<br>
You can find a description of it here :<br>
<a class="moz-txt-link-freetext" href="http://www.3liz.com/blog/rldhont/index.php?post/2012/11/06/Spatial-operators-in-QGIS-expression">http://www.3liz.com/blog/rldhont/index.php?post/2012/11/06/Spatial-operators-in-QGIS-expression</a><br>
<br>
You can do this type of expression :<br>
intersects( $geometry, geomFromWKT( 'LINESTRING(765145.88
6274561.22, 776031.67 6284189.52)' ) )<br>
<br>
I made it for WFS QGIS-Server<br>

Hi all.<br>
In the Field Calculator there are, among the expressions, a
series of spatial<br>
operators (touches, intersects, etc.), but I cannot figure
out how to use them. They<br>
make sense as operators across layers, but I do not see how
to use them within the<br>
same layer.<br>
Any hint?<br>
Thanks.<br>
