Hi everyone,
This question is related to Virtuoso geometry functions, RDF_GEO_FILL(),
which will create geometry index based on (latitude, longitude) properties.
However, according to the documentation (
http://docs.openlinksw.com/virtuoso/rdfsparqlgeospat.html#rdfsparqlgeospatcrg),
this function will be
inefficient if there are large numbers of geometries. That is the problem
we are facing now. I wonder if there is a way to execute this function on
specific graph so we can limit the number of triples this function has to
read through?
If that is not possible, is that OK if I manually create the "geo:geometry"
property for the data before inserting it into Virtuoso?
Best Regards,
Hoan
