Hi Kingsley, Yes, geo capabilities work very well under Virtuoso Cloud Edition (good performance was a great surprise after migrating from lod.openlinksw.com to custom Amazon EC2 instance). Here I will quote the initial question to point out the problem:
"Prevously I executed LGD queries using lod.openlinksw.com endpoint (where full LGD is loaded). Today I have loaded LGD Elements to my custom Virtuoso instance and all LGD queries became broken. As I have found out "geometry" predicate is absent at LGD Elements dataset. Changing "geometry" to combination of "lat" and "long" solved my problem. But please put the note concerning "geometry" predicate at linkedgeodata.org/datasets page to prevent other people to struggle with this problem."
