Prevailing solutions are document oriented and fragment the spatial continuum of the geospatial data into independent and disconnected resources described through metadata. Due to this, the complete answer for a query may be scattered across multiple resources, making its discovery and access more difficult. This paper proposes an improved information retrieval process for geospatial data catalogs that aggregates the search results by identifying the implicit spatial/thematic relations between the metadata records of the resources. These aggregations are constructed in such a way that they match better the user query than each resource individually. info:eu-repo/grantAgreement/ES/DGA/C38-2015 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.37 2017 COMPUTER SCIENCE, INFORMATION SYSTEMS 54 / 148 = 0.365 2017 Q2 T2 GEOGRAPHY 23 / 83 = 0.277 2017 Q2 T1 INFORMATION SCIENCE & LIBRARY SCIENCE 23 / 88 = 0.261 2017 Q2 T1 GEOGRAPHY, PHYSICAL 24 / 49 = 0.49 2017 Q2 T2 1.113 2017 Geography, Planning and Development 2017 Q1 Library and Information Sciences 2017 Q1 Information Systems 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-6491-7430 Lopez-Pellicer, F.
