Submarine-Cable Jurisdiction Trace
The physical internet has a geopolitics. This traces a submarine cable's route — where it lands and every sovereign jurisdiction the wire crosses — and flags the high-interception or sanctioned territories along the way. For anyone weighing the geopolitical and interception risk of how data physically travels.

Why each step runs
- 01Cable landings. Walks CABLE_LANDS_AT to list every CABLE_LANDING this cable terminates at — the city/country/lat-long that defines where the wire physically touches land.
- 02Transit-jurisdiction exposure set. Collapses landings to the distinct set of sovereign countries — the states that sit on the physical path and can tap, interdict or sever the link.
- 03High-interception / sanctioned landings. Intersects the jurisdiction set with the watch list to surface landing countries with elevated interception or sanctions risk on this physical route.
- 04Co-landing chokepoint density. For each jurisdiction on the path, counts the other submarine cables that also land there — physical chokepoints where one sovereign sits astride many links at once.
