Dear All, I tried to execute the following spatial join query on Jena 2.13.0. Here, the distance between place ?long and another place ?nlong should be less than 10,000 meters?
./tdbquery --time --loc=spatialTestDatabase/ "select ?place ?nplace ?type ?subject (<http://www.opengis.net/def/function/geosparql/distance>(?long, ?nlong, 10000) as ?distance) WHERE {graph ?g1{?place <http://www.opengis.net/ont/geosparql#asWKT> ?long} graph ?g4{?nplace <http://www.opengis.net/ont/geosparql#asWKT> ?nlong}}"; On running the above query, I ended up getting the following error: 16:44:00 WARN exec :: URI <http://www.opengis.net/def/function/geosparql/distance> has no registered function factory Can someone please help me as to where am I going wrong?
