OSM Planet SPARQL Endpoints

This page compares the different SPARQL endpoints available for querying OpenStreetMap (OSM) data.

Configuration for pylodstorage sparqlquery tool

see https://pypi.org/project/pyLodStorage/

installation

pip install pylodstorage

The configuration files need to be in $HOME/.pylodstorage or you have to explicitly give the path with the -ep and -qp options

endpoints.yaml

osm-sophox:

  endpoint: osm-qlever
  param_list:
    - name: relid
      type: str
      default_value: "6843452"
  sparql: |
    # Get statistics about predicates used in an OSM relation 
    SELECT ?p (COUNT(?o) as ?count)
    WHERE {

    }
    GROUP BY ?p
    HAVING (?count > 1)
