Hibernia Atlantic dublin landing station is a good example.So 100% of those beach manholes are watertight and safe from flooding, and don't contain any gear that will get upset if it does in fact end up with salt water in there? This listing for landing points in Japan seems to call out a hell of a lot of specific buildings that are nowhere near 10 to 30 km inland: https://www.google.com/maps/d/viewer?mid=1Siy5qBMoFyBUlSFNHdHDpGAkIR0 Singapore: Right on the water. http://www.streetdirectory.com/sg/singapore-cable-landing-station/1-changi-north-rise-498817/8118_79569.html Hong Kong: More of same (though with its hills, some of the 8 sites may actually be a bit above sea level even though they're 2 blocks from water) http://www.ofca.gov.hk/en/industry_focus/telecommunications/facility_based/infrastructures/submarine_cables/index.html Cryptome has a bunch of older images that tend to indicate that a lot of buildings right on the water in New Jersey and Long Island are involved: https://cryptome.org/eyeball/cable/cable-eyeball.htm And that's just in the first 3 pages returned by Google for "cable landing station map". The experience of the Manhattan phone system when the conduits and basements flooded during Sandy tends to indicate that we *are* in for similar surprises over the coming decades.
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. -Hank
