DRASTIC parameter "S - Soil media" for Pilot area Tønder (Denmark)
This is the fourth parameter for the DRASTIC groundwater vulnerability assessment (Aller et al. 1987) applied at the HOVER WP7 pilot area Tønder (Denmark).
This geotiff is derived from Denmark’s digital surface geology map v.4 at 1:25.000 (GEUS) (Jakobsen et al., 2015). The sediment type at 1m depth is reclassified into the DRASTIC S-parameter classes. The map was then rasterized and gaps were filled with interpolation with a maximum search radius of five raster-cells.The pilot area takes the values between 3 and 10. See HOVER D7-2 for more details and references.
