“When we see the power of integrating geospatial data with other data, that’s when we see real potential.”
Nadine Alameh, chief executive officer, Open Geospatial Consortium (The Economist Intelligence Unit)

Call for Papers and topics

Geospatial data is vital for both traditional applications like navigation, logistics, and tourism and emerging areas like autonomous vehicles, smart buildings and GIS on demand. Spatial linked data has recently transitioned from experimental prototypes to national infrastructure. However the next generation of spatial knowledge graphs will integrate multiple spatial datasets with the large number of general datasets that contain some geospatial references (e.g., DBpedia, Wikidata). This integration, either on the public Web or within organizations has immense socio-economic as well as academic benefits. The upsurge in Linked data related presentations in the recent Eurogeographics data quality workshop shows the deep interest in Geospatial Linked Data (GLD) in national mapping agencies. GLD enables a web-based, interoperable geospatial infrastructure. This is especially relevant for delivering the INSPIRE directive in Europe. 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.

This workshop invites papers covering the challenges and solutions for handling with GLD, especially for building high quality, adaptable, geospatial 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.

Short papers (up to 6 pages): Position papers, System, Library, API and Dataset descriptions, relevant to the topics of interest.
Demo/Tutorial papers (up to 4 pages): Describe a demo or hands-on tutorial of a tool on the workshop topics.

Submissions must be in English formatted in the style CEURART of CEUR-WS (single column). For details on the CEUR-WS CEURART style, see CEUR-WS Author Instructions. We accept PDF submissions.

Papers must be submitted through the EasyChair system no later than midnight March 6th, 2022, Anywhere on Earth TimeZone. Submissions will be reviewed by members of the workshop program committee. Papers will be evaluated according to their significance, originality, technical content, style, clarity, and relevance to the workshop.

The complete set of papers will be published with the CEUR Workshop Proceedings (CEUR-WS.org) and listed by the DBLP.

KEYNOTE

We are happy to announce that our keynote speaker will be Erwin Folmer.
Erwin Folmer received the M.Sc. degree in industrial engineering and management in 1999 and the Ph.D. degree on the thesis “Quality of Semantic Standards” in 2012, both from the University of Twente, the Netherlands. He worked for TNO (Netherlands Applied Research Institute) since 2001, and became a Senior Scientist on the topic of interoperability and standards. From 2009, he joined (part-time) the University of Twente to start a Ph.D. research on the standardization topic, while continuing the work for TNO. From 2013 to 2014, he was a Visiting Researcher with the ERCIS/University of Munster, in Germany. From 2015 onwards, he joined the Kadaster, continuing the work on standards and interoperability with special focus on spatial data platforms. Nowadays he is leading the Kadaster Data Science Team. He is also chairing the Platform Linked Data Netherlands; an open community to support the Linked Data adoption.

KeyNote Title: Lessons Learned from Building the Largest Spatial Knowledge Graph in the Netherlands
Abstract: Kadaster, the Dutch National Land Registry and Mapping Agency, has been actively publishing their base registries as linked (open) spatial data for several years. To date, a number of these base registers as well as a number of external datasets have been successfully published as linked data and are publicly available. Increasing demand for linked data products and the availability of new linked data technologies have highlighted the need for a new, innovative approach to linked data publication within the organisation in the interest of reducing the time and costs associated with said publication. Both the modelling and publication architecture form part of Kadaster’s larger vision for the development of the Kadaster Knowledge Graph through the integration of the various linked datasets. In this presentation Erwin will focus on the lessons learned from building (probably) one of the largest spatial knowledge graphs in the world. He might also want to challenge the participants by talking about his greatest frustration: GeoSPARQL.
