It identifies terrestrial optical fibre cables going underground
between cities in France.
How should it be mapped in OSM ?
Those cables are not visible and therefore should not be mapped.
Being in charge of GIS projects for the fiber network of a major
telecommunication operator, my opinion is that Openstreetmap will never
achieve any useful view of optical networks: those cables are everywhere
but their path is usually not visible from public right of ways.
I contribute to the mapping of high-voltage lines, which are major
landmarks. I support the mapping of cabinets, which are minor urban
landmarks. I understand that some may be willing to map
telecommunications chambers, whose metal opening is visible on the
surface. But spare yourself the pain of mapping underground cables - I
guarantee it is a hopeless and useless endeavour.
