The Geothermal Atlas of Mainland Portugal is a mission-driven project of fundamental importance for the geothermal knowledge of the country, systematically carried out at the National Laboratory of Energy and Geology (LNEG) for over 30 years. It was created following other mapping projects, incorporating diverse information from various data sources obtained for different purposes, from different institutions, and harmonized and processed in a way that allows it to be applied to information, dissemination, training, promotion, and research on geoenergy in mainland Portugal, thus serving as a lever for the sector's development. It constitutes a dynamic and constantly updated research effort, integrating various parameters from diverse origins applicable to geoenergy studies. Its integrated and homogenized processing allows for a visualization of the country's geothermal characteristics on a national scale and can be used to determine geothermal potential at various scales. As sources of information for the production of geothermal mapping of mainland Portugal, processed and directed towards the various types of geothermal energy and geothermal exploitation, the first works began more than 40 years ago, forming the basis of Portuguese contributions to successive European Atlases of Geothermal Resources, the last of which was published in paper in 2002 with updates published in 2025 in the European Geological Data Infrastructure. This information is constantly complemented by additional geothermal information, whose original acquisition was made for geothermal purposes, and also by information acquired for other geoscientific objectives. The incorporation of information is done according to established criteria.

Prototype of a seamless data model of the Digital Geological Map of Portugal, at scale 1:200 000, in which the mapped units of mainland Portugal were inventoried and organized according to a unified legend (LU). Standardization and harmonization work was carried out between contiguous maps, as well as updating the units through extensive bibliographic research and, above all, leveraging on the experience and knowledge existing at LNEG. The following elements are available: LU code, unit code, unit name, and associated lithological description. This work is under development and reflects the situation as of September 2025.

Geological map data of Portugal at scale 1:1 000 000 modified according to INSPIRE data specifications for the Geology theme. Layers depicting Geologic Units are classified according to ages and lithologies from INSPIRE vocabularies, faults and geomorphologic features are also available. This dataset was formerly prepared in the framework of the OneGeology-Europe project. The faults are harmonized based on the work done within the scope of the HIKE project.

The national radiometric map began to be drawn up in the 1950s for uranium prospecting and represents the natural radioactivity measurements based in old and new surveys and calibration and harmonization of these data. The mapping of the country's natural radiation allows supporting exploration for mineral and geothermal resources, geological mapping and hazard studies.
