Online Access

Overview

The following interfaces exist for online access:

• Rest Api: provides basic access to a database with a full Open Street Map (OSM) planet file loaded.
• Sparql Endpoints: enable queries on databases with a reduced (but hopefully for many applications relevant) subset of the whole data loaded. The Sparql Endpoints come in two flavours:
  • Static: Contains the data extracted from a OSM planet file of a certain date
  • Live: Initially a copy of the static version that is then synchronized with the minutely updates from OSM.

A summary of the capabilities of the interfaces are given below. Click the above links for the detailed documentation and the Sparql Endpoints, respectively.

REST API

Features

• Access to all nodes and ways and their tags of a planet file.
• Supports content negotiation
• Retrieval of RDF data for individual nodes and ways

• Retrieval of data within circular and rectangular area

http://linkedgeodata.org/api/3/intersects/51.033333,13.733333/1/class/Amenity (1km radius around given point)
http://linkedgeodata.org/api/3/intersects/51.02–51.04,13.72–13.74/class/University

• Note: the underlying database is being synchronised with OSM. View http://linkedgeodata.org/api/3/recent for recent updates.

Sparql Endpoints

Flavours

• Static: Contains the data extracted from a OSM planet file of a certain date
• Live: Initially a copy of the static version that is then synchronised with the minutely

Features

• Full Virtuoso SPARQL query capabilities
• Access to > 220mio triples
• Static and live versions

Drawbacks

• Entities and tags undergo a filtering procedure (explained here), therefore not all available OSM data is being loaded into the store.
