 wgs84_candidate(?URI, ?Point) is nondet
Finds URI-Shape pairs of RDF resources that are place-tagged with W3C WGS84 properties (i.e. lat, long, alt). Point = point(?Lat,?Long) ; Point = point(?Lat,?Long,?Alt).
 wgs84_candidate(?URI, ?Point, +Source) is nondet
Finds URI-Shape pairs of RDF resources that are place-tagged with W3C WGS84 properties (i.e. lat, long, alt). From RDF that was loaded from a certain Source.
 lat(?URI, ?Lat) is nondet
Finds the WGS84 latitude of resource URI (and vice versa) using the rdf_db index. Lat is a number.
 long(?URI, ?Long) is nondet
Finds the WGS84 longitude of resource URI (and vice versa) using the rdf_db index. Long is a number.
 alt(?URI, ?Alt) is nondet
Finds the WGS84 altitude of resource URI (and vice versa) using the rdf_db index. Alt is a number.
 coordinates(?URI, ?Lat, ?Long) is nondet
 coordinates(?URI, ?Lat, ?Long, ?Alt) is nondet
Finds the WGS84 latitude, longitude and possibly altitude of resource URI (and vice versa) using the rdf_db index. Lat, Long, and Alt are numbers.
 coordinates(?URI, ?Lat, ?Long) is nondet
 coordinates(?URI, ?Lat, ?Long, ?Alt) is nondet
Finds the WGS84 latitude, longitude and possibly altitude of resource URI (and vice versa) using the rdf_db index. Lat, Long, and Alt are numbers.
