About us

ThermoGIS is developed by TNO Geological Survey of the Netherlands (TNO-GDN). The ThermoGIS team, comprising staff from across the different departments of TNO-GDN, brings together knowledge and expertise on the Dutch subsurface.

Within ThermoGIS, TNO-GDN’s information and research activities come together. Research carried out by the research departments is translated into models, calculation tools and accessible maps that serve as information products. In this way, specialist knowledge of the subsurface is made accessible and useful to public authorities, consultants, companies and other professionals working on geothermal energy and heat storage.

ThermoGIS is continuously evolving. New data, models and research results can be incorporated, ensuring that the available information reflects the latest knowledge and remains relevant to current challenges in the heat transition. This continuous development also reflects ThermoGIS’ role as an information product that integrates new data, knowledge and models

About Geological Survey of the Netherlands

TNO Geological Survey of the Netherlands (TNO-GDN) is the foremost independent knowledge centre for the subsurface of the Netherlands. Every day, it puts fundamental and applied knowledge and research about the subsurface and its use to work for society. TNO-GDN informs and advises public authorities, the business community, and society - both domestically and abroad. In addition, it conducts research focusing on current or potential future needs and requirements.

Portals: Take a dive into the subsurface

TNO-GDN has been collecting subsurface data for more than a century. In this way, a wealth of information has been generated through drillings, probings, seismic surveying, field recordings, groundwater measurements, and laboratory analyses. The portals of TNO-GDN, listed below, allow you to view and use a large amount of data and information about the subsurface. One of the portals is ThermoGIS. See the other portals below:

BROloket

You can use BROloket (only in Dutch) to access and download online subsurface data and models falling under the Dutch Key Registry of the Subsurface Act.

DINOloket

DINOloket allows users to view, request and download data and data models relating to the subsurface. The map application offers many possibilities to filter data to obtain the desired information.

NLOG

NLOG provides information on energy and mineral resources in the deep subsurface. It contains public data on the exploration and production of natural gas, crude oil, geothermal energy and rock salt, as well as on the storage of substances such as natural gas and CO₂.

Delfstoffenonline

Delfstoffenonline (only in Dutch) provides information about the surface minerals of the Netherlands, such as gravel, sand and clay.

Grondwatertools

Through the interactive grondwatertools (only in Dutch) website, you can found out more about the hydrogeological structure of the subsurface, groundwater levels and head levels, and the composition of groundwater.

Geodeatlas

GEODE is a joint project of EBN and TNO and aims to create an atlas to unlock opportunities for exploration in the Dutch offshore, including oil and gas exploration and CO₂ storage.
