Location of subscriber (NRA) and optical (NRO) connection nodes in OpenStreetMap

Daily extract of the connection nodes subscribers (NRA) and optical (NRO) in metropolitan France present in the OpenStreetMap (OSM) open and collaborative database [1].

The layer is available in MAGOSM
— accessible via public WMS and WFS services
— viewable, searchable and downloadable via the carto portal
— analysable over the last 30 days via the Change Tracking Portal

Data model
The OSM attributes used to filter the data are:

• Telecom =exchange
• Telecom =central_office
• man_made=telephone_office

We find in the layer all the objects concerned whether they are mapped in the form of a node, path or relationship in OSM. For polygons and multi-polygons, the geometry provided corresponds to the centroid, the original geometry is available in EWKT format via the attribute ‘osm_original_geom’ and the original type in a column ‘osm_type’.

Additional OSM attributes have been selected to enrich the main tags.
All attributes prefixed by “osm” (e.g. osm_user, osm_id...) are common properties similar to meta-data on the OSM object.

More information about:

• the ** hospital-specific data model** on the OSM Wiki page — EN:Tag:telecom=exchange [2]
• the general OSM data model is documented on the OSM Wiki page — Map Elements [3].
• the modes and frequencies of use and combination of different attributes within the OSM community on the TagInfo France service [4]
