Underground/submarines cables - are they correctly shown?
Zapsal Obelixx 20. 12. 2011 v jazyce English.I discovered that several underground/submarine cables are shown in Openstreetmap. Which were the sources of their track? As on satellite pictures it is in most cases impossible to find out where they run and that they are not shown in most maps commercial available, it may be impossible to proof if a shown way of right is correct. Which are the used data for such objects? How exactly is their track shown?
Diskuse

What does the source tag say? Does the changeset have a comment or a source tag? If not send a message to the uploader asking for a source.

There was a discussion a while ago on the talk mailing list about submarine cables:
http://lists.openstreetmap.org/pipermail/talk/2011-October/060413.html
But I pointed out in the next message that this particular source did not appear to be suitable for OSM (license issues aside).
But maybe someone found another source. Not sure this is really OSM suitable data though. As you point out, it is pretty much impossible to verify the route except for short sections at the shore.
