Re: [Virtuoso-users] Geospatial query

2017-03-08 Thread Pasquale Di Donato 
Hi Hugh,

we are publishing administrative units and use case is "Give me the admin
unit @POINT". That's clear that @POINT there is only one administrative
units of a specific type.
E.g. with the following query I'm asking the admin unit "Canton" @POINT:

https://tinyurl.com/z24uapm

Then I get one resource: correct.

Same query at another point, but returning 2 resources as a consequence of
the fact that st_contains uses BBOX: not correct for me

Ciao
Pasquale

Hi 

Yes, the st_contains functions does work within a bounded box as detailed at:


https://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtGeoSPARQLEnhancementDocs#Virtuoso
 Geo Spatial geometry functions 


Why is this a problem for you, do you have a test case to demonstrate ?
