Dear List,
does anyone have some observation how long does it take for a reported bug to
be fixed?
I reported a serious regression in April, but it’s not fixed yet.

Hi
Hello,
I am trying to figure out the duration between one day's survey begin time
(e.g., 7:13:45) and end time (e.g., 9:39:53) in an attribute table of a line
shape file. It has just two attributes begin and end. But $lengh returns an
error message and cannot figure out the duration. I suspect

Salve, stavo oggi cercando una cosa per me, e mi pare che questa funzione sia
giá presente nel core.
Quando scegli VALUE RELATION come widget, in basso si apre il filtro, e
nelle funzioni FORM trovi la current_value

Hi,
I see you have been pointed to the semi automatic classification plugin. Note
that Google Earth is not usable for such work unless you simply want to make a
visual identification. Landsat can be used. You should look at various peer
review papers if you want to make a good job. This is
The layer being multilinestring just mean that you can create features with
multi geometries in it. It says nothing about the actual features in it.

Hello all:
Just to complete this thread, I have been working for some months now
with QGIS 3.8 on Debian 10 running Gnome under X.org (NOT the default
Wayland). And there have been no issues, no slowdowns, no crashes.
Today, just to test again, I switched back to Gnome under Wayland, and

Hi list,
I've got a project set up in QGIS 3.4.x with a parent polygon layer and a child
attribute layer. Each site polygon represents a piece of land and can have
multiple tasks associated with it (grass cutting, weeding, pruning, etc.).
Sites can be made up of multiple polygons.

Buongiorno a tutti,
che voi sappiate esiste un metodo per creare, a partire da un gruppo A, n
sottogruppi in automatico?
Il risultato che vorrei ottenere è il seguente:
GRUPPO A
sottogruppo 1
sottogruppo 2
sottogruppo 3
Lo chiedo perché ho la necessità di crearne in gran numero in tempo
Hi,
Can you provide a sample of your data?
What version of QGIS are you using? What OS?

Hello,
In my project I need to compare the result of the concatenation of two
fields, A and B, in common between two different layers.
For he moment, I'm using a calculated field in each layer to concatenate
the two fields. Then a sql request in a virtual layer compare them.
