This map shows the sediments close to the surface (or sea bottom), down to a depth of about 5 meters. This map is based on existing maps of the former Rijks Geologische Dienst and, where necessary, supplemented by unpublished data. The sediments are classified according to the new lithostratigraphical legend used by TNO since 1997. This classification is based on lithological and seismological properties, and on stratigraphic position and origin.The age of the sediments is not taken into account in this cl...
This digital soil map shows the geology 1 meter below surface, just beneath ploughing- and culture layers. The map is digitized from redrafted maps originating from fieldwork, where soil samples are collected using a charting spear in a 100 m grid throughout the country. This map is a result of systematic geological mapping, and is an ongoing effort.This version 4.0 from 2015 classifies 88 % of Denmark's area. The legend shows 82 different soil types. The map is used for research, in relation to environme...
The dataset has been created by combining, generalizing and vectorizing information from maps of bedrock and Quaternary sediments of at 1:200 000 and 1:50 000 scales. The areas depicted on the map correspond in age, genetic type and lithological composition to the sediments and rocks lying directly under the topsoil layer. In other words, the map shows the distribution and composition of Quaternary sediments, including small alvar areas with bedrock outcrops.
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.
