Hydrogeological Map of Portugal, scale 1:200,000, composed of published sheets in analogical and/or digital format (Sheets 1, 6, 7 and 8). More detailed information on each of the sheets is available at the following addresses: Sheet 1 - https://sig.lneg.pt/metadados/catalog/search/resource/details.page?uuid=e58236aa-fa9b-4f7a-9f23-2d7a7e2ad41c; Sheet 6 - https://sig.lneg.pt/metadados/catalog/search/resource/details.page?uuid=32b26db5-14b9-4fd5-a240-8a016bb4e8bd; Sheet 7 - https://sig.lneg.pt/metadados/catalog/search/resource/details.page?uuid=8e8b5faf-bb9b-4c36-b59c-f3dadcbda478; Sheet 8 - https://sig.lneg.pt/metadados/catalog/search/resource/details.page?uuid=fef640c6-d353-4ba0-adb8-65b7c5afccc9.

The onshore wind potential map of mainland Portugal contains the mapping of the main wind parameters at two reference heights, 20m and 80m such as the average wind speed (m/s), Incident Wind Power Flow (W/m2), Weibull parameters: Scale factor A (m/s) and Weibull Form factor k (dimensionless) and the map of the annual number of hours at full capacity (NEPs) of a standard reference turbine. Due to the advancement of wind technology, wind farms are starting to operate with wind turbines with hub heights at least, 100m high. In this sense, the renewable wind mapping (NEPs) at 100m is also available, taking into account the current actual technology.

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 Portuguese HydroGeological Resources Database provides geological and hydrogeological information for drill holes, wells, springs and boreholes.

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.

This map was developed to integrate the 2nd version of the PNS - Portuguese Natural Stones - Portal. It contains points, which correspond to the geographic coordinates (central) of the quarrying site(s) where the natural stones included in PNS Portal are quarried. Selecting each point on the map allows access to a table, which includes: - stone code on the PNS Portal; - main commercial names; - stone type; - petrological family; - geographic coordinates (EPSG 4326); - link to the stone’s Technical Sheet, on the PNS Portal.

The “National Atlas of Sustainable Green H2” is a tool based on georeferenced information that follows defined criteria in the development of scenarios to assess the suitability of the location of green hydrogen production projects with regard to: (i) necessary resources to power hydrogen production plants through water electrolysis; (ii) land use conditions for the implementation of green hydrogen production units, and (iii) factors that enhance the commercialization of the produced hydrogen. Based on this “National Atlas of Sustainable Green H2” tool, we present 4 maps referring to 4 scenarios that identify the “best” areas for green hydrogen production according to the basic rationale of each scenario. The 4 maps represent the following scenarios: scenario A “Diversified”, scenario B “Drought, Gas Grid and Transport”; scenario C “Drought and gas consumers”; scenario D “Prospective”. Each scenario was developed based on 3 sub-indices (i) proximity to water sources, (ii) proximity to energy sources and (iii) ease of commercializing green H2 on the market. The water sub-index consists of a maximum of 7 indicators considering the proximity to the following potential water sources: surface water bodies, wastewater treatment plants (WWTPs), public water network, groundwater, seawater, multi-purpose irrigation grid, water scarcity index. The energy sub-index consists of a maximum of 6 indicators, namely: solar resource, onshore wind resource, offshore wind resource, proximity to bioelectricity producers, proximity to hydropower producers, proximity to the power grid. Finally, the market sub-index is made up of a maximum of 5 indicators, including proximity to: potential industry consumers of H2, potential transport consumers of H2, potential consumers of H2 as raw material, large CO2 emitters. Each final map excludes from potential project locations land occupation that proves to be inappropriate. The following are not yet considered: easements and public utility restrictions, RAN and REN areas, Territorial Planning Plans, municipality land planning (PDM), SEVESO Directive hazardous zones, protected areas under the Water Framework Directive , seismicity, flood risk and/or geologically unstable areas (erosion, landslides, etc.). This Atlas requires a detailed analysis of sites considering all applicable legislation. The geographic information used has inherent limitations regarding date, scale, resolution and sources. Furthermore, the viability assessment for a specific project requires detailed information that goes beyond the variables contained in this Atlas and considers other decision-making and legal compliance factors, which cannot be considered at this scale.
