Data types

Over the period 2018-2022, the first phase of the BRO register will be gradually put in place. Following each phase, the BRO will contain more information about both the deep and shallow subsurface environment. This information will be classified on the basis of data types, referred to as registration objects or RO’s. In total there will be around 24 registration objects.

Five domains

The registration objects are shared across five domains:

  1. Soil and subsurface investigation
  2. Groundwater monitoring
  3. Groundwater use
  4. Mining Act
  5. Models and maps

1. Subsurface research

Registration objects:

  • Cone penetration test (CPT)
  • Borehole research (BHR)
  • Borehole research-Pedology (BHR-P)
  • Borehole research-Geotechnics (BHR-GT)
  • Borehole research-Geology (BHR-G)
  • Borehole research-Applied Geology (BHR-AG)
  • Soil face research (SFR)

2. Groundwater monitoring

Registration objects:

  • Groundwater monitoring well (GMW)
  • Groundwater level dossier (GLD)
  • Groundwater analysis report (GAR)
  • Groundwater monitoring network (GMN)
  • Formation resistance dossier (FRD)

3. Groundwater use

Registration objects:

  • Groundwater utilisation facility (GUF)
  • Groundwater production dossier (GPD)

4. Mining Act

  • Exploration production (and storage) licence (EPL)
  • Exploration production construction (EPC)

5. Models and maps

  • Soil and groundwater  map (SGM)
  • Geomorphological map (GMM)
  • Hydrogeological model (HGM)
  • Digital Geological Model (DGM)
  • GeoTOP model (GTM) [more information in the storymap]
  • Water Table Depth Model (WDM)

Standardisation process

For each RO a data model is constructed. This is done in close cooperation with stakeholders and experts from the domain who understand the data itself as well as the business processes being used during the acquisition and processing of the data. During this standardisation process the data model is published on internet periodically for public review, making it fully  transparent and giving every stakeholder the opportunity to provide feedback. In the end a formal document (catalogue) is produced describing the context of the RO and the semantic data model (entities, attributes, business rules) in detail.
