我运行这个查询:
PREFIX geo: <http://www.opengis.net/ont/geosparql#>
PREFIX geof: <http://www.opengis.net/def/function/geosparql/>
select *
where
{
?x <http://www.opengis.net/ont/geosparql#hasGeometry> ?fGeom .
?fGeom geo:asWKT ?fWKT .
FILTER (geof:sfWithin(
'<http://www.opengis.net/def/crs/EPSG/0/27572>
Point (729326 2521619) '^^geo:wktLiteral,
?fWKT))
}
针对 GraphDB:
<http://data.edf.fr/departements/dep_france_dom/Geometry/2> a <http://www.opengis.net/ont/geosparql#Geometry> ;
<http://www.opengis.net/ont/geosparql#asWKT> "
<http://www.opengis.net/def/crs/EPSG/0/27572> MULTIPOLYGON (((729326 2521619,....
在商店里,我没有得到任何结果。你认为这是由于“法国异国情调”CRS吗?
