the problem is that the lat long import from wikidata doesn t round when converting from dms to dec so we can not infer the dms precision from the number I just refactored to use module geobox coor which has a hack to round the imported numbers if lats longs 0 the better fix would be to have the module that converts the dms to dec not return excessively precise numbers once we have that I can remove the hack from module geobox coor
