A SPARQL query to map category A & B listed road and rail bridges in Scotland:
SELECT DISTINCT (?showLabel as ?layer) ?loc ?pic ?picLabel ?picURI ?herlistLabel ?cooncilLabel WHERE
{
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
VALUES ?itemtypes { wd:Q12280 wd:Q537127 wd:Q1210334 }
?pic wdt:P31 ?itemtypes.
?pic wdt:P131 ?cooncil.
{ ?cooncil wdt:P131 wd:Q22} UNION {?cooncil wdt:P31 wd:Q15060255.}.
?pic wdt:P625 ?loc .
?pic wdt:P31 ?itype.
?itype rdfs:label ?itypeLabel.
FILTER(LANG(?itypeLabel) = "en").
FILTER (?itype = ?itemtypes).
OPTIONAL {?pic wdt:P18 ?picURI.}.
?pic wdt:P1435 ?herlist.
FILTER (?herlist != wd:Q10729142).
BIND (IF (BOUND(?picURI), ?itypeLabel, CONCAT ("Unimaged ", ?itypeLabel)) AS ?showLabel).
} LIMIT 2000
While the filtered mapping might be useful to identify unphotographed bridges, the map overall is too crowded to be particularly useful.
