Hi Sebastien,<br>
AFAIK, you don't need to dissolve the polygons before using them as <br>
input of the "Random points in layer bounds" algorithm: such algorithm <br>
correctly places the total chosen number n of random points even if the <br>
input N features/polygons are not dissolved.<br><br></blockquote><div>I believe I was the one who suggested the layer bounds approach.<br></div><div><br></div><div>Thomas Sebastian, you do not need to dissolve the polygons if you are only interested in placing the random points within the layer bounds as Andrea says. If you have a non-rectangular dataset then your layer bounds could result in points being placed outside the polygons in your dataset; you should do the dissolve and place the points within the dissolved polygon. If like me you live in a rectangular / map-sheet-ish world then by all means work in the layer bounds.<br></div></div><br clear="all"><br><span class="gmail_signature_prefix">-- </span><br><div dir="ltr" class="gmail_signature"><div dir="ltr">Chris Hermansen · clhermansen "at" gmail "dot" com<br><br>C'est ma façon de parler.</div></div></div>
