- 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.
