    High School Students’ Cognitive Characteristics on the Topographic Map Symbols

    Hye-Kyoung Shim , JUNG,IN-CHUL | 2011, 11(3) | pp.1~15 | number of Cited : 3
    The purpose of this paper is to explore high school students’ cognition level of topographic map symbols and the factors which effect their perception. As a result, we found that visual form was the most influential factor in the interpretation and perception of symbols. We also found that cartographic communication was realized efficiently and positively when concrete figure symbols are engaged. Map users' learning experience and familiarity with the symbols were also important factors. But the influence of the simplicity of visual figures was insignificant. For the 43 symbols used in our study, the most positively evaluated symbols were school, aerodrome and Buddhist temple. Adversely, cemetery, warehouse, court, Public Prosecutors' Office were poorly communicated. Highly communicative topographic map symbols should be developed on the basis of those cognitive characteristics.

    Design and Implementation of a Mobile Web Based Animated Map Service Using HTML5 Canvas and WMS Time Dimension

    Jae-Seong Ahn | 2011, 11(3) | pp.17~25 | number of Cited : 4
    This study implemented an interactive animated map service using HTML5 Canvas and WMS time dimension information. We can use the service without web browser plugins. Then the service supports multi platforms. We can get sequential map images using WMS time dimension information. We can isplay animated maps and control dynamic variables such as duration, display date, order using HTML5 Canvas. In conclusion, HTML5 Canvas and WMS fully support the functions to implement mobile web based interactive animated map service.

    Status of Geographic Name Management and Future Strategies in Korea

    Kyeong Park , Eunmi Chang | 2011, 11(3) | pp.27~34 | number of Cited : 1
    The geographical names are getting important, but the management agencies in Korean government are separated into NGII and KHOA. Errors and inappropriate expressions of geographic names are spreading out in the internet. Current status of internet maps including geographic names is reviewed and the main sources of errors are found. The roles for the management of geographical names in each organization are suggested. The strategies to fixing errors in geographical names are suggested with the list of action plans.

    Participatory and Collaborative Geovisualization in the Masten District Neighborhood Planning Process in Buffalo, New York: Making Geovisualization Together

    Jin-Kyu Jung | 2011, 11(3) | pp.35~51 | number of Cited : 1
    This research is intended to present a participatory and collaborative creation of geographic visualization, especially, in the community-based planning process. Responding to the recently emerging discussions of ‘the visual’ as more than mere “facts” in critical visual methodologies, geographic visualization, and participatory GIS, this study shows the expansion of the practice of geovisualization as a participatory and collective endeavor that actively includes local residents, and represents their shared ideas in the planning process. Geovisualization gives a critical consciousness to the locals to find, reflect, and construct their local knowledge, which had been often ignored in the traditional planning process. Local participants can see how their understandings of neighborhoods are prescribed, contextualized, conflicted, negotiated, and then visualized in various forms of eovisualization (e.g. neighborhood boundary maps with related photos). Examples from the Masten District Neighborhood Plan(MDNP) in Buffalo, New York demonstrate how the participatory and collaborative nature of geovisualization emerges throughout the planning process.

    The Roles of U.S. Census Bureau to the Development of GIS

    Kamyoung Kim , 최은영 | 2011, 11(3) | pp.53~68 | number of Cited : 4
    The purpose of this paper is to historically examine how the efforts of the Geography Division of U.S. Census Bureau to contribute to the development of geographic information systems (GIS). Through this, we want to establish the theoretical and logical bases about the role of GIS in making high quality census products. The influences of U.S. Census Bureau on the development of GIS are follows. First, they have set up and generalized the concept of topological structure in GIS database. Second, they have supported spatial analyses and spatial decision makings at the level of nation by constructing TIGER which is national-wide spatial database. Third, they have contributed to the popularization and universalization of GIS through distributing TIGER data for free.

    The Research on the Usage Analysis and Establishment of the Utilization Plan of the Long-term Weather Forecasts Service: The Case of Energy Industry

    Shin, Jungyeop , Lee, Gunhak , Choi Youngeun and 2 other persons | 2011, 11(3) | pp.69~87 | number of Cited : 2
    In the modern societies, the weather information of the weather services is becoming considered as important, and in recent years, more attention was paid to the long-term weather forecasts. The long-term weather forecasts is being serviced with the temperatures, precipitation in the perspective of nation, and based on the public information, the private sector is providing various kinds of long-term forecasts. This long-term forecasts is useful for the enhancement of the efficiency in the industry sector, and with this regard, the research is to establish the utilization plan of the long-term forecasts for the energy industry. The efficient utilization plan of the long-term forecasts for the energy industry was established based on actual demand research with the consideration of the utility, the applicability, the degree of the user-friendly, mission efficiency, and the phased utilization strategy was established. The purpose of the first phase is the public relations and enhancement of the awareness of the long-term forecast service, and that of the second phase is the organization for the service reinforcement of the long-term forecast service. The purpose of the third phase is the development and research of the tailored service of the long-term forecast, and that of the fourth is the high efficiency and utility maximization of the service. It is expected that this service utilization plan will revitalize the service of the long-term forecast in the energy industry and provide a useful framework for expanding the utility in other industry sectors.

    Developing a GIS-based Application System in Long Range Weather Forecasting : A prototype for Energy Industry

    Cho Daeheon , Shin, Jungyeop , LEE, SANG-IL and 2 other persons | 2011, 11(3) | pp.89~104 | number of Cited : 1
    Weather forecasts provide various industrial activities with essential information. This study aims to develop a GIS-based prototype application system of the long range weather forecasting which can be applied to the energy industry. As preliminary considerations, some implications of GIS in enhancing the usage of weather and climate information are discussed and a critical investigation on the current service system provided by the Korea Meteorological Administration is undertaken. Some conceptual cornerstones for a more advanced application system in terms of quality of information itself and its service are obtained with special focus on the case of energy industry. Based on these, a prototype, desktop GIS-based application system is developed for utilizing long range weather forecasting information. It is concluded that GIS could provide a highly effective and efficient platform in which various tasks pertaining to long range weather forecasting information, from data management to information service, are accomplished in an integrative way.

    Defining Class Intervals and Color Scheme of Choropleth Maps for the Production of 1981~2010 Korea Climate Atlas

    Choi Youngeun , Jeong, Jae Joon , 이재원 and 6 other persons | 2011, 11(3) | pp.105~112 | number of Cited : 7
    The purpose of this study was to define the class intervals and color scheme of choropleth maps for the publication 1981~2010 Korea climate atlas. The class intervals should be determined to represent properly the distribution and characteristics of climate elements considering characteristics of data such as their ranges(maximum and minimum). For the temperature regime, 23 classes were defined with the equal interval method while for the precipitation regime, 15 class were. The divergent color scheme was used for color scheme.The red color for the higher temperature classes and the blue one for the lower temperature classes have been selected. The green color has chosen for the greater precipitation classes while the brown one has for the lesser precipitation classes.
