Due to the Dutch Key registry of the Subsurface Act (BRO), a wealth of information regarding the Dutch subsurface is available through the BROloket portal. Whether you seek insights into soil types or groundwater levels, all pertinent data is consolidated in one convenient location, accessible to all. 


Key registry of the Subsurface Act

Since January 1, 2018, the Key registry of the Subsurface Act has been instrumental in systematically collecting extensive data on the subsurface. The Key registry of the Subsurface serves as a centralized repository of reliable data and information on the Dutch subsurface. Public authorities record standardized data for easy access and reference. From this central digital hub, users can seamlessly retrieve information on soil and subsoil, enhancing decision-making processes.

As urban sprawl expands upon our soil and subsoil, effective policy and management are important. The Netherlands leads as the first country to regulate subsurface mapping by law, mandating administrative bodies to both provide and utilize subsurface data. One of the key benefits is that this enebles us to utilize this data for a Digital Twin of the underground.


Accessible subsurface data

The BRO aims to significantly enhance the provision of subsurface information by consolidating data generated by public institutions. It is obligatory for anyone undertaking governmental assignments to utilize the BRO, ensuring comprehensive and standardized data usage. Moreover, the BRO continues to expand as more measurement data is incorporated, enriching its utility over time.

As the digital landscape evolves, so too does our understanding of the subsurface. With the BROloket portal, exploring Dutch subsurface data has never been more accessible or enlightening. From geological models to real-time dynamic data.

Next tot that, we are facing significant societal challenges, in which the subsurface plays a important role. Over the past years, Sogelink has actively contributed to the Basic Registration of Subsurface (BRO), for example with providing a Digital Twin of the Lekdijk, collaborating with other stakeholders to solve complex issues using subsurface data.
