Data Quality
A grid map of the mean groundwater level was produced from the interpolation of mean groundwater levels from 13 057 observation boreholes obtained from the SYKE-POVET database and groundwater level map data from the GTK-Lähde database using the Topo to Raster method in the Spatial Analyst module in ArcMap program. The depth to water grid map was produced from the subtraction between the topographic (DEM 10m grid data from NLS) and the groundwater level grid maps. The average depth to water grid map during the period 1971–2020 ranges between 0 and 14.5 m, with an average value of 4.5 m.
