Hi Michael,
In line with Harrissou's advice, yesterday I tweeted [1] about an extension
to the "Overlap analysis" in QGIS, which works on exactly 2 layers and is
called "Overlap analysis by class".
The outputs are both overlap area and percentage per class. Perhaps it
could help you.
See
Hi,
A starting point can also be the Processing "overlaps analysis" algorithm [0]
(sorry I don't know how the output actually looks like) followed by some
aggregate analysis.

I am sure this is easy but I can't work out which facility to use
I have two layers. Layer A is made up of some large polygons while Layer B
is made up of smaller polygons. The Polygons in Layer A overlap one or more
of the polygons in layer B. In most cases the overlap is 100% but there are

Hi,
I have a PostgreSql stored procedure which returns a geojson feature
collection created with json_build_object function.
This web service opens fine in OpenLayers, however, when I try to open
it in QGIS, with data source manager -> vector -> protocol -> geojson :

Hi Mike,
I can ensure you I installed QGIS on various PCs (Win10 and WIN11) within less
than 90mins using latest OSGeo4W installer having 50mBit/s Downstream 10Mbit/s
Upstream and from local German norbit.de mirror. From osgeo.org it takes about
2hrs. Same on Win7 but a while ago. Having enough
Salve
mi hanno fatto comodo le vostre osservazioni, in particolare che lo
statement return provoca l'uscita da ogni loop.
Ho risolto mettendo i risultati che uscivano ad ogni loop da
processing.run('qgis:rastercalculator'...
in una lista (myList) e alla fine
return {self.OUTPUT: myList}
Grazie

si, certo.
Hi,
I'm coming in late to this methodology discussion, so apologies if I am
off the mark.
So by 'center line' I'm guessing you mean a line that is always
equidistant from the polygon boundary.
I had a similar problem a few years back where I had to create road
center lines from a polygon
Hi Kirk,
Yes, that worked well. I added the code from the processing toolbox and
it worked fine.
Very helpful, thanks very much . . . .
