TASK DESCRIPTION
  `wikibase:geoPrecision` is used in `pqv:P625` (a 
`wikibase:GlobecoordinateValue`). 
  It's  defined as 
<https://en.wikibooks.org/wiki/SPARQL/WIKIDATA_Precision,_Units_and_Coordinates>
 "precision of the coordinate values, measured in degrees. Multiply by 111000 
to convert to meters".
  As far as I can see, there's no way to set it from the UI so I assumed it's 
calculated from some rule, eg "If there is a street address, set 30.8m".
  
  - Eg for Volkswagen Group <https://www.wikidata.org/wiki/Q156578#P159> that 
has a street number, the precision is 30.8m. Sounds reasonable, that may be a 
long building.

        wikibase:geoPrecision "0.00027777777777778"^^xsd:double ;
  
  
  
  - But eg for Muzeum gastronomie in Prague 
<https://www.wikidata.org/wiki/Q15735270#P159> that has street **and 
conscription** (building) number, the precision is 1554m, why?
