    Why do you think they expect it to be permanent? We survey all kinds of stuff like this all the time.

      Geography and celestial maps are permanent (mostly).

      The next question is, how long until a quantum measured map becomes unrecognised? Is the half life years or hours?

        There’s literally whole projects to map out movements of continents and the change of the geoid shape of earth, although it takes a few years for it to matter in most cases

          Unless there is volcanic activity, geography can be considered permanent within a lifetime. Given the accuracy this technology claims, I suspect the lifespan is very short lived.
