    Applying a Geoinfographics Approach to Policy Support Mapping

    Myung-Hwa Hwang | EunSun Im | 전성제 and 1other persons | 2016, 16(3) | pp.1~14 | number of Cited : 2
    Recently many of Korean governments and public institutions have strived to implement policy support mapping to enable evidence-based policy making. To date, policy support mapping has proved useful in providing basic administrative data and objective evidence for decision making to policy practitioners. It, however, has not played an active role in policy communication since ordinary people without any knowledge of map reading often have difficulties with understanding policy information contained in maps. To enhance the communicative capacity of policy support mapping, this study proposes a geoinfographics approach that integrates location-based data with advanced methods for visual communication such as geovisualization, infographics, and storytelling. In the study, the concept and development framework of geoinfographics are defined and applied to the production of three examples. The results indicate that the proposed approach would be useful for sharing information of current states of regional development and important policy issues identified from policy support mapping. They also suggest that effective geoinfographics can be created through delicate planning of information communication and that visual representations and interactive techniques should be chosen with careful consideration to user characteristics.

    Analysis on the Changing Spatial Patterns of National Assembly Election Results: Focusing on 19th and 20th Elections

    Soyoung Lee | Cho Daeheon | Changwoo Jeon and 1other persons | 2016, 16(3) | pp.29~47 | number of Cited : 4
    Election is one of important interests in geography because the members of National Assembly of Korea are elected mainly in spatial unit, which is called Election District. The purpose of this study is to understand the changing spatial pattern between the 19th and the 20th National Assembly Elections in South Korea. For this purpose, spatial statistical analysis was performed to explain the results of the elections in Eup-Myeon-Dong units through out the Capital Region and the study offers three primary findings. First, in general, the voting rate for ruling party decreased in both Local District Election and Proportional Representation Election, which comprise the National Assembly Election. However, considering only two main parties, the total vote rate of the ruling party, and the number and the vote rate in Eup-Myeon-Dong units where the percentage of votes for the ruling party is the highest, did not have significant change. Second, the results of the spatial cluster analysis indicated a strong pattern of spatial clustering in the Eup-Myeon-Dong units than that of election district units. Similarly, the proportional representation election outcomes showed a stronger spatial clustering than those in the local district election. Third, according to the results of bivariate spatial association analysis between two periods, 30% of Eup-Myeon-Dong units are found to adhere to the prior political inclination, while the regions with change in vote rate of the ruling party also showed a strong pattern of spatial clustering.

    Geunhan Kim | Kim, Oh Seok | 정휘철 | 2016, 16(3) | pp.49~61 | number of Cited : 6
    To establish a national comprehensive development planning of Korean Peninsula that harmonizes both environment and development, the environmental spatial information is necessary to be used for environmental planning. However, the spatial information of North Korea is absent. Although the Ministry of Environment of the Republic of Korea possesses the land cover map with level 1 classification, this map only has seven classes and low spatial resolutions, resulting in a limited availability for decision makings. Therefore, this study finds out that a newly created land cover map through applying remote sensing technology for inaccessible terrain is suitable for environmental spatial information in North Korea. Also, the research aims to create land cover map with level 2 classification which can be used for a variety of fields since it has higher resolutions and categorization criteria of attributes is more accurate than existing land cover map with level 1 classification. In order to do that, this study examines existing land cover maps in the field of environment, urban, forest, and agriculture. Based on classification structures in these fields, possibility and availability of establishing land cover map with level 1 classification is considered. With these considerations, we change the existing 22 classification structures which are used in land cover map with level 2 classifications by the Ministry of Environment into 16 classification structures and establishment methods for each classification structure are suggested. Also, Kaesong area is chosen for project area and establishment methodologies for each classification structure are developed. The results of demonstration establishment of land cover map in North Korea show that the entire classification accuracy is 95.35% which is appropriate to establish land cover map with level 2 classification in North Korea.

    Identifying the Spatial Clusters of Subregions with High-risk of FMD Occurrence Using Local Spatial Statistic

    Pak Son Il | Gyoungju Lee | 2016, 16(3) | pp.63~73 | number of Cited : 1
    Foot-and-mouth disease(FMD), one of the first class infectious diseases in domestic animals, has caused tremendous socioeconomic costs due to the preventive measures, compelled to be taken by law, such as culling, banning on vehicle movements, etc. FMD, once occurred, is concerned to spread quite rapidly and thus, preemptive efforts need to be made to prevent the outbreak, along with on-site struggling against epidemics. To this end, mid- and long-term plan for preventing and controlling epidemic need to be presented. Since available resources for preventing and controlling efforts are limited, it is important to identify local areas requiring a priority in concentrating the resources and a relevant strategic management. Those areas point to the geographic locality with potentially high risk of FMD occurrence. The objective of the study is to identify the local areas with potentially high risk of FMD outbreak using a local spatial statistic in an exploratory manner. To this end, the Score statistic is used. Based on the statistic, an empirical analysis was made for the data containing the information on FMD occurred during the period of December 2014 to April 2015. Analysis results show marked spatial clusters of FMD. Additionally, policy implications associated with prevention and control activities were discussed in mid- and long-term perspective.

    Mapping the Assessment of Natural Environment Outstanding Areas of North Korea Using Logistic Regression Analysis

    Geunhan Kim | Eun Jung Lee | 정휘철 and 1other persons | 2016, 16(3) | pp.75~88 | number of Cited : 10
    Environmental planning based national land planning is essential as a means of conservation of national land and the prevention of destructing the natural environment from rapid national land development, especially after the unification. For such national land planning, objective natural environment assessment of North Korea’s territory should be prepared. Therefore in this study, a methodology to assess natural environmental outstanding areas of North Korea was suggested. 30 indicators were selected and were used to assess the natural environment outstanding areas using logistic regression analysis. As a result, the probability map of natural environment outstanding areas and the ROC analysis showed accuracy of 89.4% and 96.1%, respectively. For the verification of accuracy, the result of the study showed high conformity with the Environmental Conservation Value Assessment Map (ECVAM), and was able to conclude that the top 40% values from the assessment can be classified as natural environment core areas and top 60% values be classified as natural environment buffer areas.

    Spatial Socio-environmental Analysis of Tuberculosis in South Korea Using Eigenvector Spatial Filtering Methodology

    Changmin Im | Youngho Kim | 2016, 16(3) | pp.89~101 | number of Cited : 5
    In South Korea, tuberculosis (TB) is considered as a terminated disease long before. However, incidence and fatality rate of TB in South Korea still have been ranked No.1 among OECD nations being a serious medical and social problem. Especially, TB is a social disease with its incidence influenced by socio-environmental determinants. Naturally, many current analyses on TB in the world try to combine bio-medical and socio-environmental determinants simultaneously. However, it should be noticed that most TB studies in South Korea only focused on bio-medical perspectives. Therefore, this study analyzes TB in socio-evironmental perspectives. In particular, this study applies Eigenvector spatial filtering methods accounting for spatial patterns of TB in South Korea.

    An Analysis of Business Model of Open Source GIS Software and Activation Strategy for Korean Open Source GIS Software Companies

    Youngok Kang | Son, Serin | 2016, 16(3) | pp.103~113 | number of Cited : 5
    In recent years Open Source GIS software had been introduced in various areas, as its interest and application continue to increase worldwide. In the same token, the interest and application of Open Source GIS software also keep expanding in diverse fields not only in the world and but also in Korea. However, in Korea, there are only a few companies related to Open Source GIS software among the companies that run geospatial information related business. In addition, it is very weak in the development of business model which applies Open Source to actual fields in Korea. In this study we are going to investigate what kinds of business models are feasible in geospatial information related business in Korea and then to analyze how domestic GIS software companies have applied the Open Source to their business, after performing the preceding researches of business model for Open Source software. We think that this study is very valuable not only to vitalize the ecosystem of Open Source GIS software industry in Korea, but also to initiate new businesses of domestic GIS software companies.

    Kim, Oh Seok | 한기주 | Kirl Kim | 2016, 16(3) | pp.115~127 | number of Cited : 4
    Climate change caused by global warming is an important environmental problem that all around the world has experienced. Korea has set up the adaptation plan at the level of central and local governments to promote the climate change adaptation capacity. However, a standardized system that monitors and evaluates the performance of climate change adaptation capacity by local governments has not been equipped well until now. The purpose of this study is to construct the quantitative variables and evaluate the climate change adaptation capacity by the sixteen local governments except for the city of Sejong through an index analysis. The 8 of sectors (namely, health, agriculture, forest, water management, ecosystem, marine product industry, disaster, and adaptation infrastructure) and the 113 of variables that can measure the climate change adaptation capacity were selected, and the results of the index analysis were elicited through categorical scales. Some governments with a high level of climate change adaptation should maintain their continuous plans and the others with a low level of it should take an effort to catch up with the good example of local governments. The measures and indices elicited in this study will become a milestone that monitors and evaluates the adaptation measures to climate change at the level of Korean local governments in the near future.

    Construction of GIS Database for Wildfire in the Korean Peninsula Using MODIS Data

    Soo-Jin Lee | Myoungsoo Won | Keunchang Jang and 4other persons | 2016, 16(3) | pp.129~137 | number of Cited : 3
    Abstract PDF
    In response to recent climate change, the occurrences of large-scale wildfire are increasing around the world, and the wildfires in South Korea also tends to increase as well. Recently, many wildfires which occurred in North Korea have spread to the territory of South Korea including the demilitarized zone. The records of past wildfire occurrences can be retrieved by using an open API (application programming interface), but only domestic wildfire cases are provided because they are collected by administrative agencies. For this reason, we built a GIS database of daily wildfire occurrences by reprocessing MODIS (Moderate Resolution Imaging Spectroradiometer) data for the period of 2000-2015 in order to create long-term time-series wildfire dataset of the Korean Peninsula including North Korea. We used MOD14A1/MYD14A1 products of Terra/Aqua satellites for extracting wildfire information such as occurrence location, reliability of detection, and fire radiative power, which were written in the Shapefile format. Our GIS database can be utilized by other researchers to analyze the spatio-temporal characteristics of wildfire in the Korean Peninsula, so the data files are provided on the web for free download.
