Working with geojson viewer

Geographic data uses coordinate order, units and reference systems to describe locations. Files that look similar can use different conventions, so a successful parse alone does not establish that points are in the right place.

Common questions

Why do points appear in the wrong country?

Swapped coordinate order, incompatible reference systems or wrong units can shift points dramatically. Test a location whose expected position is known.

Does conversion improve location accuracy?

No. A format conversion preserves or transforms the supplied data; it does not make the original measurement more precise.
