 This is how things work. And if people have to do 100% of their searches
out of the docs, maybe should we stop (trying) to maintain it.

What you need to do is edit the type and status rules, and uncheck the
"symbol" checkbox in their properties. That will make them logic only
rules which don't render any of these unwanted group symbols.

[Qgis-user] Rule-based styling: Why are all levels shown?

[Bernd Vogelgesang]

Hi,

I seem to be a bit dumb.

I try to set up rule-based styling for point observations which I like
to break down for three columns.

"type": observation|catch
-- "status": unknown|juvenile|subadult|adult
"gender": "unknown|male|female

In my understanding of a rule based styling of e.g. type = observation,
status = adult and gender = male, the symbol for male within adult
within observation should be shown exclusively.

Instead all three symbols for the type, the status and the gender are
displayed over each other.

I really seem to misunderstand the concept of those nested styles, cause
actually the do not nest, but happily pile over each other.

Glad for any hint,

Bernd

Hi Tyler,

It's not a bug. A 3.0 feature that may not look obvious at first sight.
This button indicates the advanced configuration, hence those tools are
hidden since they are enabled on a layer basis. Press that icon and select
the "Open snapping Options..." at the bottom of the drop-down menu and you
get a dialog with the options available.
Pressing that icon also allows you to switch to the "all layers" or "active
layer" configurations which both show the tools you are missing.
Do not forget that snapping is a project property, reason why the configs
of this file is propagated to files that derived from it.

[Qgis-user] Interesting anomaly with the snapping toolbar

[Tyler Veinot]

Hi All;
I have one map document that when I open it my snapping toolbar changes
from this...
[image: image.png]
To this...
[image: image.png]

See how the settings for layer and snap to/tolerance disappeared?
It only seems to happen with one specific map document and any document
created from it as a base. I tried looking for a setting I might have in my
document that would change the snapping tool bar but couldn't find
anything. Has anyone else had this issue? Is it a something I can fix or is
it a corruption of the map document file.
Thanks;

Re: [Qgis-user] qlr of spatialite database layer not showing when database is on network drive

[Robert Nuske]

Hi Reginald,

SQLite has problems writing on Network File Systems/Samba Shares due to 
the poor support for locking. I remember one case where this was 
"handled" by writing to a local SQLite file and replace the SQLite file 
on the network drive with the local SQLite file after writing finished.



See for instance
https://trac.osgeo.org/gdal/wiki/UserDocs/SQLite
https://www.sqlite.org/faq.html#q5

Hi,

this process is outlined on the developer's web site:
https://www.kyngchaos.com/software/frameworks/

Look for the section titled "GDAL Plugins" and find the corresponding
plugin for your version of GDAL.

The Lat Lon Tools plugin does this conversion to put the coordinates into
one or two fields. See "Plugins->Lat Lon Tools->Conversions->Point layer to
fields". It has a lot of flexibility as to the output format.

[Qgis-user] Flatpak

[Raphael Das Gupta]

Heya all

I know that https://qgis.org/en/site/forusers/alldownloads.html#flatpak 
lists the flatpak for QGIS "Stable" (is that the same as LTR?) as 
"experimental", but does anyone at least read issues that are being 
filed? (No offense intended, just genuinely wondering whether this is 
still being maintained.)


I'd be particularly interested in the ones I've filed myself:

https://github.com/flathub/org.qgis.qgis/issues/24 make QGIS 3.4.5 
(latest LTR) available
https://github.com/flathub/org.qgis.qgis/issues/25 Can QGIS 3.6.0 
(latest non-LTR) be installed through flatpack?


I'd like to help with updating the flatpack to QGIS 3.4.5, but can't 
even get its current version (3.4.4) nor the flatpak repo's master 
branch (QGIS 3.6.0) to build locally, yet. 
(https://github.com/flathub/org.qgis.qgis/issues/26 ; though maybe 
that's due to my kinda exotic operating system. But I guess issues with 
the build process are more a topic for qgis-develo...@lists.osgeo.org 
than for qgis-user, anyway?)


Cheers,
Raphael

Carissimi,
sto riscontrando diversi problemi ad installare QGIS Server 3.4 su un

Ho aggiunto i seguenti repository a /etc/apt/sources.list

deb http://qgis.org/ubuntugis-ltr xenial main

Con questi aggiunti, col comando apt-cache policy qgis-server mi 
individua correttamente la versione 3.4.5+24xenial-ubuntugis

ma quando gli dico di installare mi lascia questi errori

# apt-get -y install qgis-server python-qgis

Ho provato ad installare manualmente ma non le trova, gli stessi 
errori li ho anche se provo ad installare qgis.

Qualcuno ha sperimentato gli stessi errori?


Provando a installare le dipendenze si arriva a questo:

$ apt-get install libqgis-core3.4.5
.

The following packages have unmet dependencies:
 libqgis-core3.4.5 : Depends: libgdal20 (>= 2.2.0) but it is not

E: Unable to correct problems, you have held broken packages.

Che vuol dire non esserci una libgidal30 >= 2.2.0 per Ubuntu Trusty né 
in quel repository, né nei repo standard di Ubuntu.


Dove trovarla non lo so ma il motivo primigenio è questo.

Saluti, Matteo.



Ho fatto la stessa installazione anche su un server ubuntu 18 bionic 
ed è filata liscissima, purtoppo non posso fare l'upgrade di ubuntu 16.


Grazie mille

Re: [QGIS-it-user] Servizio WMS del SIT Regione Lazio su QGIS. Considerazioni varie

[Marco Spaziani]

Sei stato chiarissimo. Grazie da parte mia e da parte di tutti gli
utilizzatori del sistema WMS dell'OpenData della Regione Lazio.

Hi, try 3.6 - you might find it works fine.  It was very buggy in previous
versions, including 3.4, although I'm not sure if it is fixed in the latest
version of 3.4

[QGIS-it-user] Installazione QGIS Server su Ubuntu 16 xenial

[Federico Gianoli]

Carissimi,
sto riscontrando diversi problemi ad installare QGIS Server 3.4 su un
server con ubuntu 16 xenial.

Ho aggiunto i seguenti repository a /etc/apt/sources.list

deb http://qgis.org/ubuntugis-ltr xenial main
deb-src http://qgis.org/ubuntugis-ltr xenial main

Con questi aggiunti, col comando apt-cache policy qgis-server mi individua
correttamente la versione 3.4.5+24xenial-ubuntugis
ma quando gli dico di installare mi lascia questi errori

# apt-get -y install qgis-server python-qgis

Reading package lists... Done

   Depends: libqgis-server3.4.5 but it is not going to be
installed
E: Unable to correct problems, you have held broken packages.


Ho provato ad installare manualmente ma non le trova, gli stessi errori li
ho anche se provo ad installare qgis.
Qualcuno ha sperimentato gli stessi errori?

Ho fatto la stessa installazione anche su un server ubuntu 18 bionic ed è
filata liscissima, purtoppo non posso fare l'upgrade di ubuntu 16.

Grazie mille

Federico

Ciao Marco,
il link del WMS che ti hanno dato è
http://geoportale.regione.lazio.it/geoserver_nsit/dbgt/wms

però nelle capabilities restituite dal server a quel link
(http://geoportale.regione.lazio.it/geoserver_nsit/dbgt/wms?service=wms=GetCapabilities)
viene riportato un URL leggermente diverso per la richiesta effettiva delle
immagini (richiesta GetMap):

http://geoportale.regione.lazio.it:80/geoserver_nsit/dbgt/ows

QGIS normalmente ottempera a quanto prescritto nelle capabilities, ma usando
quest'ultimo URL per la richiesta (GetMap) delle immagini della CTR, il WMS
non invia l'immagine ma restituisce l'errore "403 Forbidden" "You don't have
permission to access /geoserver_nsit/dbgt/ows on this server.".

Penso che il WMS non sia configurato correttamente o che comunque ci sia un
conflitto tra l'implementazione delle specifiche in QGIS e del WMS.

L'opzione "Ignora la URI GetMap/GetTitle riportata nelle capabilities" (così
come "Ignora la URI GetFeatureInfo riportata nelle capabilities" per le
richieste GetFeatureInfo) serve proprio a risolvere questo tipo di problemi
(che evidentemente non è infrequente).

L'errore che continui a vedere è relativo alla legenda del layer WMS il cui
URL riportato nelle capabilities è quello "sbagliato", ma mi pare non ci sia
un'analoga opzione che possa essere utilizzata per ovviare a questo
problema.

A presto.

Andrea

is the result not visible or does it have "strange" values? If so, try
to go in the layer style panel and change the min and max values

[Qgis-user] how to fix the raster calculator

[shalum HOUENOU]

Hi all,
I'm using a QJIS 3.4 under window 10.
I have issue with the raster calculator tool located in raster analysis
section of the processing tool.
After calculations the output layers are not visible no matter the data i'm
using.
I've already uninstall and reinstall the software and it is still doing the
same thing.
How could I fix it?
Thanks for your advices

Re: [Qgis-user] Coordinates from wgs84 utm /expressed in meter) to wgs84 (expressed in degrees)

[Bernd Vogelgesang]

Hi Nyall,

as much as I like your initiative to add such a function, I think such
examples should also be listed in the user manual connected to the field
calculator section.

Unfortunately, in this very important field, qgis resources do not give
many hints how to use the powers of the existing functions. Me, I do
100% of my searches on gis.stackexchange.com to find solution, not the docs.

Cheers,
Bernd

I think this is a common enough task to warrant it's own processing

(so will be in 3.8), ported from some Python code I used at a

Funziona (anche se continua a comparire il messaggio d'errore, vedi Fig_1).
Ci riusciresti, in due parole due, supertelegrafico, a spiegarmi perchè il
tuo suggerimento ha sbloccato il problema?
Grazie
P.S. ...pensierino ad alta voce ...meno male che c'è questa lista che, come
Mr. Wolf in Pulp Fiction, "risolve problemi", altrimenti, se dovessimo stare
nelle grazie degli Entie che dovrebbero rendere pubbliche nonché facilmente
accessibili e fruibili le loro cartografie, ...si arriva a "quota 100" senza
riuscire a cavare un ragno dal buco.
