The dataset incorporating information about the surface geology of Finland is a seamless presentation of the surface geology depicting the distribution of both Quaternary and Pre-Quaternary deposits. Soil cover is omitted. The bedrock outcrops in the map of Superficial Geology at a scale of 1:1M are replaced by data from the Bedrock Map of Finland at a scale of 1:1M.

The map shows the heat flux density in mW / m2, which is mostly a reflection of the heat transfer from the Earth's interior to the surface; the heat flux is determined by measuring the temperature gradient in 111 wells and by measuring the thermal conductivity on rock samples from most of these wells; since the mentioned measurements refer only to the upper 3 to 5 km of the Earth's crust, they represent surface heat flux density. The map considers topographic correction and does not include significant con...

Likelihood of occurrence (below seafloor) of marine hydrates in the sediment column, and subsequently the likelihood of them being affected by dissociation processes resulting from natural or human-induced activities (liquefaction, explosions, collapse, crater-like depressions or submarine landslides).

The aquifer media layer is created by calculation of the slope value from the national topographic data. S values were classified into DRASTIC S values from 1-10. Due the generally flat topography, the majority of the catchment is assigned the higher ‘T’-values.

T layer represents topographical information, where calculation of the slope was effectuated and represented in rasterfile, reclassified into T index values.

T layer represents topographical information, where calculation of the slope was effectuated and represented in rasterfile, reclassified into T index values. The highest values correspond to low slope areas (alluvial aquifers) and the highest values correspond to steepest areas in mountains.
