Recently we have seen a large increase in the amount of geospatial data that is being published using RDF and Linked Data principles. 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, visualizing and interacting with RDF datasets enhanced with geospatial information.
Configure Map4RDF 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 or the geometrical data model proposed by GeoLinkedData
- Faceted browser interface.
- Geospatial and geometrical visualization using Google Maps, Open Street Maps and national spatial data infrastructures.
- Visualization of GeoSPARQL WKT geometries (LineStrings, Polygons, etc).
- Visualization of statistical data using DataCube.
- Editing and storing displayed data in RDF data format.
- Query Filtering.
- Easy configuration via an admin panel or a configuration file.
You can see several deployments of Map4RDF (these sites will be experiencing continuous transformations as we progrees with the development). Some examples are:
There are also external projects that are already using Map4RDF, such as the Ecuadorial Linked Geospatial Data initiative (URL soon to be added).
We are working on providing a simpler configuration description and tools, but for the time being you can use this PDF
