I was hoping that non-terrestrial coordinates would be allowed with this
change, but it appears not.

Hi Pasquale,

The new GeoSPARQL feature is in the git develop/7 branch for which prebuilt 
binaries are not available and would thus have to be compiled from:

Hi Ghislain,
many thanks for your answer.
By the way the page you're mentioning doesn't resolv my doubts.

First the last two examples, which are using geospatial query
(bif:st_intersects) are not working: the first is giving no results, the
last an error.

Then I'm concerned with the geospatial functions. E.g. bif:st_intersect is
defined in an openlink ontology (http://www.openlinksw.com/schemas/bif#)
and are based as far as I can see on SQL MM.
The GeoSPARQL functions are defined here:
http://www.opengis.net/def/function/geosparql/. The GeoSPARQL function for
intersect is http://www.opengis.net/def/function/geosparql/sfIntersects

I don't understand if these GeoSPARQL functions are supported by Virtuoso.


Pasquale

Hi Pasquale,
Yes, I think you are missing something. The point is probably that you are not 
using quite well the functions in your queries?! 
Please have a look at this page 
http://linkedgeodata.org/GADM which contains some sample queries for the 
LinkedGeo data endpoint which powered by Virtuoso.

Re: [Virtuoso-users] GeoSparql: Filter by rectangular area/bounding box

2011-01-11 Thread Hugh Williams 
Hi Claus,

There is currently only support for geo POINT data in Virtuoso  Commercial 
Edition and this feature is not supported in the open source release at all.

We have already drawn up some plans to add other types like LINES,  POLYGON 
etc, but we have not yet had sufficient feedback or commercial  incentive to 
move it more to the front of our development queue.

However given the right signals from the marketplace we can certainly  
re-prioritize this effort.

Hugh Williams
