GeoLinked Data (.es) is an open initiative whose aim is to enrich the Web of Data with Spanish geospatial data. This initiative started off by publishing diverse information sources belonging to the Spanish National Geographic Institute. Such sources are made available as RDF (Resource Description Framework) knowledge bases according to the Linked Data principles. With this work, Spain has joined the Linked Data initiative, in which the United Kingdom and Germany are already participating. In this presentation, we provide an overview of the process that has been followed for the development of this initiative.
