BRO: the Dutch Key Register of the Subsurface: standardizing public information on the subsurface and making it available to both government and public.

Goal of the BRO

The use of soil and subsurface data by government and private organisations has increased strongly in recent decades, both qualitatively and quantitatively. The data are crucial at operations levels, but also for solving societal problems. Such problems include mitigation of and adaptation to the effects of climate change, like rising sea levels and soil subsidence. Other examples are the use of subsurface information in spatial planning, subsurface constructions, geo-thermal energy and CO2 storage. With the BRO the government aims to strongly improve the accessibility of subsurface information. This is achieved by standardizing public information on the subsurface and making it available to both governmental and other parties. The BRO is part of the national key register system. This system enables the government to improve its services by sharing key data and people, companies, buildings and abo the subsurface within the government. Once the BRO is implemented, all data on the subsurface will be managed in one location and made available for subsequent multiple use.

The BRO is the continuation of the existing registers "Data and Information of the Dutch Subsurface (DINO, including NLOG)" of TNO and the "Soil Information System (BIS)" of Alterra Wageningen University & Research Centre. The archaeological drilling samples will be added. Later on, data on the environmental quality of the subsurface may also be added to the BRO.

A lot of information about the Dutch surface and subsurface comes together in the Key Register of the Subsurface (BRO). As Geological Survey of the Netherlands (GDN), part of TNO, we realize the BRO. The... Read more
