  • Recently the domestic technologies to manage forest and to control all related information were developed very rapidly by integrating FGIS (Forest Geographic Information System) and IT (Information technology). However, there still exists a mapping problem for example when overlaying a topography maps scaled in 1/5,000 to a forest type map scaled in 1/25.000. Moreover, there is a greater need to introduce the advanced spatial technologies such as high-resolution satellite image such as IKONOS and GIS to forest. In this study, 3D high-resolution forest mapping system was developed to possibly overlay with all kinds of scale maps and provide the all detailed information by using high-resolution satellite image and GIS. Through this system, all related forest officials could have and maintain the data consistency for their job and share the standard forest database with other post.

  • Facilities Management(FM) System is widely spread GIS applications introduced in local governments. Over the last few years many local governments in Korea have developed facilities management systems, especially for underground facilities(drinking water and sewerage) and road management systems. The concept of Standardized Facilities Management Software(SFMS) was developed to minimize the duplication of efforts in local governments. Recently local governments try to change their direction to Urban Information Systems(UIS) which can comprehensively manage their information project carried out by each sector. Therefore this study suggests a method for introducing a Standardized Facilities Management Software to help constructing urban information system. This method is expected to prevent double investment, reduce project time, minimize the risk of project failure, and activate information projects.

  • Solutions of many landscape problems depend on area-wide assessment and interpretation of spatial and physical characteristics over the study area. The authors argue that the public awareness for an area-wide urban landscape appears to be very low due to limited chance to the information. Acknowledging these constraints, an operational, user-friendly information system has been developed by combining internet technology with GIS. In particular, integration among satellite data and digital maps takes advantage of each component, and enables the landscape structure to be visualized, interacted with and deployed all on the Web. The 1m resolution IKONOS data realistically identified the major type of landscape by large scale spatial precision while TM data revealed successfully the major parameters that influence an area-wide spatial structure in the study area. This system would play a crucial role in improving the public awareness for area-wide landscape information if it is operationally introduced into the Government since the highly user-friendly interface based on image maps provides a completely new means for disseminating information for area-wide landscape in a visual and interactive manner to the general public.

  • In several years, the geographic information system has been being applied into various departments, i.e. estate, transportation, prevention against disasters, agriculture, environment, etc. Especially, it is very useful for us to manage the infrastructures of urban transit which are scattered and located in the vast areas of city. But, in the 2D geographic information system, it is impossible to manage the various inner facilities of stations which are in the same spatial location on GIS. Then, the 3D station management system has been developed for the efficient management of station facilities in urban transit. Through this system, from the virtual cyberspace of station on PC, we can move and go to any places of station we want without going to the station fields. So, we can manage the various information of location information, basis information, maintenance information about the inner facilities such as architectural structures, machinery facilities, electronic equipments. And, this system is also connected with the drawings and technical documents in each facilities. So, we're sure, this system will improve the efficiency of maintenance work and information management of stations.

  • The definition of urban forest is described as all forest and trees except the Natural Parks throughout whole territory in Urban Forest Act. But the concept of urban forest in the law differs from general awareness by Korean citizen and from definitions of other countries. For discussing such differences of urban forest definition, it was tested how much urban forest area would be changed according to the various definition of urban area. The urban area was defined to be four scenarios in this study in consideration of "urban area" by National Land Planning and Utilization Act (NLPUA), 300m buffered boundary from the "urban area" proposed by World Health Organization (WHO) and forest watershed area. In the scenario 1, including forest watershed intersected with "urban area" by NLPUA, urban forest area was estimated at 1.83 million ha in which urban forest area per person was 386㎡. In the scenario 2, including forest watershed intersected with 300m buffered boundary from the "urban area" by NLPUA, urban forest area was estimated at 1.92 million ha in which urban forest area per person was 405㎡. In the scenario 3, including forest watershed intersected with "urban area" placed within administration boundary (Eup·Dong districts), urban forest area was estimated at 1.08 million ha in which urban forest area per person was 230㎡. In the scenario 4, including forest watershed intersected with 300m buffered boundary from "urban area" placed within administration boundary, urban forest area was estimated at 1.20 million ha in which urban forest area per person was 256㎡. Therefore, the boundary of urban area should be agreed clearly prior to defining the urban forest area for avoiding unclear area calculated according to different definitions.

  • In this paper, a simplified visualization method is proposed for an urban space in consideration of weather and sun moving. In the proposed method, buildings and roads with shadows are visualized by the ray tracing algorithm. Also sky, snow, and rain are visualized by textures. Some textures such as snow and rain are generated in advance by the ray casting algorithm. Then we can obtain images with weather condition and shadows of sunlight by buildings along the road in relatively low computational cost

  • Urban planning is the task to explore measures for bringing order to the change in urban space of future predicted in relation to the size and purpose of the land and a variety of facilities in cities in order to present the environment that can promote the qualitative improvement of activities of residents, ensure orderly urban space of future, and create appropriate urban environment which meets the desire of citizens by anticipating the urban development on the basis of overall activities such as politics, economics, culture, etc, so that the improvement in urban life can be accomplished ultimately. Therefore, this study attempted to examine current conditions information necessary for establishing policies pursuant to the national land development plan and regional development, as well as respond to the needs of urban residents who need the improvement of settlement environment including various amenities for the convenience of life, by shifting away form the macroscopic and one-size-fits top-down approach of development so far and aiming a balanced development of national land in quest for welfare society and by utilizing the urban index as the basic prior task necessary for seeking the shift ind the direction of policies and setting the direction for policies on the basis of the top-down development approach which suits the anticipation and hope of local residents as the subject of development, considering the growing interest in the shift in the policies for regional development in this era of localization. Techniques for urban planning need to be applied, such as the prior planning and the following development, along with the support at the policy level for achieving the improvement in the related sector, in order to induce continuos urban deelopment based on the establishment of healthy and sound settlement environment, and furthermore, the efforts must be drven forward to improve the urban settlement environment while the urban planning and policies are established.

  • In an effort to prevent urban decline and hollowing-out phenomenon and to vitalize stagnant local economy, a new urban regeneration paradigm is on the rise. This study aims to analyze urban decline characteristics using the spatial statistical method and GIS on the basis of decline standards in the Urban Regeneration Special Act, and spatial autocorrelation technique. The Gwangju Metropolitan City was set as a research target, and the decline standards in the Urban Regeneration Special Act - population reduction, business declines, and outworn buildings - were applied as the indicator to secure the objectivity. In particular, this study has a distinctive feature from the other existing ones, as applying GIS and the spatial statistical technique, in a sense to make urban decline characteristics analysis by the spatial autocorrelation technique. The overall analysis procedure was carried out by applying the standards of designating urban regeneration regions, and following the spatial exploratory procedure step by step. Therefore, the spatial statistical method procedure and the urban decline characteristics analysis data being presented in this study, as the results, are expected to contribute to the urban decline diagnosis at the level of metropolitan city, as well as to provide useful information for spatial decision making in accordance with urban regeneration.

  • The purpose of this study was to investigate the citizens' perception of urban ecosystem and urban ecosystem education to find out how to plan and create an effective urban ecosystem and how to utilize urban ecosystem education and educational media according to age groups. To this end, an online survey of 416 Suwon citizens was conducted, and based on the responses of the respondents, cross-analysis, multiple-response analysis, and correlation analysis were conducted using the IBM SPSS Statistics Statistical Program. The study found that fewer respondents showed a high understanding of urban ecosystem concepts compared to those who recognized the importance of environmental issues. Nevertheless, most of the respondents were aware of the importance of preserving and protecting the urban ecosystem and responded positively to the inconvenience. In addition, most of the respondents were aware of the need for urban ecosystem education and were found to have different preferred information media depending on age. It has been confirmed that the establishment of facilities such as ecological learning centers and seasonal environmental schools is the top priority among all age groups. Citizens are also aware of the importance of preserving and protecting the urban ecosystem and the need for education, but it is deemed necessary to supplement it because effective urban ecosystem conservation and protection plans and systematic education are not provided that citizens can sympathize with. In addition, it is deemed that various measures should be presented in selecting responsible organizations and educational media that host the education for effective education and promotion of urban ecosystem education according to conduct urban ecosystem education.
