Descrição

Article under Review - Submitted 2013-06-14 This work deals with the implementation of the INSPIRE Geology data model (INSPIRE GE) in digital geological map production in the Portuguese Laboratory of Energy and Geology (LNEG), and its extension to comply with the Portuguese geology requirements. The process of harmonising geological mapping data involves the restructuring of the LNEG’s data model to the extended INSPIRE GE which aim at building a more efficient, inter-operable and harmonised management data structure for geological mapping, across the European Community. The methodology was applied to the Rosario Antiform, a geological structure that belongs to the Portuguese part of the Iberian Pyrite Belt. Three maps concerning the Antiform were produced, namely: (i) The lithostratigraphic map representing the geological units organized according to their spatial distribution and age; (ii) The age map which represents the lower age of the geological units; and (iii) The lithological map where the most important rock types are represented. This study shows that the INSPIRE GE implementation is feasible in the geological mapping production at LNEG and it constitutes a first step towards data harmonisation and inter-operability. The structuring of geological data allows the implementation of geoprocessing operations in the production of geological and other thematic maps (e.g. lithologic map, age map).
