- Landslide monitoring techniques in the Geological Surveys of EuropePublication . Auflič, Mateja Jemec; Herrera, Gerardo; Mateos, Rosa María; Poyiadji, Eleftheria; Quental, Lídia; Severine, Bernardie; Peternel, Tina; Podolszki, Laszlo; Calcaterra, Stefano; Kociu, Arben; Warmuz, Bartłomiej; Jelének, Jan; Hadjicharalambous, Kleopas; Becher, Gustaf Peterson; Dashwood, Claire; Ondrus, Peter; Minkevičius, Vytautas; Todorović, Saša; Møller, Jens Jørgen; Marturia, JordiABSTRACT: Landslide monitoring is a mandatory step in landslide risk assessment. It requires collecting data on landslide conditions (e.g., areal extent, landslide kinematics, surface topography, hydrogeometeorological parameters, and failure surfaces) from different time periods and at different scales, from site-specific to local, regional, and national, to assess landslide activity. In this analysis, we collected information on landslide monitoring techniques from 17 members of the Earth Observation and Geohazards Expert Group (from EuroGeoSurveys) deployed between 2005 and 2021. We examined the types of the 75 recorded landslides, the landslide techniques, spatial resolution, temporal resolution, status of the technique (operational, non-operational), time of using (before the event, during the event, after the event), and the applicability of the technique in early warning systems. The research does not indicate the accuracy of each technique but, rather, the extent to which Geological Surveys conduct landslide monitoring and the predominant techniques used. Among the types of landslides, earth slides predominate and are mostly monitored by geological and engineering geological mapping. The results showed that Geological Surveys mostly utilized more traditional monitoring techniques since they have a broad mandate to collect geological data. In addition, this paper provides new insights into the role of the Geological Surveys on landslide monitoring in Europe and contributes to landslide risk reduction initiatives and commitments (e.g., the Kyoto Landslide Commitment 2020).
- INSPIRE data harmonisation of mineral resources: contribution of MINERALS4EU projectPublication . Lopes, Catarina; Quental, Lídia; De Oliveira, Daniel Pipa Soares; Filipe, Augusto; Pereira, AureteABSTRACT: Georesources support society at different levels, depending on their technological development, and thus strongly impact on the economic, societal and environmental sustainability pillars. The European project MINERALS4EU [5] created the European Mineral knowledge Data platform (EU-MKDP [6]), to provide harmonised data related to mineral resources, as well as statistical related information, e.g., minerals yearbook. The nuclear pillars of the EU-MKDP architecture were based in the datamodels and harmonised terminology developed by INSPIRE and IUGS-CGI (represented by GeoSciML and EarthResourceML). The Portuguese input to this platform was based on mineral occurrences and resources information system, SIORMINP [15]. SIORMINP contains information of categorization of mineral potential, past concessions, commodities reserves and resources, and exploitation activity. The SIORMINP dataset was harmonised according to the MINERALS4EU project data model and vocabularies, and published using OGC compliant Web services in EU-MKDP. This work shows how the data harmonization was undertaken to integrate national database in the EU-MKDP, and more recently to improve the national geoportal to be INSPIRE compliant.
- INSPIRE Geology data model implementation in digital geological map production in Portugal : a preliminary approachPublication . Pereira, Aurete; Luís, Gabriel; Cabral, Pedro
- Implementation of INSPIRE Directive in Digital Geological Map Production in PortugalPublication . Pereira, Aurete; Luís, Gabriel; Cabral, PedroThis 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).
