No, reference only says where the data comes from, best case - when it was retrieved (vast majority now doesn't have that either). But no guarantee it is still true with claimed precision. > I can't think of anything really useful right now...

Indeed, if the precision is too low, there is danger, but from what I understood (my Czech is kinda weak ;) the grids there are also because of some data representation artifact. -- Stas Malyshev [email protected] _______________________________________________ Wikidata mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikidata
