Apologies for cross-posting! ------------------------------------------------- Dear all, We are happy to announce that the 5th International Workshop on Geospatial Linked Data will be co-located with the European Semantic Web Conference (ESWC) in May 2022. Details are published on the website: https://i3mainz.github.io/GeoLD2022/ Abstract: ------------- Geospatial data are essential not only for many traditional GIS tasks such as navigation, logistics, and tourism, but even more for emerging technologies like autonomous vehicle navigation, smart city technologies, and further location-based services. For all these technologies, geospatial linked data (GLD) is a crucially important source of machine-readable pre-interpreted information. Recently, we can observe a transformation process of spatial data infrastructures from previously merely acting as data providers to becoming brokers of geospatial information of different kinds, origins, quality, and a need to interconnect and incorporate information of different data repositories, often even in real-time. This need for GLD integration leads to efforts to create next-generation knowledge graphs which integrate multiple spatial datasets with large numbers of general datasets containing some geospatial references (e.g., \emph{DBpedia, Wikidata}) and even volunteered geographic information (e.g., \emph{LinkedGeoData}) and sensor data. This integration, either on the public Web or within organizations has immense socio-economic and academic benefits. The upsurge in linked data-related presentations in the Eurogeographics data quality workshop series, in relevant journal publications, in activities of standardization bodies (OGC GeoSPARQL), and in Spatial Data Applications shows a deep interest in GLD in national mapping agencies and beyond. GLD enables web-based, interoperable geospatial data infrastructures that may enhance and support existing standardization efforts like Europe's INSPIRE directive. Moreover, geospatial information systems benefit from Linked Data principles in building the next generation of spatial data applications, e.g., federated smart buildings, self-piloted vehicles, delivery drones, or automated local authority services, which is of increasing interest to various stakeholders. This workshop invites papers covering the challenges and solutions for handling GLD, especially for building high-quality, adaptable, geospatial data infrastructures and next-generation spatial applications. We aim to demonstrate the latest approaches and implementations and to discuss the solutions to challenges and issues arising from research and industrial organizations.
