I was thinking of a way to illustrate my opinion, somewhat complex using Ultra, but I realized that the best thing was to simply add the +Code grid to the OverPass-Turbo query.
https://grid.plus.codes/grid/wms/{z}/{x}/{y}.png
Both the grid and the +Code API default to 10 digits. But it is possible to extend the +Code up to 15 digits using the OLC documentation.
P.S. ULTRA
The large counts of Full_Plus_Code=6FWHW94V+P9PF and similar should just be removed, they are clearly a mistake. Probably by someone selecting all buildings, instead of a single one.
Full_Plus_Code is a bad idea and probably should be removed. But the ancient rule still stands, donât remove what you donât understand.
If Nominatim wants to make a political statement, they could support it in the same way they support querying by coords.
The OSM website should probably support them, as a special query, in the same way they support querying by coords. Maybe as a political statement, maybe for fun, maybe to support African mappers.
But mostly to annoy what3words.
Ok, so how can we do that? Who do we need to talk to?
