  • Geological Map of Portugal, at scale 1:200 000, composed of the sheets published at this scale (Sheets: 1, 2, 4, 6, 7 and 8).

  • The Biomethane Atlas serves to support the identification of the most favorable locations for the implementation of biomethane production units, considering proximity to biogas sources (potential producers), potential consumers, and/or the gas network. It is developed using GIS software for mainland Portugal. The analysis is performed to identify clusters of producers/consumers in proximity, considering the division of the country into a 20km² grid (278 grid squares in mainland Portugal). For each of these, the current potential quantity of biomethane production in m³/year was estimated for the following types of potential producers: (1) Waste and Wastewater: municipal waste landfills, industrial waste landfills, and wastewater treatment plants; (2) Agro-industry: Other food products; Milk; Breweries; Slaughterhouses; Tomatoes; Juices/Salads; Rice husks and Dried fruits; (3) Olive mills and wineries: Olive pomace; Olive mills; Wineries and distilleries; (4) Intensive Livestock Farming: Poultry; Ruminants and Pigs; (5) Agricultural Byproducts: Tomatoes; Corn; Rice paddies; Olive grove pruning; Orchard pruning and Vine pruning. The following potential consumers were considered: (1) Refineries and CCGT Combustion Plants; (2) Industry: Glass; Chemical; Cement; Ceramics; Paper/Cardboard; Agri-food and Textile; (3) Vehicle gas refuelling stations; (4) Autonomous Gas Units; and (5) Injection points in the natural gas grid. A dimensionless index was developed that characterizes each grid square according to its suitability and ranges from 0 to 100 (100 is higher/better). The index can be viewed only for producers, for consumers, and for the combination of producers and consumers. A cell with many potential producers of high volumes of biomethane and potential consumers will have a higher value in the index. The location of production projects and areas with limitations for the application of digestates in soils are also shown. The Atlas does not replace case-by-case analysis of project location or licensing. It should be used for informational purposes only. The scale of analysis used is limited by the resolution and accuracy of the underlying information.

  • Geological Map of Portugal at scale 1:50 000, consisting of sheets published at this scale in paper and/or digital format. Includes geological maps of the Madeira and Azores Archipelagos.

  • QAFI is a database of faults with geological evidence of proven activity during the Quaternary period (the last 2.6 million years according to the limit officially established by the SQS in 2009) of the Iberian Peninsula.

  • 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.

  • The marine energy potential maps for mainland Portugal consists of the mapping the main wind and wave parameters for the offshore environment at the height of 100m (offshore wind resource) and at surface (wave energy resource). The offshore wind resource is performed with a sophisticated mesoscale atmospheric model, capable of describing the main wind phenomenology near the Portuguese coast, and contains the mapping of the average wind speed [m/s], Wind Power Flux [W/m2] and the map of the annual number of hours at full capacity NEPS of a standard reference turbine as well as the NEPS maps [h/year] for specific type of bottom-fixed wind turbine systems - "Jacket" and "Monopile" or Floating – WindFloat. The offshore wind resource maps represent the climatology of the wind resource as well as characteristics of the wind phenomenology associated to the land-sea interaction along the Portuguese coast. Regarding the wave energy maps, the estimation of the wave energy resource is based in estimating the main sea-wave characteristics and the wave energy production for standard different wave system types – oscillation water column converter; floating two-body heaving converter bottom-fixed oscillating flap converter. The maps of the wave energy resource are a merging of observational data (boys) and information from the ONDATLAS database as well as data from numerical modeling with the MAR3G model all with 10 years of data . This way the wave energy resource maps describe the main characteristics of the average wave resource for a period of 10 years, which is representative of the sea state climatology of Portugal. All wave energy maps are expressed in [kW/m]. Also, all wind and wave energy resource maps are processed with a high spatial resolution of 1km x 1km from the coast up to the bathymetric of 300m. Some wind and wave energy maps are freely available to download in a course but larger grid area (5Km x 5Km). In time, the offshore wind maps will include higher heights.

  • The Critical Raw Materials Deposits Map in Mainland Portugal is a compilation of the known mineral occurrences and deposits of the most critical raw materials according to the latest list published by the European Commission in 2023.
