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 …

Abstract The Geosciences and Geography are not just yet another application area for
semantic technologies. The vast heterogeneity of the involved disciplines ranging from the …

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 …

Geospatial semantics as a research field studies how to publish, retrieve, reuse, and
integrate geo-data, how to describe geo-data by conceptual models, and how to develop …

Most of the existing work in the field of Qualitative Spatial Temporal Reasoning (QSTR) has
focussed on comparatively small constraint networks that consist of hundreds or at most …

Geospatial data provenance records sources and processing steps that are used in deriving
geospatial data products. In the Web of Data environment enabled by Linked Data …

We consider chordal RCC-8 networks and show that we can check their consistency by
enforcing partial path consistency with weak composition. We prove this by using the fact …

The pressure of opening access to public sector geospatial information traditionally
managed within disparate spatial data infrastructures (SDI) is driven by a combination of …

We improve the state-of-the-art method for checking the consistency of large qualitative
spatial networks that appear in the Web of Data by exploiting the scale-free-like structure …

We improve the state-of-the-art in checking the satisfiability of large real world qualitative
constraint networks (QCNs), by exploiting the loosely connected structure of their underlying …
