In this blog post, the author discusses the relative lack of spatial indexes for data in RDF triple stores, compared to data stored in GIS systems and a number of spatially enabled relational databases. He shares an example using the Ordnance Survey Data's API to obtain a location's URI, which is then used to construct a series of SPARQL queries based on several spatial relationships related to that location.
