Is it possible to create using RDF a relationship between points (Latitude/Longitude) such that when loaded into a store (such as Jena Fuseki with the GeoSPARQL extension) that the distance between points will be inferred, e.g. in kilometers?
Otherwise, in order to determine the distance between points and add it to the triple store, I imagine that a query would be necessary for each point (and/or a query with a subquery to essentially to run a query for all points in a single query). Does this sound correct?
Ideally, the solution is fast as there could be millions of points. For example, I tried measuring 600,000 points to 9,000 linestrings (600k x 9k comparisons) in Jena GeoSPARL Fuseki and each comparison was taking roughly 10 seconds.
