Recently we have seen a large increase in the amount of geospacial data that is being published using RDF and [Linked Data principles](http://www.w3.org/DesignIssues/LinkedData.html"). Efforts such as the W3C Geo XG, and most recently the GeoSPARQL initiative are providing the necessary vocabularies to publish this kind of information on the Web of Data. map4rdf is a mapping and faceted browsing tool for exploring and visualizing RDF datasets enhanced with geospatial Information.
map4rdf is an open source software. Just configure it to use your SPARQL endpoint and provide your users with a nice map-based visualization of your data. The geospatial aspects of the data can be modelled using either the data model from W3C Geo XG
