Summary of Dataset | This dataset is a reprocessed result of the 4th General Survey on National Inland Wetlands (2016-2020). It compares areas defined by the Wetlands Conservation Act, such as lakes, ponds, swamps, rivers, and estuaries, using the Continuous numerical topographic map (2020) and V-world map (2021-2022). The dataset shows the boundaries and attributes of South Korea’s inland wetlands based on artificial structures like embankments, channels, weirs, and dams. The data is in Geopackage (*.gpkg) format, with the coordinate system KGD2022/Central Belt 2010 and encoding UTF-8 | |
