Geospatial data is vital for many application scenarios, such as navigation, logistics, and tourism. At the same time, a large number of currently available datasets (both RDF and conventional) contain geospatial information. Examples include DBpedia, Wikidata, Geonames, OpenStreetMap and its RDF counterpart, LinkedGeoData. RDF stores have become robust and scalable enough to support volumes of billions of records (RDF triples). Despite improving implementations and standards such as GeoSPARQL, traditional geospatial data management systems still outperform them in functionality, efficiency and scalability regarding geospatial content. On the other hand, geospatial information systems (GIS) can benefit from Linked Data principles (e.g., schema agility and interoperability).

The goal of the GeoLD workshop is to provide an opportunity for the Linked Data community to focus on the emerging need for effective and efficient production, management and utilization of Geospatial information within Linked Data. Emphasis will be given to works describing novel methodologies, algorithms and tools that advance the current state of the art with respect to efficiency or effectiveness. We welcome both mature solutions, as well as ongoing works that present promising results.

Topics include, but are not limited, to the following:

*Interoperability and Integration*
Geospatial Linked Data vocabularies and standards (GeoSPARQL, INSPIRE, W3C, OGC)
Extraction/transformation of Geospatial Linked Data from native geospatial data sources
Integration (schema mapping, interlinking, fusion) techniques for Geospatial RDF Data
Enrichment, quality and evolution of Linked Data with Geospatial information
Machine Learning improving Geospatial Linked Data processing

*Big Geospatial Data Management*
Distributed solutions for Geospatial Linked Data management (storing, querying, mapping)
Algorithms and tools for large scale, scalable Geospatial Linked Data management
Efficient Indexing and Querying of Geospatial Linked Data
Geospatial-specific Reasoning on RDF Data
Ranking techniques on querying Geospatial RDF Data
Advanced querying capabilities on Geospatial RDF Data

*Utilization of Geospatial Linked Data*
Benchmarking of Geospatial Linked Data applications
Geospatial Linked Data in social web platforms and applications
Visualization models/interfaces for browsing/authoring/querying Geospatial Linked Data
Real world applications/use cases/paradigms using Geospatial Linked Data
Evaluation/comparison of tools/libraries/frameworks for Geospatial Linked Data


Submission instructions
=======================
All papers must be original and not simultaneously submitted to another journal or conference. The following paper categories are welcome:​​​​​​​

- Long papers (up to 12 pages): Presenting novel scientific research pertaining to querying the Web of Data.
- 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 of the Springer Publications format for Lecture Notes in Computer Science (LNCS). For details on the LNCS style, see Springer’s Author Instructions. We accept PDF submissions as well as HTML submissions in RASH or dokieli.

Papers must be submitted through the EasyChair system at https://easychair.org/conferences/?conf=geold2018 no later than midnight Friday March 2, 2018, Hawaii Time. 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.
