 Abstract
 PDF
- Groundwater pollution vulnerability was mapped for entire South Korea using groundwater, topography, geology, and soil data. For this, the DRASTIC model developed by the US Environmental Protection Agency was used and the geographic information system (GIS) was used as the basic tool. This groundwater pollution vulnerability map can be usefully used as basic data for groundwater development and conservation management. The constructed data is provided as entire South Korean and regional data, respectively. In addition, in order to expand the accessibility of the data, it is converted and provided in three data formats: ASCII, ArcGIS Grid, and GeoTIFF. All these satellite image analysis data can be downloaded free of charge from the Environment Big Data Platform website (www.bigdata-environment.kr).

Abstract
PDF
- In this study, 17 types of satellite analysis maps were generated using Landsat-8 and Sentinel-2 satellite images acquired at 2019 and 2020. Totally, 68 of satellite analysis data were produced. The scope of deployment is South Korea as a whole, with a resolution of 30 meters, and the coordinate system is UTM-K coordinates. The established data will be provided in both South Korean and regional data respectively. In addition, it is provided by three data format: ASCII, ArcGIS Grid, and GeoTIFF for enhancing accessibility of the data. All these satellite analysis data can be downloaded free of charge from the Environmental Big Data website (www.bigdata-environment.kr), an environmental business big data platform.
