In the ol-geocoder.js file that is created by qgis2web, search for:
"https://nominatim.openstreetmap.org/search/;


Hi Keith,
I've filed a Pull Request [1] to fix the issue in the qgis2web plugin.
I don't know if and when it will be merged and a new version of the 
plugin will be available (the plugin seems not constantly maintained).


Best regards.

Andrea

Ciao Salvatore,
probabilmente dipende da alcuni miglioramento apportati nella versione 3.32.
Vedi https://github.com/qgis/QGIS/issues/52796 e

A presto.

I've run into a similar problem (possibly the same) - that nothing shows 
because the layed is panned far away from screen center. Something to do 
with the Project not correctly storing the canvas center coords...


select one of your layers and then  View >> Zoom to Layer(s)

That will adjust Zoom and Pan to center and display the layer in the 
display...
Best to select one of your layers that only contains stuff from your 
Area of Interest
if you select some huge background layer then you will be zoomed far 
enough out to display the entire layer...

Perhaps there is a degree of misunderstanding here.

When you work with say Microsoft Word to eventually produce a document that
you will export to PDF to send to others, you don't save your interim work
in PDF; you save it in Word's internal format, .docx.

Similarly with QGIS, you save an ongoing piece of work as a project. Look
at the Project menu item, where you will see the ability to Save or Save
As.  When you're ready to export your work to PDF or some other output
format, there is an "export work flow".

There is also an important QGIS component not immediately visible, which is
the Print Layout, also available in the Project menu item.

You might wish to follow through the online documentation here
https://docs.qgis.org/3.28/en/docs/training_manual/map_composer/map_composer.html
to see how that component is used to make a map, with surround, annotation,
etc ready for export to PDF as a finished product.

So the overall workflow is to assemble the various layers you wish to
depict on the main QGIS screen, applying symbology to each layer; then open
a print layout to wrap up what's on screen into a full map composition.

Don't forget that you can add useful raster layers, like Open Street Map,
to your screen and map composition, to save yourself a lot of time with
respect to tracking down vector or raster data sets, symbolizing them, and
so forth.

In teoria la tua funzione é corretta ma probabilmente il modo di chiamare
la funzione, qgis ha bisogno che gli specifici gli altri argomenti anche se
non li usi. Credo sia dovuto al decoratore che hai messo sulla funzione.

2023-09-13 Thread Totò Fiandaca 
Ciao  TUTTI.
Scrivo per un comportamento strano che noto su QGIS 3.28.10 LTR Firenze da
OSGeo4W su win 10 PRO.

Con Giulio abbiamo creato una funzione personalizzata (per field calc) che
permette di estrarre il numero di pagine da un PDF.
la funzione è raggiungibile da questo link [1], è un gist.

Ho installato la relativa libreria usando OSGeo4W, la libreria è
pyton3-pypdf2 3.0.1-1
la libreria è installata bene perché da console python dentro QGIS
(qualsiasi versione) e lanciando lo script:

import PyPDF2
pdfFileObj = open("tuofile.pdf", 'rb')
pdfReader = PyPDF2.PdfReader(pdfFileObj)
print(len(pdfReader.pages))
pdfFileObj.close()

restituisce il numero delle pagine.

Il problema è il seguente:
1. QGIS 3.28.10 dà errore;
2. QGIS 3.28.10 con profilo pulito dà errore
3. QGIS 3.32.2 Lima FUNZIONA
4. su master FUNZIONA

L'errore è il seguente:

Errore Valutazione: Get_Pdf_N_Pages() takes 1 positional argument but 3
were given:

Traceback (most recent call last):

  File "C:\OSGeo4W/apps/qgis-ltr/./python\qgis\core\additions\qgsfunction.py",
line 81, in func

return self.function(*values)

TypeError: Get_Pdf_N_Pages() takes 1 positional argument but 3 were given


dentro il field calc scrivo:

Get_Pdf_N_Pages('C:\\Users\\x\\Desktop\\yy.pdf')

Chris, I could experiment with QGIS's cartography capabilities more if I could save my project, exit, and then resume working on it later. My other problem with QGIS interferes with that potential procedure.Yes, aligning a single layer in another app with its true position is a problem. If I continue trying to do it this way, I'd probably also output meridians and possibly other clues (e.g., the British coastline) to allow aligning it properly.Thanks for your perspective!Michael McNeilOn Sep 13, 2023, at 10:06, chris hermansen  wrote:Michael and list,On Wed, Sep 13, 2023 at 10:00 AM Michael Edward McNeil via QGIS-User  wrote:I'm an almost total novice with regard to GIS in general and QGIS in particular.

Is there any reason you can't do your cartography within QGIS?  Or at
least, make a "simplified" draft map, save as an image or PDF, and then do
whatever "graphical finishing" required in your desktop publishing
application?

I think this would be a more "normal" approach, rather than exporting a
layer by itself, if for no other reason than your geospatial information
will be properly aligned by QGIS in the final product.

[Qgis-user] Output to pdf file doesn't contain vector details

2023-09-13 Thread Michael Edward McNeil via QGIS-User 
I'm an almost total novice with regard to GIS in general and QGIS in 
particular. Nonetheless I've been attempting to put together a test map (using 
data I will make use of, in part) utilizing the contour lines for the island of 
Great Britain – obtaining data in that regard from the space shuttle's 
worldwide Shuttle Radar Topography Mission (SRTM).

I obtained the data and loaded it into QGIS, no problem. After extracting the 
contours, the lines shown in QGIS are nice and sharp, and vectorize properly 
when zooming in and out. I'm using 100 meters between lines (rather than the 
default 10 m) which means that in some regions of the planet, they're not all 
that dense; nonetheless if you're looking at a larger scale view of, say, Wales 
or Scotland, the contour lines show up at that scale as generally pretty dense. 
The solution, of course, using vector graphics is to zoom in, then you can see 
the full detail.

Anyway, things are fine while still within QGIS (except for the secondary issue 
noted below). However, I wanted to output the vectorized contour lines into a 
file I could input into (e.g.) CorelDRAW to add other layers and do the 
graphical finishing touches on the desired map. I tried svg format – got the 
message about svg handling in QGIS being buggy – and indeed the svg output 
didn't seem to work.

So, I tried pdf. What I get there (out of an 80 GB resulting pdf file!) is 
simply solid color – not distinguishable contour lines – in regions where the 
lines would otherwise (at a larger scale) be dense. I told the output Layout 
page that it should vectorize all output – but zooming in doesn't help. (I 
recall that my svg format experiment also similarly produced solid color and 
lacked contour detail.)

What am I doing wrong?

A secondary issue, by the way, is that I apparently can't see the data after I 
save my QGIS project, close and re-enter the app. After re-entering QGIS the 
Layers pane shows all the layers, all properly check-marked for visibility, 
just like before, but nothing shows up in the display window – it's totally 
blank white. So… I'm surviving by never (or seldom – then reloading the data) 
leaving the app. But, what's going on?

I'm running QGIS v. 3.32.2-Lima under MacOS 12.6.8.

Thanks, all.

Best,
Michael McNeil

Re: [Qgis-user] Error! No Internet connection? OSM Place Search plugin error

2023-09-13 Thread Keith Jenkins via QGIS-User 
Hi, Jared.

Yes, the problem seems to be when checking the "Add address search"
box under the "Appearance" tab in qgis2web and exporting to OpenLayers
(as noted by Andrea).

I checked the network traffic from an exported map, which is making a
request like:
https://nominatim.openstreetmap.org/search/?q=kinshasa=json=1=5==en-US

According to the response to that request, the Nominatim API has been
changed, making the request invalid.  However, it is an easy fix,
since a single slash just needs to be removed.

In the ol-geocoder.js file that is created by qgis2web, search for:
"https://nominatim.openstreetmap.org/search/;

and change it to
"https://nominatim.openstreetmap.org/search;

And then the search box should work.

Cheers,
Keith

Risolto il problema.
Mille grazie e scusa molto per il disturbo.
Era proprio una scemata e avrei dovuto porre più attenzione.
Pur avendo letto gli errori in Log
non avevo mai notato che nell'agoritmo di processo dopo la versione 
3.4.2 era stata aggiunta

l'opzione che mi hai scritto di selezionare.


Purtroppo i log di esecuzione sono spesso molto lunghi e un po' criptici 
e non è facile trovare l'errore che genera il problema...
Inoltre, nel manuale utente di QGIS non sono documentati gli algoritmi 
di processing di GRASS-GIS nè le varie opzioni avanzate, e quindi non è 
facile trovare informazioni su tale opzione.


A presto.

Re: [Qgis-user] Error! No Internet connection? OSM Place Search plugin error

2023-09-13 Thread Andrea Giudiceandrea via QGIS-User 

Hi Jared,
I can confirm what Frank wrote: the "OSM place search" QGIS plugin is 
available in the official QGIS Python plugins repository [1], anyway 
such plugin has very likely nothing to do with the web map error, which, 
if I understood correctly, doesn't occur using QGIS and the "OSM place 
search" plugin, but it occurs using the web map.


It seems to me the error message very likely comes from the "OpenLayers 
Control Geocoder" [2] which is an OpenLayers extension used by the web 
map [3].


Best regards.

Andrea
