its Application to 1:50,000 Topographic Maps in Korea

    Cho Daeheon , LEE, SANG-IL , Jin-hyuk Kim | 2015, 15(3) | pp.23~38 | number of Cited : 2
    The sheet names of national topographic maps serve as an index for the efficient management and search of map sheets as well as a georeferencing system to inform the location of the area that they cover. Although national topographic maps have been compiled over 100 years in Korea, there has been very little research on the sheet names of topographic maps. The purpose of this study is to establish a map sheet naming principle for national topographic maps and to examine existing map names on the basis of the proposed principle. The main results are as follows. First, practical ways to establish the principle for the map sheet naming are suggested in accordance to a discussion on the importance of the principle. Second, the principle for map sheet naming to prioritize the administrative unit names is developed based on existing map names. Third, an examination is undertaken for the names of existing 1:50,000 national topographic maps with respect to the proposed principle, suggesting that around 20% of the current map names need to be renamed. The proposed principle is expected to provide an effective foundation on which new maps are named and existing maps are renamed as well.

    Implementation of a Gesture Library for Manipulating Smartphone Maps

    Soo-Jin Lee , Hyung Woo Kim , Yang-Won LEE | 2015, 15(3) | pp.39~48 | number of Cited : 2
    With the development of information technologies, touch screen-based mobile devices like smartphone and tablet PC have been widely provided. These smart devices usually employ touch gesture, which is a simple and intuitive way of interaction such as tab and pinch on the screen. In this paper, we implemented a gesture library to manipulate smartphone maps for improvement of user access to the web map services. Our gesture library included the functionalities for touch gesture, air gesture, and joystick gesture that enable more convenient manipulation of smartphone maps. We also built a prototype application to test the feasibility of our library and made sure each functionality for gesture interface worked properly. Because our library consists of several objects and functions that can be easily used by program developers, a variety of smartphone apps with gesture interface can be implemented simply by liking web maps. Our library includes a novel method for gesture that has not been tried for smartphone maps and can be extended in the form of HTML5 which allows for an OS-independent library for smart devices.

    The Cartographical Significance and Legacy of the International Map of the World (IMW)

    LEE, SANG-IL , Cho Daeheon | 2015, 15(3) | pp.49~62 | number of Cited : 3
    International Map of the World (IMW) is the human beings’ first global mapping project which aimed at compiling a general-purpose map series composed of almost a thousand of topographic map sheets covering the whole landmass in accordance with a common scale (1:1 million), a common map projection(Lambert conformal conic projection), and a common mapping specification, but ended in failure in 1989. IMW is indeed a gigantic event in the history of cartography which can be seen from the fact that it was recognized as one of the best maps in the 20th century and one of the greatest maps in the whole history of cartography, and the year 1891 when Albrecht Penck officially proposed the project was conceived of as the beginning of the modern cartography. The cartographical significance of the IMW project is threefold. First, IMW became the exemplar for many of the ensuing global mapping projects as the Digital Chart of the World and Global Mapping. Second, IMW provided a standard mapping specification for topographic maps (especially with respect to map projections and hypsometric tints). Third, IMW offered a foundational framework for topographic map indexing. The IMW indexing system which was originally designed to denote the IMW grids each of which is 4° of latitude and 6° of longitude has become the predominant convention for topographic map indexing in many countries. This, the most prominent IMW legacy, is exemplified by the topographic map indexing systems practiced in such countries as South Korea, Japan, Australian, United States, Russia, and Canada.

    Minsung Kim , Changho Lee | 2015, 15(3) | pp.63~77 | number of Cited : 12
    Abstract PDF
    The purpose of this study was for university students to participate in their community and to provide useful services for the local residents. Furthermore, this research examined whether the completion of this project contributed to enhancing students' understandings of geographic concepts and the capability to use geospatial technologies. The participants developed a digital trail of Gwanak Mountain. In developing the trail, concepts regarding geotourism, geomorphology, and community participation were incorporated, and geosptatial technologies, such as GIS, GPS, and Google Earth, were used. As a result, a digital output containing components, such as photographs, animations, and explanations following the trail, an environmental game, and the difficulty of the route, was produced. The participants increased their confidence in understanding geographic concepts related to the project and developed their ability to use geospatial technologies. The persons concerned in the community responded positively to the project.

    The Effect of UNESCO World Heritage Listing on Chinese Tourism Migration using Geotagged Panoramio Photo Collections

    Bae Sunhak | 2015, 15(3) | pp.79~89 | number of Cited : 1
    This study investigates the UNESCO world heritage listing effects on visitor’s number and seasonal preference by using the frequency of Google Panoramio geotagged photo collections and its registered time information in China with GIS. The result shows that world heritage listing doesn’t significantly affect the number of tourists. However, there are significant differences in the number of geotagged photo collections between different seasons from monthly perspective and different locations of the world heritage sites. Considering the UNESCO World Heritage is one of the important tourism attraction resource in China, these results may depict the tendency of Chinese tourist’s migration and it would be possible to use geotagged photo collections as an indirect index for tourism migration trend analysis.

    Spatial Patterns of Industrial Activities in Seoul Under Japanese Colonial Powers: Based on Ethnically Segregated Residential Distribution

    Changwha Oh , Kim, Youngho | 2015, 15(3) | pp.91~100 | number of Cited : 1
    Abstract PDF
    This study investigates spatial patterns of residence and industrial activities of Korean and Japanese ethnic groups in the 1930s. The 1930s is characterized as rapid industrialization periods in Korean peninsula. Particularly, Seoul was the core of the industrialization process. This study analyzes and compares spatial patterns of industries based on Korean and Japanese residence at the time. Seeing the previous studies about spatial patterns about socio-economic activities in the Japanese colonial period are qualitatively driven, this study uniquely applies quantitative spatial analysis methods for the analysis. The results show that Seoul had distinctly clear segregation patterns among different ethnic residences. And this segregation attributed to industrial segregation by ethnic groups. However, spatial distribution of industries reflect not only residential segregation but also many other factors such as land cost and life styles.

    A Study on Selecting Measures for Test-Bed Subject of Intelligence Security

    Sunhee Han , Jae Yong Lee | 2015, 15(3) | pp.101~111 | number of Cited : 5
    Security technology to reduce crime rate has been attract the worldwide attention. In particular, building-up security application and surveillance camera system (CCTV), as a national key project, are promoted in nationwide. However, due to the low effectivity of security application and CCTV such as crime arrest rate and overloaded surveillance by CCTV monitoring agent, the necessity of the intelligence security technology has gradually increased. However, the concerns over testing on its validity make it difficult to apply the intelligence security technology to local governments. Besides, it should consider the other matters such as overcoming various legal constraints, feedbacks from citizens, and cooperation among relevant organizations in order to make successful crime prevention. In this regard, it would be important to establish the test-bed in real environment where citizens live, for testing intelligent surveillance security technology and its validation. After getting validation from the test-bed, it also would be better for commercializing the technology. Hence, standard for selecting test-bed as the first step of establishing successful test-bed is important. Therefore, this study aims at objectively providing considerations and standards in selecting test-bed in real environment which is subject to 'Intelligent Security Technology R&D Projects' which is different from previous R&D. This study also contributes to selecting the test-bed in real environment which is expected to be expanded over time.

    Image Fusion on High Spatial Resolution WorldView-2 Satellite Data

    Minho Kim | 2015, 15(3) | pp.113~126 | number of Cited : 0
    Many image fusion techniques have been developed to produce high spatial-resolution color imagery from panchromatic (PAN) and multispectral (MULTI) satellite imagery. The conventional techniques could be subdivided into three categories such as spectral substitution, arithmetic merging and spatial domain. This research applied fusion techniques, corresponding to each fusion category, to PAN and MULTI scenes of WorldView-2 satellite. Individual fused images were evaluated in terms of spectral and spatial distortion. The study found that fused imagery, based on spatial domain, were superior to those fusion results from spectral substitution and arithmetic merging. It is anticipated that spatial-domain fusion technique would be appropriate in producing fused imagery that could play a role of input data for online image map as well as thematic map at a large scale.

    Map Error Analysis of High School Social Studies Textbook

    Jeong, Jae Joon | 2015, 15(3) | pp.127~141 | number of Cited : 6
    Social studies textbooks first, depending on the role and frequency of maps, are classified 3 categories; 1) social studies or ethics in which maps are used collateral material, 2) history in which maps contain location information of historic events, 3) geography in which maps play key roles in delivering curriculum contents. Generally, maps in geography textbook made by teachers or professors majoring geography are generated according to cartographic rules, and properly. But many maps in social studies, ethics, and history textbook have incorrect map projection, missing inset map, and wrong map legends. As results, maps containing errors may lead distorted national territory recognition of students. In the research, map errors in social studies, ethics, and history textbook are divided in geometric errors, inset map errors, and wrong legends. Analysis shows that 352 maps in total 1085 textbook maps contains map errors. Geometric errors are the most abundant with 20.8% and ratio of inset map errors and improper legends are 6.8% and 4.8% respectively. In order to prevent generating map with errors, systematic and institutional procedures are essential in textbook authorizing and standard databases used in textbook map writing are urgently prepared.
