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.
