Work with worldwide vector data in Python without a single projected CRS to hide behind: audit a gazetteer against its own geometry, measure nearest-neighbour distances geodesically, and write clip-and-aggregate scripts in an equal-area projection that a reviewer can re-run.
Natural Earth as a working dataset rather than a backdrop: geodesic distance across a planet, clip-and-credit overlays in an equal-area projection, and the audit that decides whether a reference file can be trusted at all.
