 ( predicate longitude latitude  )
 Converts longitude,latitude into a point using predicate to find the geospatial mapping. 
For example:
prefix geofn: <http://franz.com/ns/allegrograph/3.0/geospatial/fn/>
select ?point {
   bind(geofn:toPointLonLat(<http://ex#predicate>, 34.0, 30.0) as ?point )
 }    Note the argument order to the function is  longitude ,  latitude  to match the 2D geospatial conventions. 
 If either  longitude  or  latitude  is outside the range for the mapping, then the point will remain unbound.
