“…[2] discusses interesting ideas regarding query processing in Parliament but does not give implementation details or a performance evaluation. A more detailed discussion of current proposals for adding geospatial features to RDF stores is given in our recent survey [8]. None of these proposals goes beyond the expressive power of stSPARQL or GeoSPARQL discussed in detail above.…”

Abstract. We present Strabon, a new RDF store that supports the state of the art semantic geospatial query languages stSPARQL and GeoSPARQL. To illustrate the expressive power offered by these query languages and their implementation in Strabon, we concentrate on the new version of the data model stRDF and the query language stSPARQL that we have developed ourselves. Like GeoSPARQL, these new versions use OGC standards to represent geometries where the original versions used linear constraints. We study the performance of Strabon experimentally and show that it scales to very large data volumes and performs, most of the times, better than all other geospatial RDF stores it has been compared with.

“…The representation and management of foundational data in Linked SDI is based on the Linked Data principles. For instance, places or locations described in the foundational datasets are expected to have URI with links pointing to other related places based on one or more geospatial relations [29]. In addition, Linked SDIs are also expected to manage thematic Geospatial data (or Framework datasets), such as Earth Observation [18], Land Cover [7], Topography [19] and Administrative Hierarchy [30] datasets as Linked Data.…”

“…Not surprisingly, the concept of Linked Geospatial (or Geospatial Linked) Data, i.e. geospatial data stored in RDF, created, managed and accessible based on the Linked Data principles and standards has appeared in the last few years [11] [12]. Most of Linked geospatial studies have so far aimed at providing an alternative representation format and access method to geospatial data maintained within SDIs.…”

“…The work capitalises on specification of standards, defined by the Open Geospatial Consortium (OGC)(opengeospatial.org), for modeling core concepts related to geospatial data. Prominent examples are GeoSPARQL, an OGC standard [13] and stRDF/stSPARQL [14]. Both proposals provide vocabulary (classes, properties, and functions) that can be used in RDF graphs and SPARQL queries to represent and query geospatial data, for example geo:SpatialObject, which has as instances everything that can have a spatial representation and geo:Geometry as the superclass of all geometry classes.…”

“…RCC8, a QSRR model, has been recently adopted by GeoSPARQL [13], and there is an ever increasing interest in coupling QSR techniques with Linked Geospatial Data that are constantly being made available [14]. On the other hand, Semantic Web reasoning engines have been extended to support qualitative spatial relations, e.g., Racerpro [16] and PelletSpatial [17].…”

Abstract-The Linked Data Web (LDW) is an evolution of the traditional Web from a global information space of linked documents to one where both documents and data are linked. A significant amount of geographic information about places are currently being published on this LDW. These are used to qualify the location of other types of datasets. This paper examines the limitations in the nature of location representation in some typical examples of these Resource Description Framework (RDF) resources, primarily resulting from the simplified geometric representation of location and the incomplete and random use of spatial relationships to link place information. The paper proposes a qualitative model of place location that enforces an ordered representation of relative spatial relationships between places. The model facilitates the application of qualitative spatial reasoning on places to extract a potentially large percentage of implicit links between place resources, thus allowing place information to be linked and to be explored more fully and more consistently than what is currently possible. The paper describes the model and presents experimental results demonstrating the effectiveness of the model on realistic examples of geospatial RDF resources.
