[Qgis-developer] Spatial operators in field calc

[rldhont]

Hi Paolo,

You can find a description of it here :
http://www.3liz.com/blog/rldhont/index.php?post/2012/11/06/Spatial-operators-in-QGIS-expression

You can do this type of expression :
intersects( $geometry, geomFromWKT( 'LINESTRING(765145.88 6274561.22, 
776031.67 6284189.52)' ) )

I made it for WFS QGIS-Server

Regards,
René-Luc D'Hont
