Re: [Qgis-user] OpenLayersPlugin

[Bernd Vogelgesang]

I suppose you got this idea to use OpenLayers plugin from some web
rescources.
As QGIS advances very fast, it's crucial to have a look at the date when
it was created. Tuturials older than lets say 2 years are more or less
unusable already.
... and follow Paolos advice (he was faster to post)

Cheers

Hi Tim,
please upgrade to the latest LTR version, now 3.10.
Instead of OL plugin, you can use QuickWebServices.
All the best.

Re: [QGIS-it-user] QGIS 3.10 Windows e Mergin

[Luca Puglisi]

Ciao,

se non sbaglio, dopo aver caricato il progetto su Input bisogna fare il 
download dal pannello browser di QGis. Una procedura in vero un po' 
bizzarra, pero' poi aprendo quello scaricato poi la sincronizzazione tra 
QGis e Inut funzionava bene.

Spero di aver ricostruito bene i passaggi...

Buongiorno Luca

effettivamente dopo un po' di apri/chiudidi Qgis  è apparso il nuovo 
servizio sulla TOC di Qgis.


Allora ho creato il progetto con Geopackage e postato in Mergin

Poi ho scaricato Input sullo smart, visualizzato il il progetto

Ho aggiunto dei dati, salvato e sincronizzato.

Aperto Qgis ho risincronizzato il progetto ma non vedo i dati aggiornati


Hai fatto anche tu questo percorso ?


Grazie

Franco

[Qgis-user] Support for writing vector tiles in QGIS

[Saber Razmjooei]

Dear QGIS Users,

We have managed to secure our target for reading vector tiles in QGIS. We
had also several requests to support writing vector tiles directly from
within QGIS. Therefore, we have extended the scope and crowdfunding goal to
cover this feature:
https://www.lutraconsulting.co.uk/crowdfunding/vectortile-qgis/

Today is the final day of the campaign, so it is your last chance to
contribute if you'd like to see this feature in QGIS 3.14.

Many thanks
Saber

uno dei tanti posti in cui python si può lanciare ma sembra nascosto :)

> 1. la form la posso creare con Qt Designer o altri applicativi ?

Qt Designer è la scelta ottimale

che sappia io no. per ò quando sei nella scehda "Attributes Form", in
alto a destra (vicino al menù a tendina di "Atuogenerate") c'è il
pulsantino di python. Qui puoi usare codice da aggiungere al tuo modulo

Hi,

You need to use a Relation, in the project properties (Menu: Project >

See these videos to understand how it works :

im trying to import this spreadsheet to a map of parcells  and what happen

how can I show  2 functions or more related to the same parcel  ?

I can use the add polygon feature but than it should be done manually one

[Qgis-user] Always render as raster losing opacity control and simplify vector layers

[Michael Dufty]

I’ve had an interesting couple of days dealing with PDF sizes.  We have a very 
large vector layer of flood model output, being put into an A3 map covering a 
large area.
Initially this produced a 5MB ish PDF, but at some stage the PDF size jumped to 
30MB.  It looks like the new “simplify geometries to reduce output size” option 
was not working.
We were able to get around this by forcing the layer to render as a raster in 
the layer properties.
A couple of days later we decided the layer should have 100% opacity instead of 
80%.
The opacity displayed correctly in the main map and layout, but in the PDF 
exports it stayed stubbornly at 80%.
Turning off the force to render as raster allowed the opacity to display 
correctly again.  The file size stayed low too, so simplify geometries seems to 
work again.

At this stage we have solved the practical problem, but I’m still curious about 
the underlying issue.

Switching back to render as raster broke it again.
Re-adding the shapefile did not work.
Forcing another layer to render as raster resulted in both correct behaviour on 
the new layer, and fixing the problem on the old layer.
Turning off the forcing on the second layer, results in the first layer playing 
up again.

Initial issues were using 3.10.1 now on 3.12.

Anyone have a clue what might be going on?
Seems like there might be a cached version of the rasterization somewhere, but 
it recurs even if I change the colour.
I notice raster layers have opacity set in a different place to vector layers, 
so perhaps the opacity level for the generated raster layer has somehow been 
saved somewhere.
