Abstract

This work describes the implementation of the INSPIRE Geology data model
(INSPIRE GE) for digital geological map production at the Portuguese Laboratory
of Energy and Geology (LNEG). The process of harmonising geological mapping
data involves the restructuring of the LNEG’s current data model into the
extended INSPIRE GE, which aims a more efficient, interoperable and
harmonized management data structure. The methodology, which is compliant
with the Portuguese geology requirements, was applied to the Rosário antiform,
a geological structure located in the Iberian Pyrite Belt. Three maps were
produced: (i) a geologic map representing the geological units organized
according to their spatial distribution and age; (ii) a lithologic map representing
the most important rock types; and (iii) an age map representing the lower
boundary age of the geological units. This study improves current LNEG's data
structuring and geological map production flow. It also shows that the INSPIRE
GE implementation is feasible and that it constitutes the first step toward data
harmonization and interoperability in LNEG geological mapping activities.
