3D Geological modelling is a technique for creating 3D representations of the underground based on geological and geophysical observations and concepts. It is used for managing and quantifying natural resources, with applications such as groundwater, geothermal and coal exploration.


The Flemish Knowledge Center of the Subsoil (VLAKO) is a Task Force within VITO that conducts policy-supporting research for the Flemish Government.

VLAKO carries out various research tasks:

  • 3D (hydro)geological mapping (geological and hydrogeological layers and faults) of Flanders and beyond
  • Resource (raw materials) mapping
  • Geological data collection and management in the context of the Geosciences Database of Flanders (DOV)

  • Policy support
  • Subsurface applications (geothermal, groundwater, mining, …)
  • Reserve estimations of subsurface resources
