Title Body

Wikipedia is geotagging a lot of its articles . (Look in the top right corner of the page.) Is there any API for querying all geotagged pages within a specified radius of a geographical position? Update Okay, so based on lost-theory's answer I tried this (on DBpedia query explorer ): PREFIX geo: <http://www.w3.org/2003/01/geo/wgs84_pos#> SELECT ?subject ?label ?lat ?long WHERE { ?subject geo:lat ?lat. ?subject geo:long ?long. ?subject rdfs:label ?label. FILTER(xsd:float(?lat) - 57.03185 <= 0.05 && 57.03185 - xsd:float(?lat) <= 0.05 && xsd:float(?long) - 9.94513 <= 0.05 && 9.94513 - xsd:float(?long) <= 0.05 && lang(?label) = "en" ). } LIMIT 20 This is very close to what I want, except it returns results within a ( local ) square around the point and not a circle. Also I would like if the results where sorted based on the distance from the point. (If possible.) Update 2 I am trying to determine the euclidean distance as an approximation of the true distance, But I am having trouble on squaring a number in SPARQL. ( Question opened here .) When I g
