No, the last number (.4 in your case), is the number of bugfix versions. No
new features are added in these bugfix versions.
The stable release on 3.22 is 3.22.16
https://www.qgis.org/en/site/getinvolved/development/roadmap.html#release-schedule
And 3.22 and 3.28 are already not maintained.

Hi,

You have installed the plugin "Value tool", you can remove it.
You should report this issue to the plugin author, there is a bug tracker :
https://github.com/jorgealmerio/valuetool

You are using QGIS 3.22.4, you should try to upgrade as well, it's old.

Re: [Qgis-user] Qgis server : problem with qgis server logs

[Etienne Trimaille via QGIS-User]

Hi,

It's still possible to use QGIS_SERVER_LOG_FILE, but it's deprecated, you
can see it in the documentation
https://docs.qgis.org/3.28/en/docs/server_manual/config.html#environment-variables
QGIS_SERVER_LOG_STDERR will send logs to stderr.

In the ticket, it was using Nginx.
But anyway, you don't need that anymore, indeed the "qgis_mapserv.fcgi

Re: [Qgis-user] Change properties of multiple layer at once

[Etienne Trimaille via Qgis-user]

You could use the LayerBoard plugin for that. It's available in the plugin
manager. Possible to change different kinds of properties at once for many
layers.
But AFAIK, this plugin needs some help ;-)

Re: [Qgis-user] How to make diagonals

[Etienne Trimaille]

Maybe "oriented_bbox" to get first a proper rectangle ?
https://docs.qgis.org/testing/en/docs/user_manual/expressions/functions_list.html#oriented-bbox

But then, you might have some tiny leftover. It depends if you care or not.

Otherwise, you need to use the angle at each points.

I thought there is the longest line possible within a polygon, but I can't
find it. I did it manually a few years ago.

Re: [Qgis-user] QGIS: Export Metadata from postgis tables to shp?

[Etienne Trimaille]

Hi,

>From the PgMetadata plugin, you can export a single metadata sheet to PDF,
HTML or DCAT. You can also export your full catalog (the last button in the
dock, then you can "save as" your new layer).
It's possible to improve the PgMetadata plugin by saving the layer metadata
when the user is clicking "save as" on a layer which is stored in
postgresql.
PgMetadata is a "small" PG schema, so it's easy to extract information we
need.

How to retrieve data from PgMetadata in another application :
https://docs.3liz.org/qgis-pgmetadata-plugin/user-guide/advanced/

The database schema :

A plugin is very often the culprit, which is installed by the user :)
(plugin or custom python expressions, custom Python script, processing
script)
When I have some crashes, I just disable new plugins that I have recently
downloaded and check. It's sometimes enough.
So enable your previous plugins step by step.
Plugin source code is stored in the profile itself, but the profile is not
really "corrupted". There are just some Python code inside. By removing it,
it's alright.

Re: [Qgis-user] loadNamedStyle

[Etienne Trimaille]

Quick answer,

You might want to have a look to
https://qgis.org/api/classQgsProcessingUtils.html#aa1c2360e52d2ed8100faf02a35125b17
I'm not sure about writing a processing script with this syntax, I'm still
using the class way. But you might want to set your style in a post
processor QgsProcessingLayerPostProcessorInterface?

Or why not using the builtin processing script to load a style ? Just
pre-fill values and call this algorithm ?

Re: [Qgis-user] PyGQIS output a layer? v3.16

[Etienne Trimaille]

A QgsProcessingOutputVectorLayer will understand you are returning a
QgsVectorLayer.

Maybe I'm wrong, but it works well :

Re: [Qgis-user] [QGIS-Developer] processAlgorithm vs processFeature?

[Etienne Trimaille]

Indeed, if you can, you should use a QgsProcessingFeatureBasedAlgorithm
algorithm. It will make some shortcuts for you and the code is shorter
because you will only have a single feature to process.

Have a look to existing source code :
https://github.com/qgis/QGIS/search?q=QgsProcessingFeatureBasedAlgorithm

Re: [Qgis-user] PyGQIS output a layer? v3.16

[Etienne Trimaille]

You can output a QgsVectorLayer :
https://qgis.org/api/classQgsProcessingOutputVectorLayer.html
The sink is not required and you would avoid a loop to insert all features.

I think you should also return sink ID or layer ID, not the object itself.

You should first upgrade your version, 3.10.2 is very old and 3.10.X is not
maintained anymore. Maybe this bug has already been fixed ?

Sorry, I'm just joining late.

Lizmap is a opensource solution that you can install on your own server.
So you need to care about hosting, upgrades etc.
The source code is on GitHub : https://github.com/3liz/lizmap-web-client/

Same for QGIS Cloud which is running QGIS Web Client, also available on
Github.
https://github.com/qgis/qwc2

Same for G3W-Suite : https://github.com/g3w-suite

But indeed, each of these products have also a paid hosting plan provided
by a private company if you don't want to care about hosting.

Can you try that?

Nonedef postProcessLayer(self, layer, context, feedback):
layer.setName('DiffLayer')@staticmethoddef create() ->
'Renamer':Renamer.instance = Renamer()return
Renamer.instance


In your processAlgorithm method() :


context.layerToLoadOnCompletionDetails(
data[layer].id()).setPostProcessor(
Renamer.create())

Re: [Qgis-user] A few hours in the Training Manual

[Etienne Trimaille]

Thanks for your feedback.
The documentation team is doing their best to maintain this manual up to
date. But it's not easy.

You should create separate ticket in the github repository :
https://github.com/qgis/QGIS-Documentation
It will not be lost like emails.

Feel free to edit manually on github if you find some typo for instance.

For the "routes.shp", if you need to create a new layer (not adding an
existing file), you are indeed correct, but ALWAYS use the "..." button,
because it's a filepath, not filename. It will solve your problem.
Choose a directory where you have write permission.

Re: [Qgis-user] Deploy maps/data to clients - web map solutions or other?

[Etienne Trimaille]

There are a few web GIS clients for QGIS.
Some are designed to be "static" like :
- QGIS2Web
- Mappia Publisher
- ...
They generate a HTML output.

And some are a complete web gis client with a server app to install
(usually with QGIS-Server):
- Lizmap: https://demo.lizmap.com/lizmap/
- GisQuick http://gisquick.org/
- QGIS Web Client https://github.com/qgis/QGIS-Web-Client

Indeed, there is auto completion when you type, but you can also type
whatever you want, nothing is forced using these text areas.

And if needed, you can click the "Show query" button and update it to fit
your needs (to change some values for instance).

Re: [Qgis-user] QGIS Server and webmapping information

[Etienne Trimaille]

Hi,

qgis2web will generate a static website that you can easily move on a
server somewhere, without the need to install QGIS Server.
The website will be generated from the plugin itself.

If you install QGIS Server only, you will have only some OGC streams such
as WMS, WFS etc. It's just to publish "data" on the internet. But you won't
have the web viewer in an internet browser.
Then you need to code the web application using Leaflet or OpenLayers.

If you use QGIS Web Client, Lizmap or similar, the web application is
already there and will offer some widgets and some tools. It will try to
mimic the QGIS Desktop application with the layer tree, the print layouts,
dataviz etc.

I tried to make this schema :
https://docs.lizmap.com/next/en/introduction.html I hope it can help you.

There are a few QGIS web applications : QGIS Web Client, Lizmap, GisQuick,
Mappia

Re: [Qgis-user] PyQGIS in Jupyter

[Etienne Trimaille]

Can you raise your question on the Github issue tracker? Thanks
It seems it's indeed generating the image from the QgsVectorLayer and then
asking matplotlib to display the image :(
As I said, it was a kind of proof of concept, my colleague did that part, I
hope he will answer you on github.

Re: [Qgis-user] PyQGIS in Jupyter

[Etienne Trimaille]

Hi,

One of my colleague in my company started a quick proof of concept using
Jupyter with QGIS.
I haven't tried it yet. It's available on github:
https://github.com/3liz/qgis-nbextension

I think it might be good for a PyQGIS training.

Feel free to provide feedbacks.

Re: [Qgis-user] QGIS Server / GetPrint not rendering all the layers (XYZ Tiles for example)

[Etienne Trimaille]

Hi Arnaud,

It looks like a cache write issue.

QGIS_OPTIONS_PATH must be a directory, not a file path.
https://docs.qgis.org/testing/en/docs/user_manual/working_with_ogc/server/config.html#qgis-options-path

I would add QGIS_OPTIONS_PATH too. And check that the profile is writable
for QGIS Server (www-data?). After the GetPrint request, I think you should
see the cache folder created.

This my config :

QGIS_CUSTOM_CONFIG_PATH=/home/etienne/dev/qgis/server_home/profile
QGIS_OPTIONS_PATH=/home/etienne/dev/qgis/server_home
QGIS_PLUGINPATH=/home/etienne/dev/qgis/server_plugin

Can you check that?

Re: [Qgis-user] Table manager

[Etienne Trimaille]

Indeed Table Manager was already deprecated for some functions in QGIS 2
IIRC.

But it depends what you wanted to do with TableManager. If you simply
wanted to rename fields, you can go in the vector layer properties,
"fields" tab and rename columns there. No need to use the "refactor fields"
algorithms, which will regenerate a new layer.

It depends how you store geometries inside the CSV I guess. Geometries as

Re: [Qgis-user] How to get a point's coordinate for GPS?

[Etienne Trimaille]

I will just add 2 tips to Raymond's answer.

* In the field calculator, you can create a "virtual" field, so the content
is updated everytime you move a point, or you create a new one.
* With these expressions, you will get decimal values. Since QGIS 3.4, you
can have DMS or DM values (convenient for GPS)
to_dms(x(transform( $geometry, 'EPSG:2444', 'EPSG:4326'))),'x', 3)

Re: [Qgis-user] writing vector data for QGIS input from a python script using osgeo ogr

[Etienne Trimaille]

QGIS is using OGR in the background to read vector data. So every format
supported by OGR is fine for QGIS. You can write geojson, geopackage,
sqlite, shapefile, it's fine for OGR API(write) and QGIS Desktop (read).
But are you sure you want to use the OGR API to write your file? IMHO, QGIS
API is easier.

As a temporary workaround, after you executed your query, go in your
temporary folder (/tmp on linux) and open manually the latest OSM file
provided.

Hi Matteo,

I noticed the issue too.

With QGIS 3.2, no problem, QuickOSM is working well.
With QGIS 3.3, not working since 1 week. But QuickOSM is not failling in
its processing, no python error. The plugin raises a warning if no OSM
object are found, but this is not the case, no warnings. So it means that
the plugin could download and parse some features. But at the end of the
process, layers are empty. The same plugin version is working on 3.2 and on
master a few weeks ago.

Re: [Qgis-user] Plugin ArrayPlus in conflit with QGIS 3.3

[Etienne Trimaille]

Hi,

I think you shouldn't mark it as deprecated until all functions are in QGIS
core.
Indeed, https://github.com/qgis/QGIS/pull/7645 won't be merged until 3.6,
the feature freeze is ON since friday for 3.4.

If I were you, I would still release the plugin with 3.0 minimum verison
and add something like "if Qgis.QGIS_VERSION_INT
 <
30300: register foo()" according to the current QGIS version.

About array_lambda, there is now array_foreach in QGIS core using an
expression.

Values are written in the link I put about -1, 1, yes. Often, with OSM
data, you need some pre-processing to clean all these values. It's based on
the direction of the line.

Maybe shapefiles from geofabrik are cleaner?

Sorry, I fail to understand. With OSM data in QGIS, you have the 'oneway'
column in the attribute table. If the field is empty, it means either OSM
doesn't have data for that road or by default it's not oneway.

https://wiki.openstreetmap.org/wiki/Key:oneway oneway=no is the default so
OSM contributors let this field empty. (only to avoid a confusion in some
areas).

http://www.kyngchaos.com/software/qgis
QGIS 2 is maintained until January 2019, can you put back at least the QGIS
2.18.15 so users can download it again? Thanks.

Re: [Qgis-user] Where is georeferencer plugin in QGIS 3 ?

[Etienne Trimaille]

Bonjour,

As you said, the georeferencer is a plugin. You should find it in your
plugin manager and activate it.

Etienne

Re: [Qgis-user] QGIS 3 : Python scripts

[Etienne Trimaille]

We should say somewhere that it's not a "script" with some simple commands
anymore (such as print()), but it's now following OOP (Object Oriented
Programming) and the user must define his class and methods following the
QGIS algorithm.

Can we provide a template in the editor? Is-there a working script
somewhere?

Thanks for pointing this. I'm aware of it.

Re: [Qgis-user] Error message: Processing toolbox

[Etienne Trimaille]

2.18.X doesn't bring new features, only bug fixes, so it's better to update
your QGIS 2.18. It won't break your projects. Your bug has been fixed a few
months ago. It was not related to your script.

Hi,

You should avoid cross-posting on many mailing lists. (qgis-user and
qgis-dev)

You should update your version of QGIS 2.18, this bug has already been
fixed. You won't lose your projects.

Re: [Qgis-user] Anybody knows how to download OSM Turn Restrictions?

[Etienne Trimaille]

Using QuickOSM, there are 2 specials Processing algorithms to deal with OSM
Relations which are not multipolygons, routes or boundaries. It's using XML
Sax parser because OGR can't read these relations. I agree, it's missing
some docs here.

Re: [Qgis-user] QGIS resource sharing plugin crashes QGIS

[Etienne Trimaille]

It's a known issue with every plugins using QWebKit with Ubuntu qgis 2.16.
It seems that the latest QGIS Nightly build fixed this bug :

Re: [Qgis-user] "live" openstreetmap data in qgis

[Etienne Trimaille]

Thanks Kimaidou. QuickOSM is also a nice idea, especially for a small area
like 1MB !
You can draw your model in QGIS Processing, look at the end of the video :
https://vimeo.com/108737868
I agree is not very convenient to have all these boxes in QuickOSM, one
called "quickquery" would be very appreciated.

Then as Michael said, you can do a macro or just add a custom button to
your model (in the latest processing version)

Don't hesitate to raise an issue or a PR to QuickOSM. A new version of
QuickOSM will be released if needed when you want.
BTW, Paolo, is it possible to get QuickOSM trusted ?

Regards,
Etienne

Re: [Qgis-user] "live" openstreetmap data in qgis

[Etienne Trimaille]

You have to set up a database with the OSM diff to get an up to date OSM
database. Then you can add your PostGIS layers in QGIS.

You can have a look to this docker project :
https://github.com/kartoza/docker-osm
These OSM layers are updated every two minutes by default, and you can see
these layers in QGIS.

I don't know why QGIS says "Download has been successful", but obviously
337 bytes is not enough.
Your bounding box is far too big to download for a request on the fly. You
should download your data using external services like
http://download.geofabrik.de/north-america.html

This tool in QGIS can download a neighborhood or a small town.

Re: [Qgis-user] Export plugins list

[Etienne Trimaille]

I agree, but it's the only solution for now to do that.
The plugin manager will update them after.

Or you can write a tiny script for that : ls ~/.qgis2/python/plugins/ >
list_plugins.txt to save the list.
And then a bash loop with wget to fetch the zip.

Re: [Qgis-user] OSM download error

[Etienne Trimaille]

You can use the QuickOSM plugin. It deals with the overpass API. You can
specify which feature you want.
QuickOSM can also open an external OSM file if you want to get all the
columns available. From the menu Add vector layer, it's not possible.

If you don't mind about columns and specific feature, have a look to the
OSM downloader plugin.

[Qgis-user] QuickOSM, a QGIS plugin to query Overpass

[Etienne Trimaille]

Hi,

For those who do not already know, a QGIS plugin exists so as to run an
overpass query.

This plugin is QuickOSM which you can find in the QGIS's repository :
- using keys/values with autocompletion
- use an extent of the map canvas or an nominatim area
- use some actions so as to edit in JOSM or open external links like
wikipedia
- save your query
- change the default geographic extent of a saved query
- apply some symbology if possible
- use QuickOSM in complexe models of QGIS Processing : fetching some datas
then reprojecte them for instance
-open a osm file by specifying the OGR file 'osmconf'

There is a little video : https://vimeo.com/108737868

I've developped this project during my internship at 3Liz :

Re: [Qgis-user] Retrieve in python api the list of layers in a project

2014-06-25 16:44 GMT+02:00 Andrea Peri aperi2...@gmail.com:

 Hi,

 In API python there a method to retrieve the list of all the layers in
 the project ?

 I check in the API and find the
 qgis.core.QgsMapLayer
 but it is the single layer.

 Also I find the
 qgis.core.QgsLayerTree

 But it seem not only layers but also groups.
 There is a container for all and only layers ?

 Thx,
