Nonacademic reference grids A, B, C, 1, 2, 3... are hardly zoomable, so they
got unused. Consequently, the State of the Map is a Naked Emperor:

no grid at all (!)

and the answer to the question "where?" is "here!"

This unworthy situation caused the proliferation of enigmatic location codes,
some based on names (!?)

A simple standard circle and the rebirth of the Time/Space Convention *)
will upgrade the State of the Map, create imaginable location codes, help to
avoid confusions etc. etc..
