Building a European geothermal information network using a distributed e-Infrastructure

Abstract

International audienceGeothermal data are published using different IT services, formats and content representations, and can refer to both regional and global scale information. Geothermal stakeholders search for information with different aims. E-Infrastructures are collaborative platforms that address this diversity of aims and data representations. In this paper, we present a prototype for a European Geothermal Information Platform that uses INSPIRE recommendations and an e-Infrastructure (D4Science) to collect, aggregate and share data sets from different European data contributors, thus enabling stakeholders to retrieve and process a large amount of data. Our system merges segmented and national realities into one common framework. We demonstrate our approach by describing a platform that collects data from Italian, French, Hungarian, Swiss and Icelandic geothermal data providers

Reconstructing 3D virtual environments within a collaborative e‐infrastructure

“…D4Science has low cost of maintenance and operation and hosts a rich array of services supporting several application domains . Examples of applications based on D4Science include (i) analyses in fisheries science and marine biodiversity for stock assessment and species distribution estimates, (ii) producing datasets and time series forecasts for climate change and environmental science studies, (iii) processing big data for social mining, and (iv) building semantic networks for cultural heritage . Furthermore, D4Science supports the creation of Virtual Research Environments (VREs), ie, Web‐based domain‐oriented environments that support collaboration between groups of users focussing on the same domain of interest.…”

Cloud computing in a distributed e‐infrastructure using the web processing service standard

“…Services to manage environmental data are today integral parts of many e‐Is . Environmental data are generally offered by several providers under different formats.…”

“…These services can possibly harvest information from other OGC‐compliant services and can publish data under OGC formats to visualise (eg, using the Web Map Service) and to extract information. The D4Science geospatial metadata are stored, indexed, and published on a GeoNetwork instance in ISO‐19139 compliant format according to the INSPIRE directives, in order to maximise the re‐usability of the information by other e‐Is . These metadata can be also discovered and retrieved using the CSW and OAI‐PMH standards.…”

“…Services to manage environmental data are today integral parts of many e-Is. 58,74,75 Environmental data are generally offered by several providers under different formats. Usually, the formats promoted by the open geospatial consortium (OGC) are used, but these allow different representations of the same data content (eg, web coverage service 76 and OPeNDAP 77 for raster data) and thus require services to manage several representations, in order to retrieve and publish information.…”

“…The D4Science geospatial metadata are stored, indexed, and published on a GeoNetwork instance in ISO-19139 compliant format according to the INSPIRE directives, 81 in order to maximise the re-usability of the information by other e-Is. 75 These metadata can be also discovered and retrieved using the CSW and OAI-PMH standards. A Web application allows the D4science users to search for data and visualise/overlay maps 18 .…”
