Re: [Virtuoso-users] Geometric Objects

Hi Hugh, Thanks, so, if I understand you correctly, for the moment, I cannot import generic 2d Cartesian coordinate data into a spatial index? - Erich On 05/30/14 11:22 PM, Hugh Williams wrote: > Hi Erich, > > The st_setsrid() function sets the SRID but does not project the coordinates >

Re: [Virtuoso-users] Geometric Objects

Hi Erich, The st_setsrid() function sets the SRID but does not project the coordinates as it doesn't have to make the projection. PostGIS works same way, see: http://postgis.net/docs/ST_SetSRID.html The purpose of the st_setsrid() function is to set the SRID on a geometry to a particul

Re: [Virtuoso-users] Geometric Objects

Hi Hugh, Stupid me on forgetting the double braces. How can I change the default srid from 4326 to something else? I just want a 2d Cartesian coordinate system (my data isn't WGS 84). Although it seems I can change the srid with st_setsrid, ttlp will throw the same error as below when

Re: [Virtuoso-users] Geometric Objects

Hi Erich, You need to have double opening and closing braces around the "POLYGON((...))" geometry type: Fails: SQL> ttlp ('@prefix virtrdf: . @prefix geo: . _:wow geo:geometry "POLYGON(1 2, 6 1, 9 3, 3 6,

Hi Hugh, Awesome! However, I tried adding a single triple as follows and got an error. Am I missing something? SQL> ttlp ('@prefix virtrdf: . @prefix geo: . _:wow geo:geometry "POLYGON(1 2, 6 1, 9 3,

Re: [Virtuoso-users] Geometric Objects

Hi Erich, Virtuoso open source and commercial does now have support for polygon geometry types and others as detailed on the 7.1 release notes at: http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VOSNews#2014-02-17%20--%20Virtuoso%20Open-Source%20Edition%207.1.0%20Released Li

[Virtuoso-users] Geometric Objects

Are there any plans to support other geometries like POLYGON besides POINT in Virtuoso? As per, "9.34.3. Geometric Objects - Only the 2D point is supported." at the URL: http://docs.openlinksw.com/virtuoso/sqlrefgeospatial.html - Erich
