Store website regular expression: /^https:\/\/www\.tesco\.com\/store-locator\/uk\/\?b(?:id|ID)=([1-9][0-9]*)$/

Branches not matched to OSM (32)

Branches of the store that are contained in the source data, but that have not been matched to an OSM object. This could be becuase the OSM object is missing or misplaced, or that it lacks the correct brand:wikidata tag, or that there is an incorrect location in the source data.

OSM Objects not matched to list (2)

OSM objects with a brand:wikidata tag that have not been matched to a branch in the source data. This could be because a former branch has now closed, the brand:wikidata is incorrect, there are duplicate OSM objects for the same branch, or because of a location error in the source data.

Duplicate Matches (12)

OSM objects not matched initially, but which are within 500m of a matched store, and share the same website tag. These could be errors, or they could be legitimately tagged petrol station shops attached to a larger store.

Matched Branches (225)

OSM objects with a brand:wikidata tag that have been matched to a branch in the source data. Postcode matches are accepted at any distance, otherwise the locations must be sufficiently close.
