The DRASTIC index according to Aller et al. (1987) is constituated as a weighted linear sum of seven environmental parameters (Depth to water table, Net recharge, Aquifer media, Soil media, Topography/slope, Impact of vadose zone media, Hydraulic conductivity) with parameter classes scored from 1..10 for their specific impact on groundwater pollution potential. The five classes are derived from equal interval slicing of the continuous DRASTIC index Federal Institute for Geosciences and Natural Resources (BGR) Stilleweg 2 Hanover 30655 Germany Andreas.Guenther@bgr.de originator Geology GEMET - INSPIRE themes, version 1.0 2008-06-01 publication European Spatial scope 2019-05-22 publication HOVER European Geoscience Registry - Projects 2020-01-01 publication Groundwater, pollution potential, aquifer, Europe, DRASTIC, EGDI otherRestrictions Copyright (All Rigths Reserved) otherRestrictions no limitations to public access grid eng geoscientificInformation -24.591 71.467 30.355 71.201 TIFF GeoTIFF https://maps.europe-geology.eu/?mapname=egdi_geoera_hover#baslay=baseMapGEUS&extent=-33340,973700,8538320,5491680&layers=gewp7_peu0_drastic WWW:LINK-1.0-http--link EGDI platform information Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 See referenced specification DRASTIC calculation and parameter scoring was done with SAGA GIS 7.7.1 software.The DRASTIC classes 1 - 5 are provided as 4 byte floating point numbers in .tif format
