The recent availability of geospatial information as linked open data has generated new interest in geospatial query processing and reasoning, a topic with a long tradition of research in the areas of databases and artificial intelligence. In this paper we survey recent advances in this important research topic, concentrating on issues of data modeling and querying. 
Querying Linked Geospatial Data with Incomplete Information
TLDR
This work discusses the recent work on the model RDF, an extension of RDF with the ability to represent property values that exist, but are unknown or partially known, using constraints, and a extension of the query language SPARQL with qualitative and quantitative geospatial querying capabilities.

Representation and Querying of Valid Time of Triples in Linked Geospatial Data
We introduce the temporal component of the stRDF data model and the stSPARQL query language, which have been recently proposed for the representation and querying of linked geospatial data thatExpand
A Geospatial Semantic Web Visual Query Tool
As geospatial data are becoming more widely used through mobile devices and location sensitive applications, the potential value of linked open geospatial data in particular has grown, and aExpand
Geographica: A Benchmark for Geospatial RDF Stores
TLDR
A benchmark, called Geographica, is developed, which uses both real-world and synthetic data to test the offered functionality and the performance of some prominent geospatial RDF stores. Expand
Ontop-spatial : Geospatial Data Integration using GeoSPARQL-to-SQL Translation
We present Ontop-spatial, a geospatial extension of the wellknown OBDA system Ontop, that leverages the technologies of geospatial databases and enables GeoSPARQL-to-SQL translation. We showcase theExpand
GeoSemOLAP: Geospatial OLAP on the Semantic Web Made Easy
TLDR
GeoSemOLAP is developed to enable users without detailed knowledge of RDF and SPARQL to query the SW with SOLAP and allows the user to interactively formulate queries using a graphical interface with interactive maps. Expand
Geographica: A Benchmark for Geospatial RDF Stores (Long Version)
TLDR
A benchmark, called Geographica, is developed, which uses both real-world and synthetic data to test the offered functionality and the performance of some prominent geospatial RDF stores. Expand
GeoSPARQL Query Tool - A Geospatial Semantic Web Visual Query Tool
TLDR
GeoQuery is presented, a graphical geospatial query tool that is based on Semantic Web technologies that enables queries against any GeoSPARQL endpoint by translating queries expressed via its graphical user interface into GeoSpARQL queries, allowing geographic information scientists and other Web users to query linked data without knowing GeoSParQL syntax. Expand
A foundation for spatial data warehouses on the Semantic Web
TLDR
The QB4SOLAP vocabulary is presented, which supports spatially enhanced MD data cubes over RDF data and defines a number of Spatial OLAP (SolAP) operators over QB4 SOLAP cubes and provides algorithms for generating spatially extended SPARQL queries from the SOLAP operators. Expand

TLDR
The results of the experiment show that by using the intrinsic potential of Linked Data, the application has tackled the challenges of using heterogeneous data sources and have provided desirable information that could be used for discovering new patterns. Expand

Challenges for Qualitative Spatial Reasoning in Linked Geospatial Data
TLDR
Some core research problems that arise when querying linked geospatial data are discussed, and why these are relevant for the qualitative spatial reasoning community are explained. Expand
Enabling the geospatial Semantic Web with Parliament and GeoSPARQL
TLDR
The motivation for GeoSPARQL is described, the current state of the art in industry and research is explained, followed by an example use case, and finally the implementation of GeoSParQL in the Parliament triple store is described. Expand
An introduction to spatial database systems
We propose a definition of a spatial database system as a database system that offers spatial data types in its data model and query language, and supports spatial data types in its implementation,Expand
Geographical Linked Data: The Administrative Geography of Great Britain on the Semantic Web
Ordnance Survey, the national mapping agency of Great Britain, is investigating how semantic web technologies assist its role as a geographical information provider. A major part of this workExpand
Spatially-Augmented Knowledgebase
TLDR
A prototype system for storing spatial data and Semantic Web data together in a SPatially-AUgmented Knowledgebase (SPAUK) without sacrificing query efficiency is described. Expand
Geospatial semantic Web: architecture of ontologies
TLDR
This paper outlines five interrelated ontologies that support a complete semantic geospatial system and encourages the development of these ontologies into useful standards for further exploitingGeospatial data and services. Expand
Toward the semantic geospatial web
TLDR
By explicitly representing the role of semantics in different components of the information retrieval process (people, interfaces, search systems, and information resources), the Semantic Geospatial Web will enable users to retrieve more precisely the data they need, based on the semantics associated with these data. Expand
Supporting Complex Thematic, Spatial and Temporal Queries over Semantic Web Data
TLDR
This paper describes a framework built around the RDF metadata model for analysis of thematic, spatial and temporal relationships between named entities and describes an efficient implementation in Oracle DBMS and demonstrates the scalability of the approach. Expand
Modeling and Querying Metadata in the Semantic Sensor Web: The Model stRDF and the Query Language stSPARQL
TLDR
The data model stRDF and the query language stSPARQL are developed, a constraint data model that extends RDF with the ability to represent spatial and temporal data and follows the main ideas of constraint databases. Expand
Supporting Spatial Semantics with SPARQL
TLDR
A set of desiderata for a query language capable of dealing with spatial Semantic Web-based data is established, the challenges facing such a querylanguage are discussed, and these challenges are addressed with straightforward solutions that are broadly applicable. Expand
