  • This research focused on the effect of the GIS, uIT, and RS based smart disaster systems. Ubiquitous IT strongly involved in intelligent analysis for the natural disasters. Remote sensing technologies, such as hyper-spectral imaging, MODIS, LiDAR, Radar, and optical imaging processes, can contribute many means of investigation for the natural and unnatural problems in the atmosphere, hydrosphere, and lithosphere. Recent IT trends guides abundant smart solutions, such as automatic sensing using USN, RFID, and wireless communication devices. Smart monitoring systems using intelligent LBSs will produce many ways of checking, processes, and controls for the human safeties. In results, u-smart GIS, uIT, and RS based disaster systems must be using ubiquitous IT involved smart systems using intelligent GIS methods.

  • The purpose of this paper is to test the applicability of the rural amenity values assessment model(RAVAM) to a case study area. To verify the practical applicabilities of the RAVAM, south-east area of Kyounggi province was selected as a study area. Full data of 101 Myuns of Kyounggi province were gathered with Geographic In-formation System(GIS) and Remote Sensing(RS) techniques. All the 101 Myuns' rural amenity resources were assessed. Cluster analysis was performed on almost intact nature, interaction between nature and man, man-made amenity values to classify rural amenity characteristics. It was expected that the proposed RAVAM could be used in developing rural development plans considering local rural amenity resources' distribution.

  • 최근 수자원분야에서 원격탐사(RS) 및 지형정보시스템(GIS)의 비중이 높아짐에 따라 이를 이용하여 1,2 차원 수리분석 향상을 위한 활용이 증가하고 있다. 그러나 현재 사용하고 있는 일반적인 DEM은 하천부분에 대한 고도의 불일치로 인해 수리분석시 정밀한 분석을 하기에는 어려움이 따르므로 이에 대한 개선이 필요하다. 본 연구에서는 현재 사용하고 있는 USGS DEM과 낙동강 측량 자료를 이용하여 낙동강 유역 정밀 DEM 제작 방안을 제시하고자 한다. 측량자료를 이용하여 하천의 DEM을 생성한 후, 자체적으로 개발한 알고리즘을 이용하여 하천 DEM과 USGS DEM을 접합하여 낙동강 유역의 정밀 DEM을 제작한다. 이는 1,2차원 수리모델을 이용하여 분석할 때 결과를 더욱 향상시킬 것으로 기대한다.

  • Satellite and aerial remote sensing (RS) techniques have been provided to collect spatial data globally over the last few decades. However in developing countries such as China, there is still an urgent need for low cost and high resolution RS data. As an emerging RS platform, commercial Unmanned Aerial Vehicle (UAV) integrated with state-of-the-art sensors and information technologies has the potential to become a low cost tool to meet application demands. In this paper, the architecture of UAV RS operation system is mentioned. Moreover, key technologies in UAV RS system are analyzed and current work is reported.

  • This study aims to develop a potential evaluation method for urban spatial expansion using remote sensing (RS) and geographic information system (GIS). A multi-criteria evaluation method with several criteria and their weighting values was introduced to evaluate the score and quantification of the potential surface around the existing cities. The six criteria with one geographic factor, slope, and five accessibility factors, time distance from center of the city, national road, interchange of expressway, a big city, and station, were defined for the potential. RS techniques were applied for classification of the actual urban expansion maps between two periods, and GIS functions were used for score of accessibility criteria with a distance decay function from geographic, road and several point maps, which was developed in this study. The new methodology was applied to a test area, Suwon, between 1986 and 1996. In order to optimize the six weighting values, this study made new findings to search the optimal combination of the weighting values from new methodology, weighted scenario method for intensity order (WSM), combined with intensity order and AHP method, including a trial and error method for sensitivity analysis to make the intensity order. The optimal combination of the weighting values by the new method generated the optimal potential surface, considering spatial trend of urban expansion in the test area.

  • The need for recreation and green-tourism seems to be enhanced greatly according to increasing income and leisure. The rural area and village should be developed and improved with a new direction as basic areas for the green-tourism. This study developed a new methodology to be able to find suitable areas for recreation and green-tourism using GIS and RS. The eight criteria for suitability evaluation of recreation area extracted by GIS and RS techniques from computerized map layers and satellite images have their weighting values, which are quantified by AHP method. The new finding methodology was applied to a study area, the Ansung city in Kyunggi province. The results showed that the suitable area with high score for the recreation and green-tourism were analyzed spatially near by ancient culture and water resources. The new findings enable decision makers to analyze spatially the suitability area of the recreation area and village improvement for the green-tourism.

  • Remote sensing(RS)- and geographic information system(GIS)-based information management to measure and assess agri-environment schemes, and to quantify and map environment indicators for nature and land use, climate change, air, water and energy balance, waste and material flow is in high demand because it is very helpful in assisting decision making activities of farmers, government, researchers, and consumers. The versatility and ability of RS and GIS containing huge soil database to assess agricultural environment spatially and temporally at various spatial scales were investigated. Spectral and microwave observations were carried out to characterize crop variables and soil properties. Multiple sources RS data from ground sensors, airborne sensors, and also satellite sensors were collected and analyzed to extract features and land cover/use for soils, crops, and vegetation for support precision agriculture, soil/land suitability, soil property estimation, crop growth estimation, runoff potential estimation, irrigated and the estimation of flooded areas in paddy rice fields. RS and GIS play essential roles in a management and monitoring information system. Biosphere-atmosphere interection should also be further studied to improve synergistic modeling for environment and sustainability in agri-environment schemes.
