# WISE GWB provisional dataset for horizon 2 - PUBLIC VERSION, Oct. 2012

The shape file GWB_horizon_h2 comprises all GWBs located in the groundwater body horizon 2. Depending on the applied method these Ground Water Bodies are either underlying the uppermost groundwater body horizon 1 or form the uppermost groundwater body resources in many parts of a MS.
			
The dbf tables of the shape files include the columns “EU_CD_GW” as the GWB identifier and “Horizon” describing the vertical positioning. The polygon identifier “Polygon_ID” was added subsequently, because some GWBs consist of several polygons with identical “EU_CD_GW”even in the same horizon.
Some further GWB characteristics are provided with the Microsoft Excel file “GWB_attributes_2012June.xls” including the column “EU_CD_GW”, which serves as a key for joining spatial and attribute data. There is no corresponding spatial data for GWBs in the Microsoft Excel table without an entry in column “EU_CD_GW”.

The spatial resolution is given for about a half of the GWBs in the column “Scale” of the xls file, which is varying between the MS from 1:10,000 to 1:1,000,000 and mostly in the range from 1:50,000 to 1:250,000.https://sdi.eea.europa.eu/geonetwork/srv/api/records/f5f3fd1a-d62b-4cfc-a769-fa1acfd08d1f
