LinkedGeoData is an effort to add a spatial dimension to the Web of Data / Semantic Web. LinkedGeoData uses the information collected by the OpenStreetMap project and makes it available as an RDF knowledge base according to the Linked Data principles. It interlinks this data with other knowledge bases in the Linking Open Data initiative.

The LinkedGeoData Knowledge Base

In order to employ the Web as a medium for data and information integration, comprehensive datasets and vocabularies are required as they enable the disambiguation and alignment of other data and information. Many real-life information integration and aggregation tasks are impossible without comprehensive background knowledge related to spatial features of the ways, structures and landscapes surrounding us.

LinkedGeoData uses the comprehensive OpenStreetMap spatial data collection to create a large spatial knowledge base. It consists of more than 3 billion nodes and 300 million ways and the resulting RDF data comprises approximately 20 billion triples. The data is available according to the Linked Data principles and interlinked with DBpedia and Geo Names.

Wiki Contents

This Wiki provides information about the LinkedGeoData community project:

  • Datasets gives an overview about the LinkedGeoData knowledge base and allows to download the whole dataset.
  • Online Access describes how the data set can be accessed via Linked Data.
  • Use Cases lists different LinkedGeoData use cases.
  • Publications gives an overview about LinkedGeoData related publications.
  • Community explains how the LinkedGeoData community collaborates and how people can contribute to the effort.

May 7 Linked Data interface operation back to normal
May 7 Linked Data interface back to normal after multiple faults and regressions due to moving and upgrading services
Feb 3 SPARQL Endpoint and Linked Data operation back to normal
Jan 27 Service temporary down due physically moving the server to a new location.
Nov 21 Database back online. Enjoy!
Nov 15 Due to a database upgrade we need to reload the data – REST API estimated to be back online around end of the week
Jan 13 New Open Street Map RDF datasets available online and for download!
Sept 21 Completed upgrade to Postgres 9.3 and loaded a fresh LGD database. Please create issues in the git should you experience any problems. New downloads are in the works.
Sept 18 LGD REST-API was down due to long overdue hard- and software upgrades. The SPARQL endpoint was unaffected.
May 13 New datasets for download available here! Data in the SPARQL endpoint will be updated later.
Mar 31 The LinkedGeoData repository moved to GitHub. Look there how you can now convert the data you want yourself!
Apr 5 LinkedGeoData may be temporarily down tonight due to maintenance.
Mar 31 The LinkedGeoData repository moved to GitHub. Look there how you can now convert the data you want yourself!
Sep 10 Servers are back online after being down for the week because of moving them to a new location. Also, updated licence statements to ODbL, because we are required to do so – at least according to the OSM wiki
June 12 Added a missing index on the way_tags table
June 11 Deployed REST API under http://linkedgeodata.org/api/3/*. Updated examples on the website. More tuning for performance needed.
