GeoSPARQL 1.1: Motivations, Details and Applications of the Decadal Update to the Most Important Geospatial LOD Standard

Abstract: In 2012, the Open Geospatial Consortium published GeoSPARQL defining “an RDF/OWL ontology for [spatial] information”, “SPARQL extension functions” for performing spatial operations on RDF data and “RIF rules” defining entailments to be drawn from graph pattern matching. In the 8+ years since its publication, GeoSPARQL has become the most important spatial Semantic Web standard, as judged by references to it in other Semantic Web standards and its wide use for Semantic Web data. An update to GeoSPARQL was propo… Show more

“…The properties of the spatial ontology mainly define the topological spatial relations between geographic objects, as well as the geometry literal [26], which is the serialization standard used when generating geometry descriptions and the supported geometry types. In addition, the properties of the spatial ontology also include Metric [26], which are scalar spatial properties that describe the geographic object. The main rule of the spatial ontology includes basic ontology constraints for class and property, such as constraints on hierarchical relationships between classes and constraints on property values.…”

“…Linked Data and Semantic Web technologies may assist in aligning and linking EO data with each other, but also other kind types of geo-information, using the Resource Description Framework (RDF) for interconnecting data. W3C has proposed standards for representing and querying geospatial data in RDF allowing for topological querying in RDF with GeoSPARQL 1,2 . Such vocabularies and querying languages have been adopted by OpenStreetMaps, DBpedia, and Ordinance Services across the world.…”

“…In addition, some properties of classes and relationships can be stated as part of the ontology. Geo-ontologies usually base their foundation on the primary schema of GeoSPARQL ontology [7] which contains "spatial object" as the main class with two subclasses namely "feature" and "geometry". A spatial object is defined as anything spatial (being or having a shape, a position, or an extent).…”

“…For example, a river is a feature and hence can be linked to a point object (subclass geometry) which can represent a geocoordinate [7]. An important design feature of the GeoSPARQL and almost all the other related ontologies [7,28,31,42] describing geographical aspects is that they define qualitative spatial relations as object properties e.g. {Entity: Place1, ObjectProperty: west, Entity: Place2}.…”
