2014 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.

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.


AKSW at TU Dresden PLT
On June 8, I (Jens) visited the process control engineering research group (PLT) of Leon Urbas at the Dresden University of Technology. We first met on the Leipziger Semantic Web Day where Leon Urbas presented interactive Linked Data applications and decided to have a longer meeting later on. I first gave a talk on the [...]

LinkedGeoData Release 2
The AKSW research group is happy to announce a new release of LinkedGeoData! The aim of the LinkedGeoData (LGD) project is to make the OpenStreetMap (OSM) datasets easily available as RDF. As such the main target audience is the Semantic Web community, however it may turn out to be useful to a much larger audience. [...]

May 4-5: Leipziger Semantic Web Tag 2011 and Local Media Conferenz
Like in the past two years, we again organize a Leipzig Semantic Web Day on May 5th at the marvelous Mediencampus Villa Ida. This year’s theme is “Linked Data¬† for the Masses”, particularly focusing on its use in enterprises. This event will not only give you the opportunity to discuss current developments around semantic web [...]

The Linked Geo Data 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 1 billion nodes and 100 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.

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.

Sep 24 There is still an issue with the Sparqlify servlet stopping to respond with message “Max Server Threads reached”.
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
July 23 About 30min offline because of server restart
July 5 Website online again, after a crash of My SQL
June 30 Server was swapping – reduced buffer sizes of the DBs 
June 27 Short downtime due to Open Link's Virtuoso licence upgrade
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.
