The WFS download service of the Shallow Geothermal Energy Potential Maps database contains the following information layers collected and produced within the framework of the Shallow Geothermal Energy Pottential Maps project:

• 13 area-specific GIS information layers:

o thermal conductivity maps λ [W/m*K] at depths of 40, 70, 100 and 130 m below ground level;

o unit heat output maps qv [W/m] for 1800 h of heat pump operation per year at depths of 40, 70, 100 and 130 m below ground level;

o unit heat output maps qv [W/m] for 2100 h of heat pump operation per year at a depth of 40, 70, 100 and 130 m below ground level;

o Borehole heat exchangers feasibility map according to environmental conditions.

• layers made on the basis of the data contained in the documentation in the Central Geological Archives of Polish Geological Institute:

o Location of boreholes for ground source heat exchangers (GHE),

o representative profile of the borehole for ground source heat exchanger (GHE) with borehole documentation card,

o objects with ground source heat pumps (GHP) installed,

o the area of location of an object with a shallowe geothermal installation;

• a layer created by analyzing boreholes from the Central Hydrogeological Databank in accordance with the 2013 PORT PC guidelines: thermal conductivity λ [W/m*K] to a depth of 100 m below ground level;

• polygon layer with mapped areas;

• polygon layer with a map grid with completed maps at a scale of 1:10 000;

• polygon layer with a map grid with completed maps (or under development) at a scale of 1:50 000.
