[Qgis-user] OpenID autherntication in QGIS

[Newcomb, Doug via QGIS-User]

Trying to connect to ArcGIS Portal behind an OpenID frontend . Suggestions 
anyone?  I have read through the detailed directions at 
https://north-road.com/2022/09/16/securely-accessing-arcgis-online-agol-and-enterprise-arcgis-portal-sites-through-qgis-2022-update/
  , but that does not quite seem to fit this situation.

since several weeks I can´t open existing .qgz files from inside an open QGIS instance 
when they are located on a network drive. The error message that appears is "Unable 
to unzip file: ..."


Hi Simon,
you wrote that the issue occurs "since several weeks": did you use the 
very same QGIS 3.34.7 version even before several weeks ago when the 
issue didn't occur?


Have the Operative System been updated?

Which installer did you use to install QGIS, the OSGeo4W network 
installer osgeo4w-setup.exe or the OSGeo4W stand-alone all-in-one 
installer QGIS-OSGeo4W-3.34.7-2.msi or another one?


Have you tried if the issue occurs also using a new QGIS user profile?

Please read the previous thread in this mailing list about a similar 
issue 
https://www.mail-archive.com/qgis-user@lists.osgeo.org/msg53698.html and 
the previous issue report about a similar issue  on GitHub 
https://github.com/qgis/QGIS/issues/57535


Regards.

Re: [Qgis-user] problem when opening projects in open, instance

[Garth Fletcher via QGIS-User]

To further clarify:
I transferred both .qgz files from a USB disk to the user's Documents 
directory.

One opened, the other gav the "Unable to unzip file..." error.
So not a network or shared volume issue.

I did not know enough about Windows to try unzipping the .qgz file :-(

Back on the Mac system, both .gqz files on the USB disk opened normally.

So, it seems to me that the possibilities are:
 1) copying error in transferring from USB disk to User's home volume - 
unlikely

 2) .ZIP format issue between Mac OSX and Windows

I'll report further after I can test .qgs format on the Windows system.

[Simon Dietmann via QGIS-User]

Hi Richard,

tanks for your advice.

it´s possible to open the same .qgz normally when it is copied to local drive, 
and its also no problem to open the .qgz (renamed to .zip) ON the network drive 
and to open the .qgs inside. 

I´m sure that this is not an issue about synchronous writing access, because it 
happens very often with projects that are only used by me.

Seems to be a little mysterious ...

Regards,

Simon

I think it is important to know if it is an issue with the actual file (maybe 
corrupt etc, or maybe locked or so), or the combi of the file + on a network 
drive.

If you copy that same qgz file to your local disk, is QGIS then able to open it 
normally?
(if so: then it is network and possibly QGIS related)

Can you try 'unzip/unpack' the file with another 'unzip' program, when it is ON 
the network drive?
(if so it is QGIS/network related)

Note that a qgz file is a 'normal' zip. Just rename it to .zip to look into it. 
You will find the old .qgs file. Which actually is an xml file which you can 
see in an editor.

One of the issues with 'network drives' could be that several people on the 
same time are writing to it? Not sure if it can get corrupt in this way 
that is why I propose to look into it, IF you can open it as a zip.

1) Use 'zip -t' on the mac and again (however you spell that) on windows.

2) use some sort of cryptographic checksum (sha1, or md5 is good enough)
on the file on both systems.   It is possible that the file is getting
munged in transfer, especially if a windows system or SMB is involved ;-)

Dear Michael, its nothing personal,  about the "Philosophy of pacifism in times 
of war"

In concern for "Search and Rescue" purpose, it is allowed to answer you.
Not to answer your question in relation to the use of military technology may 
supports any peace foundation?
A company for military development is a "hot iron".
Whats your final purpose to use the map for?
Whats the Source of the origin map, a TIF -Picture, a WMS, or Verktor Data?

Re: [Qgis-user] Raster Tools

[Simon Dietmann via QGIS-User]

Hello Michael,

I think the problem here are the 2 map units per pixel, because in your CRS 
this means 2 degrees, so one pixel is about 200 km wide. You can try 0,001 for 
about 1 m.

Hope that helps, cheers

[Qgis-user] problem when opening projects in open instance

[Simon Dietmann via QGIS-User]

Dear list,

since several weeks I can´t open existing .qgz files from inside an open QGIS 
instance when they are located on a network drive. The error message that 
appears is "Unable to unzip file: ..."
There´s no problem when the .qgz is on a local drive or when I open it from the 
windows explorer.

I´m using latest QGIS Desktop 3.34.7 on  Windows 11.

Does anyone know about this problem? Any idea for a solution of this issue will 
be appreciated. In case you think it is a bug, I will post a report.

Thank you,

Simon

Re: [Qgis-user] Rendering shared exterior boundaries of adjacent polygon features

[Simon Dietmann via QGIS-User]

Hi Tim,

If I understood correctly what you want to do, I would suggest the following:


  1.  duplicate the layer
  2.  in the underlying layer, define rendering for area and the interior 
borders.
  3.  in the layer above, choose “merged features” and define the outer border 
lines as  e.g. “Outline: Simple line”

Is that what you intended to achieve?

Cheers,

Simon

Hi Tim,

Are you looking for the "Draw line only inside polygon" feature described at 
http://nyalldawson.net/2014/01/qgis-two-neat-features-in-2-2/
 ?

In that case you would probably have two symbol levels:

- one for the line pattern fill (cross-hatched)

- a second one on top of the other one drawing an "Outline:simple line" on top 
of it using the "Draw line only inside polygon" checkbox.

This is only briefly described at 
https://docs.qgis.org/3.34/en/docs/user_manual/style_library/symbol_selector.html

Quote:

Outline: simple line: uses a simple line symbol layer to represent the polygon 
boundary (Rings) which can be the interior rings only, the exterior ring only 
or all the rings). The Draw line only inside polygon option displays the 
polygon borders inside the polygon and can be useful to clearly represent 
adjacent polygon boundaries. The other settings for the outline simple line are 
the same as for simple line symbols.

But perhaps I am totally misunderstanding your request ...

Greetings,

Andreas

Fellow QGIS Users –



I’m trying to determine if its possible to have QGIS render the exterior 
boundary of polygon features only once when that boundary is shared with an 
adjacent feature (don’t render overlapping exterior boundaries for both polygon 
features).  The data I’m working with is a county parcels layer and the 
symbology I’m using for this layer is a cross hatched line fill with a separate 
component for the outline of the polygons.  I’ve tried a couple of expressions 
(examples below) including one geometry generator and one data defined override 
for the stroke width of the boundary line but none of them achieves my 
objective.  I’m using QGIS 3.34.7 and my coding skills are limited.  I feel 
like I’ve seen this issue covered somewhere but have been unable to find a 
solution after extensive online exploration.



Method #1: “boundary( difference( $geometry, aggregate( 'union', 'intersects', 
$geometry, other_layer := @layer)))”  This expression was used on the outline 
component of the symbology described above.



Method #2: “CASE WHEN intersects( $geometry, geom_to_wkt( boundary( $geometry 
))) THEN 0  ELSE 1 END”  Here I switched to using an expression on the stroke 
width of a simple fill, but I got an error message saying “Cannot convert to 
geometry”.



Any input would be greatly appreciated.



Tim
