Stuff near you in wikipedia
A while back I blogged about querying dbpedia with sparql. The queries in that blog were pretty simple. Today, I present a more complicated example.
SELECT ?a, ?long, ?lat WHERE {
http://dbpedia.org/resource/Borne%2C_Overijssel http://www.w3.org/2003/01/geo/wgs84_pos#long ?centerlong ;
http://www.w3.org/2003/01/geo/wgs84_pos#lat ?centerlat .
?a http://www.w3.org/2003/01/geo/wgs84_pos#long ?long ;
http://www.w3.org/2003/01/geo/wgs84_pos#lat ?lat .
FILTER ( -(?long - ?centerlong)(?long - ?centerlong) - (?lat - ?centerlat)(?lat - ?centerlat) > -0.01 )
}
This query gives you all items in the english Wikipedia near where I live.
You could also look for stuff near Gran Canaria or Berlin.
