I think you are missing the point. The issue is not the actual landing
station but the actual *exact *path the cable takes from 100meter out at
sea to the landing station. For that you need GPS coordinates down to a
3' level as the fiber snakes its way from shore into the city. I do
not believe that is available on the Internet and is only available to
the actual company that laid the cable. One can try to deduce the path
by looking for manhole covers but that would require opening and
physically inspecting.
