The social and economic harm to North Korea caused by water-related disasters is increasing with the increase in the disasters worldwide. Despite the improvement of inter-Korean relations in recent years, the issue of water-related disasters, which can directly affect the lives of people, has not been discussed. With consideration of inter-Korean relations, a government-wide technical plan should be established to reduce the damage caused by water-related disasters. Therefore, the purpose of this study was to identify remote sensing and GIS techniques that could be useful in reducing the damage caused by water-related disasters while considering inter-Korean relations and the disasters that occur in North Korea. To this end, based on the definitions of disasters in South and North Korea, water-related disasters that occurred during a 17-year period from 2001 to 2017 in North Korea were first summarized and reclassified into six types: typhoons, downpours, floods, landslides, heavy snowfalls, and droughts. In addition, remote sensing- and GIS-based techniques in South Korea that could be applied to water-related disasters in North Korea were investigated and reclassified according to applicability to the six disaster types. The results showed that remote sensing and other monitoring techniques using spatial information, GIS-based database construction, and integrated water-related disaster management have high priorities. Especially, the use of radar images, such as C band images, has proven essential. Moreover, case studies were analyzed within remote sensing- and GIS-based techniques that could be applicable to the water-related disasters that occur frequently in North Korea. Water disaster satellites with high-resolution C band synthetic aperture radar are scheduled to be launched by South Korea. These results provide basic data to support techniques and establish countermeasures to reduce the damage from water-related disasters in North Korea in the medium to long term.

朝韩合作遥感与地理空间信息技术减少与水有关的灾害损失的优先性分析

与水有关的灾害对朝鲜的社会和经济危害随着世界范围内灾害的增加而增加。尽管近年来朝韩关系有所改善，但与水有关的灾害直接影响人们生活的问题尚未得到讨论。考虑到朝韩关系，应制定一项全政府范围的技术计划，以减少与水有关的灾害造成的破坏。因此，本研究的目的是在考虑朝韩关系和朝鲜发生的灾害的同时，确定有助于减少与水有关的灾害造成的损害的遥感和GIS技术。为此，根据南北朝鲜灾难的定义，首先总结了从2001年到2017年这17年间朝鲜发生的与水有关的灾害，并将其重新分类为六种类型：台风，倾盆大雨，洪水，山体滑坡，大雪和干旱。此外，根据在六种灾害类型上的适用性，对可用于朝鲜与水有关的灾害的韩国基于遥感和GIS的技术进行了调查和重新分类。结果表明，利用空间信息的遥感和其他监视技术，基于GIS的数据库构建以及与水有关的综合灾害管理具有很高的优先级。特别是，已证明必须使用雷达图像（例如C波段图像）。此外，在基于遥感和基于GIS的技术中对案例研究进行了分析，这些技术可能适用于朝鲜频繁发生的与水有关的灾害。预定由韩国发射带有高分辨率C波段合成孔径雷达的水灾卫星。这些结果为中长期减轻北朝鲜与水有关的灾害造成的破坏提供了支持技术的基础数据并制定了应对措施。
