초록

북한 댐에 대한 정보는 NASA, FAO, ICOLD 등에서 제공하고 있는 글로벌 정보에서 확인이 가능하다. 그러나 대부분의 댐 정보가 1980년대 이전의 댐 정보로서 정보의 시의성이 부족하다. 북한은 2010년대 이후 약 30여 곳에 댐을 건설한 것으로 확인되고 있다. 본 연구에서는 Sentinel-1 위성영상 분석을 통해 북한의 댐 위치도를 구축하는 것을 목적으로 하였다. Sentinel-1 영상분석을 통해 수체면적을 추출하였고 Google Earth와의 중첩을 통해 댐의 위치정보를 구축하였다. 북한 댐 523곳의 위치정보를 구축하였고, 이 중에서 댐 배후면 수체면적이 1.0km2 이상인 곳이 110곳으로 분석되었다. 본 연구에서 구축한 댐 정보는 위치정보만을 포함하고 있어 향후 댐명, 댐 제원 등에 대한 속성정보의 구축은 추가로 필요하다.

Information on North Korean dams can be found in global information provided by NASA, FAO, and ICOLD. However, most of the dam information is before the 1980s and the timeliness of the information is insufficient. It has been confirmed that North Korea has built dams in about 30 places since the 2010s. In this study, the purpose of constructing a map of the location of a dam in North Korea through Sentinel-1 satellite image analysis. The water surface area was extracted through Sentinel-1 image analysis and the location information of the dam was constructed through overlapping with Google Earth. Location information of 523 North Korea dams was established, of which 110 had a water surface area of 1.0 km2 or more behind the dam. Since the dam information constructed in this study includes only location information, it is necessary to establish additional attribute information on the dam name and dam specifications in the future.
