  • The ultimate goal of satellite development is to use information obtained from satellites. Therefore, national-levelsatellite development program should include not only hardware development, but also infrastructure establishment and application technology development for information utilization. Until now, Korea has developed various satellites and has been very useful in weather and maritime surveillance as well as various disasters. In particular, KOMPSAT (Korea Multi-purpose Satellite) images have been used extensively in agriculture, forestry and marine fields based on high spatial resolution, and has been widely used in research related to precision mapping and change detection. This special issue aims to introduce a variety of recent studies conducted using KOMPSAT optical and SAR (Synthetic Aperture Radar) images and to disseminate related satellite image application technologies to the public sector.

  • As global warming has caused the number of abnormal changes in climate to increase throughout the world, much damage has occurred recently in Korean Peninsula which results from unexpected heavy rains, landslides, and floods from typhoons. To prevent and cope with these annually repeated natural hazards, the overall improvements are needed, including systematic management of the existing natural hazard information and improvement of hazard information. In this study, multi-purpose hazard information map based on digital image was constructed as an effective way to enhance hazard management considering regional characteristics and hazard response capabilities in the field. Multi-purpose hazard information map with a new concept by fusion of geospatial information and hazard attribute information is able to support quick decision for hazard management making and development of hazard information system.

  • 도시라는 광역지역의 확장을 분석하는데 위성자료는 매우 유용한 정보를 제공한다. 특히 한국항공우주연구원에서 운용중인 다목적 실용위성(KOMPSAT) 1호 영상자료는 해상도가 높아 도시지역의 분석에 유용한 정보를 제공하고 있으며, 과거의 항공사진 등을 복합적으로 활용한다면 도시의 확장 과정에 대한 시계열 분석이 가능하다. 도시의 확장 과정을 분석하여 그 정보를 추출하는 것은 새로운 도시계획을 위한 필수적인 기본 자료를 구축하는 중요한 역할을 할 수 있으며, 특히 2003년 개정 시행중인 국토의 계획 및 이용에 관한 법률은 도시기본계획 수립에 있어 도시의 성장 경향 등에 관한 기초조사를 의무화한 토지적성평가 제도를 도입하고 있다. 본 연구에서는 다목적 실용위성 1호 EOC 영상과 기타 원격탐사 자료를 복합적으로 활용하여 대전광역시 도시화 지역의 확장 추이를 분석하고 그 경향과 특성을 도출해 도시계획 수립에 원격탐사 자료를 활용할 수 있는 가능성을 제시해 보고자 한다.

  • Following the successful launch of KOMPSAT-3 in May 2012, KOMPSAT-5 in August 2013, and KOMPSAT-3A in March 2015 have succeeded in launching the integrated operation of optical, radar and thermal infrared sensors in Korea. We have established a foundation to utilize the characteristics of each sensors. In order to overcome limitations in the range of application and accuracy of the application of a single sensor, multi-sensor image fusion techniques have been developed which take advantage of multiple sensors and complement each other. In this paper, we introduce the development of software (InFusion) for multi-sensor image fusion and valued-added product generation using KOMPSAT series. First, we describe the characteristics of each sensor and the necessity of fusion software development, and describe the entire development process. It aims to increase the data utilization of KOMPSAT series and to inform the superiority of domestic software through creation of high value-added products.

  • Recently, the development of multi-purpose tunnel that has functions of roads and waterways has been attention for efficient utilization of underground space. However, there is no study on the multi-functional tunnels behavior for the convert of iterative function and change of water pressure. In this study, the vulnerable section was analyzed due to repeated functional change. A basic review was implemented for the operation of the multi-purpose double-deck tunnel. Also, the vulnerable section for convert of iterative function of multi-functional tunnel has been analyzed by simulation. Management of multi-functional tunnel should considered in various analyzed and some problems. The criteria for management of multi-functional tunnels is proposed.

  • This paper proposes a novel two-tier optimization approach for decision making in many-objective problems. Because the Pareto-optimal solution ratio increases exponentially with an increasing number of objectives, simply finding the Pareto-optimal solutions is not sufficient for decision making in many-objective problems. In other words, it is necessary to discriminate the more preferable solutions from the other solutions. In the proposed approach, user preference-oriented as well as diverse Pareto-optimal solutions can be obtained as candidate solutions by introducing an additional tier of optimization. The second tier of optimization employs the corresponding secondary objectives, global evaluation and crowding distance, which were proposed in previous works, to represent the users preference to a solution and the crowdedness around a solution, respectively. To demonstrate the effectiveness of the proposed approach, decision making for some benchmark functions is conducted, and the outcomes with and without the proposed approach are compared. The experimental results demonstrate that the decisions are successfully made with consideration of the users preference through the proposed approach.
