<div>I had noticed the polygons to points converter, but wanted to
do it "properly" - i.e. with a polygons in polygons comparison.</div>
<div><br>
</div>
<div>Your method will likely work but adds two extra steps
(conversion to points and then from points back to polygons).
Does QGIS not have a tool for this then?</div>

<div>Thanks!</div>

<div>Here's how I would do it: You have Two polygon layers
and you need to count the number of polygons in layer 1
that are contained in the polygons in layer 2 <br>
<br>
1. Convert the polygons in 1 to points: Vector ->
geometry -> polygon centroids <br>
2. then use -> vector -> analysis tools ->
points in polygon. Count the number of points contained
by polygons in layer 2. <br>
<br>
Hope that helps or at least creates an idea. <br>

<div class="h5">Hi List,
<div> I have two layers of polygons. I want to do
some analysis between them, basically doing a
spatial join, counting how many of one polygon
layer there are intersecting with each polygon in
the other layer. </div>
<div>ArcGIS does this easily with the "Spatial Join"
tool (ArcToolbox version). How can I do this in
QGIS?</div>
<div><br>
</div>
<div>I know there is Vector -> Data Manage Tools
-> Join attributes by location, but that only
acts as a basic join and doesn't allow for
counting of the number of joins.</div>
<div><br>
</div>
<div>Sextante has a large collection of tools, but
none of them seem to have any help so I don't know
what any of them do. (And none of them seem
applicable anyway).</div>

<div>Suggestions welcome, Cheers,</div>
