Thermal Conductivity down to 60 mWärmeleitfähigkeit bis 60 m
Wärmeleitfähigkeit bis 60 mThermal Conductivity down to 60 m
This WFS API from LGV Hamburg (Geological Survey) provides a map of average thermal conductivity down to 60 metres depth, expressed in W/mK. It is based on all boreholes recorded in the Geological State Office reaching at least 40 metres depth (as of January 2019), evaluated using thermal conductivity values measured in Hamburg. Point-based borehole data are interpolated to derive area-wide conductivity estimates. The dataset supports geothermal potential assessment and planning of shallow geothermal installations across Hamburg, offering a spatial basis for site-specific evaluation of subsurface heat conduction properties.Karte zur mittleren Wärmeleitfähigkeit bis 60 m (in W/mK) Alle im Geologischen Landesamt vorhandenen Bohrungen (Stand: Jan. 2019), die eine Tiefe von mindestens 40 m aufweisen sind mit den in Hamburg gemessenen Werten der spezifischen Wärmeleitfähigkeit (W/mK) ausgewertet worden.
