  • This dataset contains the International Bathymetric Chart of the Central Eastern Atlantic (IBCEA), sheets 1.01 ad 1.03, published by the Hydrographic Institute (IH) under the authority of the Intergovernmental Oceanographic Commission (IOC) and the International Hydrographic Organization (IHO).

  • Undersea feature names - Portugal mainland and Azores archipelago.

  • The geological map of Spain and Portugal at 1:1 000 000 scale is a renewed version of the geological map of the Iberian Peninsula and the territories of Ceuta, Melilla and the Balearic, Canaries, Azores and Madeira islands. This small-scale map is edited jointly periodically by the Geological surveys of Spain (IGME) and Portugal (LNEG). This new version includes for the first time the geological information of the Spanish and Portuguese continental shelves and also the geology of the Atlantic Portuguese islands. This map records all the new geological knowledge provided by the complete survey at 1:50 000 scale in Spain (IGME’s MAGNA Plan) and the systematic geological mapping series developed in Portugal by the LNEG. The continental portion of the map was compiled starting from original drafts at 1:400 000 scale made for every main geological unit: Iberian Variscan Massif, Pyrenees, Betics, Cantabrian and Iberian cordilleras and the Duero, Ebro and Tajo Cenozoic basins for the territory of Spain and the geological maps at 1:200 000 scale in Portugal.

  • Geological Map of Portugal, scale 1:1 000 000, LNEG, 2010 modified to be INSPIRE compliant. Layers depicting Geological Units and Faults are available. This dataset was formerly prepared in the framework of the OneGeology-Europe project and harmonised according to INSPIRE vocabularies.

  • The Geological Map of Portugal, scale 1:1 000 000, represents the geology of Portugal onshore and - first time at this scale - offshore. This map is made up of the Geological Map of Mainland Portugal at 1:1 000 000 scale, Geological Map of the Azores Archipelago at 1:1 000 000 scale, Geological Map of the Madeira Archipelago at 1:1 000 000 scale, Geological Map of Portugal Offshore Region at 1:1 000 000 scale, Neotectonic Schema of Mainland Portugal at 1:4 000 000, Tectono-Stratigraphic Schema of Mainland Portugal at 1:5 000 000 scale and Inset Map at 1:20 000 000 scale.

  • This dataset contains the Traffic Separation Schemes (TSS) for navigation safety that have been defined along the Portuguese coast, respectively Cabo da Roca TSS and Cabo de São Vicente TSS. It also includes the Area To Be Avoided (ATBA) of Berlengas.

  • Representa um índice que faz a avaliação da extensão e da intensidade da perda de funções ecológicas e da degradação das terras, incluindo o solo.

  • Assim, a carta do Índice de Aridez, dita pelo método de Penman como à frente se explicita, foi desenvolvida em trabalho conjunto do Instituto de Meteorologia e do Instituto Nacional da Água, tendo como base o cruzamento dos valores das períodos 2000-2010.

  • Representa um índice que apresenta estimativas absolutas da variação do coberto vegetal para cada sítio e durante o decénio em extensão e da intensidade da perda de funções ecológicas e da degradação das terras, incluindo o solo.

  • Avalia a relação dos valores da precipitação (P) com os da evapotranspiração potencial (ETP) para cada local entre os anos 1981 e 2010. A classe das “Áreas Secas” definida por este índice inclui as subunidades: Sub-húmido Seco (P/ETP entre 50% e 65%), Semi-árido (20 -50%) e Árido (5 -20%), sendo que apenas as duas primeiras ocorrem regularmente em Portugal.
