 Abstract

- In addition to a total of 20 types of topography/moisture analysis maps that have already been built using a digital topographic model (DEM), in this study, a total of 32 types including 26 types of topographic analysis diagrams and 6 types of hydrological analysis diagrams were performed through various topography/hydraulic analysis. Additional species were built. As with the existing established data, the construction range is the whole of South Korea, the resolution is 30 m, and the coordinate system is UTM-K coordinates. The constructed data format is provided in three formats: ASCII, ARCGIS GRID, and GEOTIFF. All these topographic / hydrological analysis data can be downloaded free of charge from the Environmental Big Data Platform (www.bigdata-environment.kr).
