Relocation keeps the birth instant fixed while changing the terrestrial viewpoint. The planetary positions remain those of the moment; the local horizon and meridian change.
Astrocartography gathers the angular conditions of all those possible viewpoints onto one earth. A line is the locus of places where one body is rising, setting, culminating, or anti-culminating at the original instant.
A relocated chart can sharpen a question about place, but it cannot supply evidence about housing, work, health, safety, or relationships on its own.
