Examples

All data for a particular object (a hotel in Berlin)

The GeoSPARQL.org website was developed and is maintained by Marco Neumann.
It may deviates from the Apache Jena project implementation but where possiblei
extends the Apache Jena project.

SPARQL | JenaSpatial (replaced geospatial index for jena)

GeoSPARQL.org is based on work by Marco Neumann first published in
"Spatially Navigating the Semantic Web" at the First International Workshop on Semantic Web
and Databases. VLDB 2003

The first public online demostrator for GeoSPARQL was released in January 2008
as part of the geospatialweb project.
