# WISE GWB provisional dataset for horizon 3 - PUBLIC VERSION, Oct. 2012

The shape file GWB_horizon_h3 comprises all GWBs located in the groundwater body horizon 3, which are usually underlying the groundwater bodies assigned to horizon 2.
			
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/a631fb3b-d171-4924-a44c-6e80d49fdabf
