[학술논문] 수문인자추출에서의 SRTM DEM (Shuttle Radar Topography Mission Digital Elevation Model) 적용성 평가: 대동강 및 금강 지역 사례연구
...manipulation into analysis outputs. Sensitivity of hydrologicanalysis to the errors has not been fully understood yet. This study investigated their impact on estimation of hydrologic derivativessuch as slope, stream network, and watershed boundary using Monte Carlo simulation and spatial moving average techniques. Differentamount of the errors and their spatial auto-correlation structure were considered...

[학술논문] 남북한 관개체계 및 농업용 흙수로의 규격 비교 연구
...of irrigation systems, earthen canal structures, and operational frameworks in both Koreas, focusing on differences in canal design standards, slope ratios, and lining methods. South Korea utilizes standardized guidelines, concrete-lined canals, and slope stability analysis, while North Korea relies on gravity-flow earthen canals adapted to topography and limited resources. Key findings highlight...

[학술논문] Landslide Susceptibility Analysis in Baekdu Mountain Area Using ANN and AHP Method
...software through weighted overlay GIS (Geographic Information System) method in this paper. To assess the landslide susceptibility, five factors which affect the landslide occurrence were selected as: slope, aspect, soil type, geological type, and land use. The weight value and rating value of each factor were calculated by the two different methods of AHP (Analytic Hierarchy Process) and ANN (Artificial...

[학술논문] RapidEye 위성영상의 시계열 NDVI 및 객체기반 분류를 이용한 북한 재령군의 논벼 재배지역 추출 기법 연구
...extraction classified into 6 categories using unsupervised classification by clustering analysis. Finally, the unsuitable paddy field area were assorted from the topographic factors such as elevation and slope. As the results, about 33.6 % of the total area (32313.1 ha) were classified to the paddy field (10847.9 ha) and 851.0 ha was classified to the unsuitable paddy field based on the topographic factors...

[학술논문] 북한의 산림복원계획과 기준 경사도 고찰
...mountains with slope greater than 20°, however, at present, the「Marginal Cropping Land Policy」recommends cropping lands with slope bigger than 8.5° to forest land. In 1961, in「Land Reclamation of One Million Hectare」, North Korea reclaimed additional cropping lands with slope bigger than 8.5°, and currently, the「Act on Forestry」states to enforce reforestation with slope bigger than 20°...
