[Qgis-user] Qgis 3.6 problem

[Jukka]

Hi,
I have two version of Qgis, 3,6 and 2.18. In  both version I have problems. I 
started a new project and if I add raster layer map and vector layer on map, I 
only can see the map or vector layer, not both. But I have older projects that 
works allright. What is the problem?

[Qgis-user] r.viewshed batch processing

[Samuel Williams]

Hello,
I'm having some difficulty running the G.R.A.S.S r.viewshed tool in batch
mode from QGIS. Everything runs fine when initiated via the single run
interface, but switching to batch mode and entering the same parameters
fails - it looks like a parameter isn't being sent to G.R.A.S.S correctly.
If anyone can see why it is failing I would be most grateful for any
suggestions!

Ciao Martina,
secondo me dovresti fare al contrario, cioè:

aggregate( layer:='id layer_punti', aggregate:='concatenate',
expression:="DENOMINAZIONE", filter:=intersects (  transform(  $geometry ,
'EPSG:4326', 'EPSG:32632' ) ,  geometry( @parent)), concatenator:=', ')

facci sapere

Re: [QGIS-it-user] Funzione "aggregate" con variabile @parent su layer con SR diversi

[Martina Savarese]

Mmh, non mi ha funzionato :(
cioè il calcolatore non mi dà errori, ma mi restituisce tutti valori nulli
sul campo virtuale, proprio come faceva senza usare transform.
Sul layer poligonale dei comuni (EPSG 32632) ho usato l'espressione:
aggregate( layer:='id layer_punti', aggregate:='concatenate',
expression:="DENOMINAZIONE", filter:=intersects (  transform(  $geometry ,
'EPSG:32632', 'EPSG:4326' ) ,  geometry( @parent)), concatenator:=', ')
dove 'id layer_punti' è l'id di tale layer (che ha EPSG 4326)

Alla fine ho riproittato il layer dei comuni in 4326 e ottenuto il campo
virtuale che volevo (riproiettare l'altro sarebbe stato un casino per come
avevo già impostatoil progetto) però mi avrebbe fatto più comodo mantenerlo
in un sistema proiettato.

Comunque grazie per la dritta,
Martina

Can you try to search in the project file?
It's 'just' a zip, so rename unpack it and search for IE or explorer in the 
.qgs xml file

[Groene Bij]

Update 2:
Opening a specific project and making a qgis2web export again opened IE.
Starting a new project and exporting in qgis2web opens Firefox.

So, choice of browser is somehow linked to the project.
This does not explain why any new project also used to open IE, until I used 
the python console command suggested by Richard.

Strange indeed.

Short update on this issue.

After entering QDesktopServices.openUrl(QUrl('http://qgis.org')) and seeing 
qgis3 opening the firefox browser, now qgis2web also always opens the firefox 
browser.
Restarts, new projects, old projects, now always my default browser is used. 

This solves my problem, but I have no idea what happened.
To me this is strange behavior, like the python line somehow changed a setting?

Greets,
Jeroen

This one opens Firefox...

So maybe it is an issue in qgis, I'll give it to Tom.

[Qgis-user] QGIS 3 Frozen

[Martin Bittens]

Hello Colleagues,

After I made the latest update I don´t get access to the plugin manager. 
Clicking on 'Plugins - Manage and Install Plugins...' QGIS stops to 
work. No error message appears, and to close QGIS I need to use the 
windows task manager. Currently, there are 3 QGIS versions on my computer:


QGIS 3.4.5

QGIS 3.6.0

QGIS 3.7.0

The result is always the same. QGIS is frozen.

I am working with Windows 10.

Does anybody know what is the reason for that error?

Thank your for your help.



Martin

[Qgis-user] Creating PNG images using QGIS 3 pygis

[wambacher]

Some days ago I upgraded from QGIS 2.18 to 3.6.0 - not knowing that many
Python scripts won't run without modifications.

I could convert all of them but not this one:

image.save(imageFile) |

Yes, I do know the QqsComposer has gone but I can't find any
documentation or example for QGIS3 plotting. Except the API description
of course.

I don't need the whole script converted - *only a hint how to create a
png the new way.*

Hi,
See

which depends on your operating system (see

[Qgis-user] Error Message When Packaging Application for Win7

[Carter, Cat]

Good afternoon all

My apologies but I am unsure which mailing list is the appropriate one to use.

Our support team are trying to package QGIS 3.4.4 'Madeira' for Win7 and Win10 
for deployment, however they are facing an issue with the Win7 extraction.

Extraction issues faced on win7:
1.extract:error writing to file gdal203.dll
2. extract:error writing to file vcredist-2013-x64.exe

[cid:image003.png@01D4CE75.4D1E3DB0]

Would anyone be able to provide any advice on what might be causing this error?

[Qgis-user] Function-editor: Where are custom functions stored

[Kai Behncke]

Dear users, 
I use Quantum GIS 3.6 on Windows.

if I create an own custom-function via the function editor, where is
this function stored (in which file?) ?

Thank you very much, Kai

Ciao Martina,
secondo me con un po' di ingegno si potrebbe fare

prova a usare la funzione transform(geom, source_auth_id, dest_auth_id)
applicata ad una delle due geometrie, cosi facendo, forse (non ho testato),
riesci ad usare aggregate anche con SR differenti.

facci sapere

saluti

[Qgis-user] QGIS-Kerning-Errors?

[Elstermann, Mike]

Hello, everybody,

When I use mass text with different markups (font attributes) over HTML text, 
kerning errors occur especially with small but necessary font sizes, i.e. the 
spacing becomes incorrect. The screenshot [1] should illustrate this. It is 
simple HTML (on the right). The errors occur equally in QGIS 2.14 and 3.2. Does 
anyone have an idea or a workaround?  What other possibilities are there for 
mass text with different attributes?

Here is the test HTML:

Re: [Qgis-user] QGIS package broken on Ubuntu Bionic with UbuntuGIS PPA

[Bernd Vogelgesang]

Hi César,

this is the lesson I had to learn hard a dozend of times over the years: 
Do not update any ububuntugis related packages "after" a QGIS version 
update.


Those two parts of the eco-system never managed to get in sync, and 
maybe never will (no idea how and why and what, I'm just a user).


On Linux Mint, I recently discovered in the Update manager the 
possibility to right-click on a package name, and set it to be ignored 
for updates.


And fortunately, a hover-over the package name reveals the source, so I 
can deactivate all ubuntugis packages for updates within seconds.


Hope this helps ... next time

Cheers,

Bernd

Hello,

I don't know if this is the right place to ask this, so apologies if

Today I updated my system through apt and the gdal package got 
upgraded to 2.4.0 and at the same time the qgis package got removed.


I'm using the ubuntugis-unstable PPA and the QGIS repo for ubuntugis:

deb http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu 
bionic main # ubuntugis

deb https://qgis.org/ubuntugis bionic main # QGIS

When I try to install QGIS again, apt complains of unmet dependencies:

# apt install qgis

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

      Recommends: qgis-plugin-grass but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I read online that removing ubuntugis and installig from the ubuntu 
repo would solve the problem but I'm relying on some ubuntugis package 
versions, so what's the recommended solution? Shouldn't QGIS 3.6 be 
able to run with GDAL 2.4.0?


Thanks in advance

Looking at the repos, I see new version of packages went up 10 hours
ago. It is possible the QGIS release on qgis.org ubuntugis repo needs to
be rebuilt against these new packages, which usually happens within 24
hours.

The qgis.org packages in the non-nightly repo are built on release and packages
and are not automatically rebuilt when dependencies changed - see the
note on

https://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu

that also lists a couple of options to deal with this.

Another option is to disable the ubuntugis ppa immidiately after a QGIS 
point release until QGIS calls for newer versions from it.


Unfortunately, you can't go back to GDAL 2.3 once it is updated on 
ubuntugis unstable. Same goes for GRASS.

Re: [Qgis-user] change default webbrowser in qgis3 settings?

[Groene Bij]

Short update on this issue.

After entering QDesktopServices.openUrl(QUrl('http://qgis.org')) and seeing 
qgis3 opening the firefox browser, now qgis2web also always opens the firefox 
browser.
Restarts, new projects, old projects, now always my default browser is used. 

This solves my problem, but I have no idea what happened.
To me this is strange behavior, like the python line somehow changed a setting?

Greets,
Jeroen

This one opens Firefox...

So maybe it is an issue in qgis, I'll give it to Tom.

Re: [Qgis-user] QGIS-Server and Out-Of-Memory

[Andrea Peri]

I guess my qgis-server is already 64bit ,
but i compile it from source and perhaps i wrongly guess is a 64bit. So i
will verify this.
Thx for hint.

I remember that when we had qgis server 32 bit, we could incur in out of
memory error quite often.
When we passed to 64 bit, those vanished!

Re: [QGIS-it-user] Funzione "aggregate" con variabile @parent su layer con SR diversi

[Martina Savarese]

Grazie,
avevo un caso in cui dovevo verificare la corretta ubicazione di un layer
punti (con un dato SR e con un campo striga contenente il nome del comune),
rispetto a un layer poligonale di comuni con altro SR e stesso campo. Allo
scopo di tale verifica ho pensato di poter utilizzare o l'algoritmo "Unisci
attributi per posizione" o uno spatial join con "aggregate", preferendo
quest'ultimo per avere un campo virtuale, con i valori concatenati da
virgola, e che successivamente potessi anche riutilizzare per altro
semplicemente sostituendo il campo nell'espressione (invece di avere una
serie di nomi di comuni separati da virgola, avere i nomi delle entità, la
tipologia o altro).
Alla fine ho risolto con "Unisci attributi per posizione" (senza dover
riproiettare uno dei due layer, dal momento che stavo lavorando con la 3),
ma mi è andata bene perché i punti con ubicazione sbagliata erano pochi: se
fossero stati molti di più avrei dovuto salvare il file di output per poter
proseguire a spostare i punti anche nei giorni successivi e magari
aggiungerci anche un campo di verifica da spuntare o segnarmi a che punto
ero arrivata con le correzioni, perché non avrei avuto il vantaggio di un
campo virtuale che si modifica man mano che correggevo i punti.
Tutta questa menata per dire che sarebbe stato utile se "aggregate" con
@parent funzionasse anche con layer di SR differenti e con il prossimo file
puntuale che dovrò correggere credo tutto sommato mi convenga riproiettare
il layer dei comuni :)
