  • As the geographical information changes continuously, it has been difficult to manage it in consistent manner. Especially different terminologies are often used for describing the same object. These characteristics of geographical information make the information search be very unproductive. Recently, it is widely recognized that capturing more knowledge is the next step to overcome the current difficulties on sharing geographical information. In this paper, we utilize the ontology concept in order to facilitate information search for geographical data in the internet environment. A prototype of search system implemented using the ontology for river-related data is presented.

  • Due to the development of information technology and business related to geographical location of customer, the need for the storage and analysis of geographical location data is increasing rapidly. Geographical location data have a spatio-temporal nature which is different from typical business data. Therefore, different methods of data storage and analysis are required. This paper proposes a multi-dimensional data model and data visualization to analyze geographical location data efficiently and effectively. Purchase order data of an online farm products brokerage business was used to build prototype datamart. RFM scores are calculated to classify customers and geocoding technology is applied to display information on maps, thereby to enhance data visualization.

  • In this Paper, we Propose web-based Media GIS architecture using 3D geographical database and GPS-related data resulted from 45-Van. We introduce a novel interoperable geographical data service concept; so-called, Virtual World Mapping (VWM) that can map 3D graphic world with real-world video. Our proposed method can easily retrieve geographical information and attributes to reconstruct 3D virtual space according to certain frame in video sequences. Our proposed system architecture also has an advantage that can provide geographical information service with video stream without any image processing procedures. In addition to, describing the details of our components, we present a Media GIS web service system by using GeoVideoServer, which performs VWM technique.

  • The need and concern about ecosystem are growing rapidly. However, ecosystem management systems are still in the first stage since the data are handled locally and separately. It results in the waste of money and time. In this research, we designed and implemented ecosystem management system of stream region using geographical information system(GIS) that is able to be used to manage the natural resource efficiently. It is expected to be used as a useful tool for Improvement of environment and management of ecosystem as well as recovery of natural environment.

  • The purpose of this study is to identify the problems of the present status of the Jeollanamdo's geographical name task by analyzing it and to suggest ways to improve it. For this purpose, the theoretical review including the definition of the geographical name as the subject of the study is conducted. Also, by analyzing the current structure of geographical name, the enactment and improvement of the ordinance of the committee on geographical name, and the management of committee on geographical name etc, the problems of the geographical name task are derived and suggestions for improvement are proposed. The results of this study are as follows: First, as a plan to improve the professionalism of the organization and the officer in charge of the geographical name task, this study suggests the unification of the department in charge of geographical name task, the specialization of the official in charge, and the development of training and teaching materials related to the geographic name task. Secondly, in order to improve the ordinance and the management of the committee on geographical name, this study suggests the enactment and improvement of the ordinance of committee on geographical name, the guidance and the supervision of the establishment and operation of the committee on geographic name, the simplification of procedures of establishing and changing geographical name, and enactment of geographic name a Law.

  • This study describes a methodology to develop a environmental and geographical information system for managing a national scale which is supports the environmental fate modeling. This system was developed via the integration of environmental and geographical information database(DB) and the DB usage software. For the sound environmental management, the DB were constructed by extracting the geometrical figures-such as points, polylines, and/or polygons-based on the geographical information previously developed in Korea. Then it was connected with the environmental information. Based on the Visual Basic Complier, the software can be a useful tool for visualizing the DB, for searching the environmental & geographical information, and supporting the environmental fate modeling.

  • The purposes of this paper are to examine the mechanism of the new economic spaces and to suggest directions of geographical research in the knowledge-based information society. It introduces the background of the formation of the new economic spaces and examines network, embeddedness, and agglomeration and dispersion as mechanisms of the new economic spaces. Based on the result of case studies of Kangnam area, the most active innovation region in Korea, and of Sunchang, one of the backward regions in Korea, the paper points out that new economic spaces are now developing even in the peripheral areas. Considering the result of theoretical discussions and case studies, the paper suggests three directions for future geographical research such as research from a integrative viewpoint, development of new methodologies of geographical research, and policy directed research in geography.

  • Marine geographical names refer to the names for the geographical forms in nature such as oceans, straits, bays, inlets, and channels as well as the various undersea form including reefs and trenches. Marine geographical forms, lying under the sea, are different from those in land and are related directly and indirectly to the safe navigation of ships, that is, property and life of human beings. Marine geographical names have not been correctly named and used so far as in the case of using the name 'Sea of Japan' instead of 'East Sea' Marine geographical names have been created arbitrarily from various sources including researchers, institutes, and academic societies, which leads to confusion and makes it difficult for those to be acknowledged internationally. This paper examines the uniqueness and technicality of marine geographical names and analyzes the efforts and status for the standardization processes in Korea.
