Re: [Qgis-user] Georeferencing Raster
When you are replying to a digest, kindly observe standard netiquette and only quote the part of the digest message that is relevant to the discussion. Any activity that involves processing raster images is by definition much more resource intensive than editing vector layers. When you are drawing maps, most of the layers you are likely to be working with are vectors. It is inevitable your system will be much more impacted in performance when processing the raster data than it is for drawing vector layers. The onus is basically on you to ensure you are using a computer system that has good performance specifications.

Re: [Qgis-user] "QgsProcessing" has no attribute 'run' (same for 'processing')
Nice attitude, Hannes :-)
Yes, totally true about the AI trap. You can't write a program by
handing the logic over to a "well read entity"
I use it when my mind is plain out of google keywords.
In maybe half a dozen attempts with AI, I have only hit gold once.
Thanks for the links.

Hi Zoltan,
the most important thing first: Don't fall into the "AI can program"
mindset trap. You *will* end up with nonsense like this if you do.
Those tools can often hallucinate non-existent APIs and mislead you.
They might work for some more basic or wide-spread code bases but so
far I have seen very bad results for PyQGIS. Best search the web using
"pyqgis" as additional keyword to your query.
As https://qgis.org/pyqgis/3.34/core/QgsProcessing.html says, that
class only contains data to be used by Processing things. It is not
your entry point into using Processing via Python.
For that please see
https://docs.qgis.org/3.34/en/docs/user_manual/processing/console.html
, written by actual, smart humans ;)
And for the Batch file: Don't write your own, QGIS comes with a
perfect one already, called |python-qgis[-ltr].bat| . See e.g.
https://gis.stackexchange.com/a/428577/51035
Cheers and good luck!

Hi,
Apologies for asking help on what hopefully might turn out to be
trivial, but I am pretty much blue in the face googling and asking
Gemini for help.
There are 2 questions in this email:
I have a Windows 11 OSGEO4W installation QGIS 3.36.0 and grass (and
more).
I use PyCharm 2023.3.4 (Community Edition) - but not yet configured
"nicely" for QGIS as I am mostly in a non-Open Source environment.
Most of the stuff I write is python is for "problem fixes" and these
python scripts ideally run on a windows command-line with a BAT file.
So, in this scenario below, I keep getting: . *has no
attribute 'run'
*This whether I am running inside PyCharm or on the command-line
through below batch job.
*Question #1*
*What is the correct bat file structure for running python scripts?*
I currently have [below] but is it optimal?
SET QGIS_PATH=C:\OSGeo4W\apps\qgis
call "C:\OSGeo4W\bin\o4w_env.bat"
SET PYTHONPATH=%QGIS_PATH%\python;%PYTHONPATH%
SET PATH=%QGIS_PATH%\bin;%PATH%
C:\OSGeo4W\apps\Python39\python.exe
Z:\Projects\Development\python_QGIS\qgis_tests\qgisrun.py
pause
*Question #2*
I have tried many various import options, but I cannot get past the
*has no attribute 'run'* error from python below code:
Minimalst as this code is, it should run without adding anything
else, should it?
from qgis.core import QgsProcessing
shp_inErfPoly = 'Z:\\Erven_1February2024.shp'
shp_outErfFix = 'Z:\\Erven_1February2024_FixGeo.shp'
QgsProcessing.run("native:fixgeometries", { 'INPUT':
shp_inErfPoly, 'METHOD': 1, 'OUTPUT': shp_outErfFix})
Some pointers on what to do or where to read would be great.
Thanks in advance,
Zoltan

[Qgis-user] Problem with QGIS: Form uniform groups/clusters from a large point data set
Hello everyone, I'm facing a problem that I can't wrap my head around: I have a population dataset in the form of dots. Each point represents one inhabitant within an imaginary grid cell of 100x100 meters. For example, if there are 37 inhabitants living in one grid cell, there are 37 points on top of each other. (The data set is quite large and contains about 4 million points) I would like to divide the point data set into groups of equal size. It is important that the groups are really the same size. (Clustering using k-means etc. does not work for me...) I am also faced with the problem that I would like to try out different variants of group formation.

Re: [Qgis-user] How to catch a QgsMapCanvas::emitExtentsChanged-signal?
Hi Bernhard, what about
iface.mapCanvas().extentsChanged.connect(lambda: print("the extent has
changed!!!"))
Or something more usefull like
def extent_has_changed_slot():
print(iface.mapCanvas().extent())
iface.mapCanvas().extentsChanged.connect(extent_has_changed_slot)
Btw, the *signal* is 'extentsChanged', 'emitExtentsChanged' is a
*function*, which will trigger the emit of the signal.
So:
a) 'xxx' ist the signal-object, above 'iface.mapCanvas().extentsChanged'
b) extentsChanged is a signal without parameters, signals with
parameters can be used in slot-functions with appropriate signatures.
Below a sample for a signal with parameters, see
https://api.qgis.org/api/classQgsMapCanvas.html#a6c6f74644c9b273917a29e77b6400e89
def map_tool_was_set_slot(new_tool,old_tool):
print(new_tool,old_tool)
iface.mapCanvas().mapToolSet.connect(map_tool_was_set_slot)

Hi,
I'm trying to write a plugin, that gets into action, whenever the user moves
or zooms the main map. I found the QgsMapCanvas::emitExtentsChanged() signal.
This is probably exactly, what I need. But I don't know, how to "catch" this
signal. I guess, this is somehow done with pyqtSignals, but I don't understand
how...
I found a tutorial (1) which explains how to use pyqtSignal with self defined
signals. I think I got this. But now I need to catch a signal which is defined
in the library. How to connect to this signal?
From what I understand, my code should be something like:
def __init__():
# with some pyqtSignal xxx:
xxx.connect(my_fun)
def my_fun(some parameters?):
# code to execute when extents changed
So two question remain:
a) What is xxx above?
b) Does "my_fun" need some parameters?
Any help is appreciated!
Thanks, Bernhard

Hi, I'm busy loading a lot of datasets in a Postgis database. For vectordata it is possible to save the QGIS style IN the database. Off course you can save several styles for the same table in the database. But I fail to find a way to choose between those. Am I missing an option? Or is this not yet implemented?

[Qgis-user] Georeferencing Raster
Hello all, my collegue got some trouble with georeferencing raster images. As soon as he activates the tool „LAYER >> GEOREFERENCING“ his system gets very, very slw. It takes plenty of time even to open the raster image and then to set referencing points. While changing the windows between Map and Referencing Tool the windows are getting grey and show „No response“. In the end he doesn‘t know wheter the system is still running or „died“ along the way. I installed QGIS Version 3.34.4 now, but it ist he same behaviour as in hil older version 3.16. Is there maybe a special setting, that can be changed to get a better performance?

May you check? If it is the case, have you set such option for a reason or haven't you set it?

I did this yesterday and it worked fine for me, but my command has:
-f "SQLite" /tmp/xxx/OUTPUT.sqlite
Instead of the -f parameter in your screenshots. I'm not sure how to
change this - can you see any options that let you select this output
format?
I am just wondering whether the two formats you've selected need
additional parameters. The SQLite format appears not to need anything
else.
Cheers,

I tried putting the information in using the field calculator and even though the simple expression seemed correct and there was no error message it did not put the information in. So I was even thinking of putting the information in by hand once sorted although suspect there may be issues with this too. I was wondering about sorting the whole file then copying out/exporting chunks of a million rows at a time to go into a normal spreadsheet. If the copying out/export would not work directly then saving the sorted version of the data and chopping up using e.g. notepad++ and editing with spreadsheet. It is important to do the sorting before chopping up into the 5 separate files. It is only later that spatial information is attached, that is not relevant at this stage as the spatial data will not be attached to all rows. Ok so you are sorting a text file, presumably something like a .CSV. Perhaps you are working on Windows. What are your options to sort the file before you put it in QGIS? It seems your spreadsheet won't accommodate the number of lines in your file; what about the "sort" utility in say Windows PowerShell?

Re: [Qgis-user] editing and saving very large table
Surely this is something that can be done easily with an SQL Select with Order-by, in one of the SQL variants that QGIS can use? I’m asking for my own benefit too. Having come from the MapInfo environment I would reach for an SQL Select to do this task, but I’m less familiar with SQL in QGIS.

Thanks, can you suggest how as the refactor fields help is not clear, to say
the least, about saving after sorting.
I sorted the data (5 million rows) by a couple of the columns, just by clicking
on them, then wanted to save in the new order but this 'save in the new order'
seems impossible.

Hello Michael,
How did you sort the columns? If you have ordered them in the QGIS attribute
table, they will not change their order when you export them. For this, you
must use the "Refactor Fields" tool.

Re: [Qgis-user] question abot shapes
Good morning, I have a PostgreSQL database of several million points with latitude/longitude and I would like to do the following with qgis-server or PostGis: according to a number of shapes (hexagons, circles or squares) per mesh, calculate the number of points per shape and color the shape darker as there are points underneath. If there are no points the shape should not appear. If we zoom in, the meshes must be recalculated and reduced of course. On the other hand I would like a leaflet basemap.

Can you set the annotation to show HTML then use an "img" tag to show an image that's saved in your project folder? e.g. You may not be able to show TIFFs, but if you convert them to .png or .jpg then it should work. I haven't tried this with annotation layers but it works in map tips to have an image appear when you hover over a feature. A quick Google suggests annotation layers have the option to render HTML so I would imagine it would work there too.

Re: [Qgis-user] Adding a Web map to QGIS
Hi Krishna, Can you not ask them to turn on the WFS service in their ARC setup? Unless, like many govt agencies, they just ignore users requests. Sigh. Another option is to look for the data you want in data.gov. I have found that govt agencies often have strange & limited access to their data in-house, but also provide their data to data.gov, where it is more accessible.

[Qgis-user] How to modify (individual) marker properties for a vector layer with many points
Hello,
My code is using the following snippet to plot a vector layer:
vl = QgsVectorLayer("Point", "RadiusField", "memory")
pr = vl.dataProvider()
pr.addAttributes([QgsField("name", QVariant.String),
QgsField("radius", QVariant.Double)])
vl.updateFields()
for idx in range(self.nx):
for idy in range(self.ny):
f = QgsFeature()
f.setGeometry(QgsGeometry.fromPointXY(QgsPointXY(self.phalanx[idx,idy,0],self.phalanx[idx,idy,1])))
punctum = "point_" + str(idx) + "_" + str(idy)
f.setAttributes([punctum, 1.0])
pr.addFeature(f)
vl.updateExtents()
symbol = QgsMarkerSymbol.createSimple({'name': 'circle',
'color': 'yellow'})
vl.renderer().setSymbol(symbol)
vl.triggerRepaint()
QgsProject.instance().addMapLayer(vl)
This plots yellow circles of the same radius at all points as expected.
What I'd like the code to do next is to plot each individual circle with
specific properties. For example, the following modified snippet tries
rendering inside the loop:
vl = QgsVectorLayer("Point", "RadiusField", "memory")
pr = vl.dataProvider()
pr.addAttributes([QgsField("name", QVariant.String),
QgsField("radius", QVariant.Double)])
vl.updateFields()
for idx in range(self.nx):
for idy in range(self.ny):
f = QgsFeature()
f.setGeometry(QgsGeometry.fromPointXY(QgsPointXY(self.phalanx[idx,idy,0],self.phalanx[idx,idy,1])))
punctum = "point_" + str(idx) + "_" + str(idy)
f.setAttributes([punctum, 1.0])
pr.addFeature(f)
if (idx % 2 == 0) and (idy % 2 == 0):
symbol = QgsMarkerSymbol.createSimple({'name':
'circle', 'color': 'yellow'})
elif (idx % 2 == 0):
symbol = QgsMarkerSymbol.createSimple({'name':
'circle', 'color': 'red'})
elif (idy % 2 == 0):
symbol = QgsMarkerSymbol.createSimple({'name':
'circle', 'color': 'green'})
else:
symbol = QgsMarkerSymbol.createSimple({'name':
'circle', 'color': 'pink'})
vl.renderer().setSymbol(symbol)
vl.triggerRepaint()
vl.updateExtents()
QgsProject.instance().addMapLayer(vl)
However, this results in the same output as it repaints everything with
the latter symbol (not to mention that replotting the whole vector layer
over & over becomes expensive).
My main question is whether this is a workable approach (and I need to
figure out how to render marker by marker) or if I should consider using
other classes. I was thinking that maybe QgsMarkerSymbolLayer could be
of use for this problem, but the example from the PyQGIS
DeveloperCookbook seems to use it for constructing new symbols, not to
have variations of the same symbol while drawing many of them. Thanks.

[Qgis-user] QtWidgets.QFileDialog.getSaveFileName make qgis crash on windows 10
Hi,
with qgis 3.34 with a processing script in pythonthe use of the dialog
box QtWidgets.QFileDialog.getSaveFileNamemakes qgis crash on windows 10
and not on windows 11.
Maybe because the dialog is initiated in C/Program Files\QGIS 3.34.4\bin
which is a protected folder?I tried to set the document folder as
default, but same crash.
the code :
output_file_name = input_featuresource.sourceName() + '.kml'
output_file_path, _ = QtWidgets.QFileDialog.getSaveFileName(None,
"Exporter les polygones au format KML",
output_file_name,
"Fichiers KML (*.kml)")
I try this with the same crash when i click "Enregistrer"
output_file_name = input_featuresource.sourceName() + '.kml'
default_directory = os.path.join(os.path.expanduser("~"), "Documents")
output_file_path, _ = QtWidgets.QFileDialog.getSaveFileName(None,
"Exporter les polygones au format KML",
os.path.join(default_directory,output_file_name),
"Fichiers KML (*.kml)")

[Qgis-user] editing and saving very large table
I have a very large (5 million rows) table in qgis and have sorted some of the columns etc and want to save the sorted version but whatever format I try (.csv, geopackage or other formats) it just saves the original order not the sorted order. It also will not allow me to click the button to ‘save edits’ whether or not the table is editable. Trying to copy large chunks of the data out by highlighting it in sorted order is also very flaky – occasionally it works but most often does not. I know a database would be more suitable for doing this but I want to know if this is possible in qgis itself or is simply impossible. ___ QGIS-User mailing list QGIS-User@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
[Qgis-user] "QgsProcessing" has no attribute 'run' (same for 'processing')
Hi,
Apologies for asking help on what hopefully might turn out to be
trivial, but I am pretty much blue in the face googling and asking
Gemini for help.
There are 2 questions in this email:
I have a Windows 11 OSGEO4W installation QGIS 3.36.0 and grass (and more).
I use PyCharm 2023.3.4 (Community Edition) - but not yet configured
"nicely" for QGIS as I am mostly in a non-Open Source environment.
Most of the stuff I write is python is for "problem fixes" and these
python scripts ideally run on a windows command-line with a BAT file.
So, in this scenario below, I keep getting: . *has no
attribute 'run'
*This whether I am running inside PyCharm or on the command-line through
below batch job.
*Question #1*
*What is the correct bat file structure for running python scripts?*
I currently have [below] but is it optimal?
SET QGIS_PATH=C:\OSGeo4W\apps\qgis
call "C:\OSGeo4W\bin\o4w_env.bat"
SET PYTHONPATH=%QGIS_PATH%\python;%PYTHONPATH%
SET PATH=%QGIS_PATH%\bin;%PATH%
C:\OSGeo4W\apps\Python39\python.exe
Z:\Projects\Development\python_QGIS\qgis_tests\qgisrun.py
pause
*Question #2*
I have tried many various import options, but I cannot get past the *has
no attribute 'run'* error from python below code:
Minimalst as this code is, it should run without adding anything else,
should it?
from qgis.core import QgsProcessing
shp_inErfPoly = 'Z:\\Erven_1February2024.shp'
shp_outErfFix = 'Z:\\Erven_1February2024_FixGeo.shp'
QgsProcessing.run("native:fixgeometries", { 'INPUT': shp_inErfPoly,
'METHOD': 1, 'OUTPUT': shp_outErfFix})
Some pointers on what to do or where to read would be great.
Thanks in advance,
Zoltan

Re: [Qgis-user] QGIS and FileGDB
Totò Fiandaca pigrecoinfinito at gmail.com Tue Mar 5 00:15:20 PST 2024 I noticed that by modifying the FileGDBs created by ArcGIS PRO in QGIS: 1. saving is particularly slow; 2. I often lose data, i.e. if I have an active data selection and I try to update only the selection, QGIS updates the entire dataset resulting in data loss. Hi Totò, as you already know, QGIS handles ESRI File Geodatabase layer via the GDAL/OGR library. The GDAL/OGR library has two different drivers for the ESRI File Geodatabase forma: the built-int driver "OpenFileGDB" [1] (which is available on all systems) and the "FileGDB" driver (available on Windows through OSGeo4W) which depends on the ESRI FileGDB API SDK [2]. Using which driver does the issue occurs? How do you update the data? I think you should inform the GDAL/OGR developers about the issue. Since you experience the issue often, it shouldn't be so difficult to provide a sample ESRI File Geodatabase layer and exact steps in order to replicate the issue. Best regards.

This could be one solution, although it might be a bit harder to control the upload settings (because you are trying to upload GeoJSON as the "wrong" MIME type) so it may stop other programs from recognising the files properly as well. Another solution is to work out how to tell the browser or OS that "application/geo+json" should be downloaded rather than viewed. I always had trouble getting this to work properly as it seems to be handled quite differently for each OS (e.g. with Firefox on Linux the settings are in the browser but on Windows it uses the same settings as Windows Explorer). For years I used a Firefox extension that overrode the standard settings and forced most files to be downloaded instead of viewed. You might just have to Google a bit to see if you can work out which settings to change to get a given MIME type (like "application/geo+json") to download instead of open. Sorry I couldn't be of more help!

Re: [Qgis-user] MacOS GeoJSON download from Google bucket
Hi Adam, thank you very much for the feedback. I made following experience since the post. The same file uploaded (using in both cases Chrome) by macOS and then uploaded by windows is resulting in different datatype assignments on the Google bucket. That gives the impression that the OS of the file upload is setting up the data type (text or / binary-download). I will try to find a setting in macOS to setup GeoJSON as binary instead of a text file. Is this the right way to go?

> What are the minimum and recommended hardware requirements for QGIS? For normal application use, a computer that's less than 10 years old is probably fine. I'm running it on a second hand office Dell from 2017 with no issues at all. If your computer is capable of viewing modern web sites then it is capable of running QGIS quite well. These days computers are so fast that outside of some specific fields, pretty much any computer will do the job for most things. QGIS is not a particularly demanding application as far as these things go. > What type of graphics card is required/recommended: OpenGL (Open Graphics > Library), NVIDIA CUDA (Compute Unified Device Architecture), or RTX (Ray > Tracing eXtensions)? If you use any of these things for your work, you will already know exactly what you need. If you have to ask the question, then you are unlikely to need particular support for these technologies. The aforementioned Dell I am using does not have a dedicated video card and is using Intel onboard graphics (one of the most basic setups you can get), and it works just fine with QGIS.

I think this is probably down to the configuration of the web browser and/or the operating system. It's been a while, but you used to be able to configure "helper applications" in the browser settings that controlled what action happens when you open certain files. I guess on one system it has set up GeoJSON as a text file but you want to change it to a binary/download instead. Alternatively when it opens up as a text file you can just save that (e.g. through the File menu) as it will give you the same result.

Re: [Qgis-user] can't apply mask on labels
Hi All The mask option is great but if you cannot use it, I often grab a color using the color picker from the background image and use that as a buffer at 0.7. I choose the color that appears the most in the background image - so sometimes dark and sometimes light.

Re: [Qgis-user] Atlas printing to PDF
Hi Springfield I know lack of time is crazy - but the question here is, will I be using this product over and over again? If that is the case, then I would recommend rebuilding it from scratch if testing the old one fails. Here are some possible options to follow to get to the bottom of this. The first should take no time. First, let's start clean and create a new QGIS profile <https://www.northrivergeographic.com/qgis-profiles/> in your current QGIS and open your product and run it. Are the glitches still there? If so, then it could be your content. If not, then this is an easy fix and you can run your product. Test to see if you can get away with dragging in the old project into the new version and making a few changes. See how it performs and if there are still glitches, you will need to work out where the glitches are coming from. Are they hiding in the template? Test to see if when you bring it in, in a completely clean environment, add in data you wouldn't normally use and run it. If there are no glitches here, then is it something in or associated with your data. Test the data in a clean environment without the template to see how it performs. In regards to the workflow I proposed, you can drag in the data from your old project with all the trimmings if you access it under the old project in the Browser window. You can then recreate the Layout using the template. There are other workarounds too by saving the data as .sld files but as I am writing this, I am really feeling for you. I hope this helps, and you can get your product out.

Or is ther aalternative solution?I'm sure there's a way around the problem. It seems quite unusual.How did you add the polygon initially? That might shed some light onwhy it's there and how to remove it.You don't have any print layouts or anything active?If you don't have any luck, and the project is not confidential, itcould be useful to share it so we can try it for ourselves. You cansave a copy of the project for this, and then delete all the layersfrom the copy so the only thing in the project is the polygon. You mayeven find as you do this the polygon disappears when you delete acertain layer which might give some hints about where it's coming from.Cheers,Adam.QGIS-User mailing listQGIS-User@lists.osgeo.orgList info: https://lists.osgeo.org/mailman/listinfo/qgis-userUnsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user ___ QGIS-User mailing list QGIS-User@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user

[Qgis-user] Inquiry Regarding Hardware Requirements for QGIS
Dear Subscribers, I am interested in obtaining information regarding the minimum and recommended hardware requirements for the QGIS software, used for spatial data analysis. What are the minimum and recommended hardware requirements for QGIS? What technology does the QGIS program utilize for display and computation? Is a single-core CPU, multiple cores, or a different setup used? Is a graphics card used for display and computation? If so, what are the minimum and recommended requirements? What type of graphics card is required/recommended: OpenGL (Open Graphics Library), NVIDIA CUDA (Compute Unified Device Architecture), or RTX (Ray Tracing eXtensions)? Kindly provide answers to the above questions or direct me to where I can find this information. Thank you in advance for your assistance.

Re: [Qgis-user] can't apply mask on labels
Hi all, The mask is more flexible and cartographically more pleasing if you don't have a homogenous single-color background on your map. The mask is the only way to get rid of darker colors while keeping light background colors. See f.e. this example here: https://s.geo.admin.ch/bb5itd6k85y7 Have a look at the large labels "Pfaffhausen", "Benglen", "Schwerzenbach" and "Fällanden". Darker colors from roads (black) and rivers (blue) are masked, but lighter colors from forests, lakes and hillshading are preserved. The mask is the only way to achieve this "selective" effect of masking. All other options like background rectangles or buffers have a fixed color and only work on a homogeneous background. They wouldn't be able to achieve the effect of the example above. I hope this clarifies the difference in the approaches? The only major problems with the masks are the following limitations (hopefully they can be removed in the future): - they cannot be used within the same layer (you need to duplicate layers if you want to mask features with labels from the same layer) - they don't yet work on vector tiles, because vector tiles aren't real QGIS vector layers with all the symbology options. They only have a limited set of symbology so far Greetings, Andreas -- Andreas Neumann QGIS.ORG board member (treasurer) _______ QGIS-User mailing list QGIS-User@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user

This means that if you have more than one connection to the same file (e.g. perhaps two layers coming from the same file, or have it open in QGIS and another program at the same time), there is a risk of the file being corrupted upon write. It sounds like this data format might be one to avoid for datasets you want to modify with QGIS.

Re: [Qgis-user] QGIS and FileGDB
Hi Emma, Thanks for the reply. As I wrote in the initial email, there are many variables at play and I cannot always reproduce the problem, opening an issue in these conditions is not the best choice as it would be closed immediately. I will try to understand the problem better and maybe in the future I will open an issue. I wrote the email so that other users could be careful if they used this format.

If you don't have any luck, and the project is not confidential, it could be useful to share it so we can try it for ourselves. You can save a copy of the project for this, and then delete all the layers from the copy so the only thing in the project is the polygon.

Re: [Qgis-user] Cannot erase a polygon
Is it possible you drew the polygon as an Annotation object instead of an object in your vector layer? Easy enough to do, and they don’t appear in the layers menu.

Re: [Qgis-user] Atlas printing to PDF
Hi Spring I am sorry you are experiencing this. I would strongly advise you to move up to the latest LTR of QGIS 3.36 when you can. It sounds like there are some buggy things happening in the background, so maybe you need a clean version. If this was me, I would follow this workflow. - Open up in the original version and create a .qpt from the print layout - Create a new product in the latest LTR - Locate the old project in the Browser window - Expand that project and drag the files into the new product. - In the print layout: - load the qpt - Copy over the Atlas parameters from your old product (you can have both versions open at the same time) - Run the atlas and see if it works. Good luck!

[Qgis-user] Problem: Can't open Spatialite tables in QGIS on Windows
Hi, We have been using QGIS & Spatialite for years and have recently encountered a problem in QGIS under Windows. We connect to a spatialite database fine, we can list the tables, but when we try to open them we get an error: db <...> table <...> is an invalid layer - not loaded (this is also written to the log) I can open the db in DBManager and enter the query "select * from t_transect;" which runs & shows the data in the output pane. When I try to load the layer as a map layer I get an error message referring me to the error log, but the log is empty. This is using QGIS 3.34.1 on Windows. The same database file works perfectly on Linux, with QGIS v3.34.3. A colleague has tried this & v3.36 on Windows with the same problem. The databases are generated with echo sounder data by the ESP3 application, and we have been able to use these in QGIS for years without problems until now. Spatialite access the tables fine, the basic metadata is present: select * from geometry_columns; t_transect|geom_col|1|2|4326|0 t_echoint_transect_1d|geom_col|1|2|4326|0 The QGIS error message is not particularly helpful in determining the problem. Our workaround is to run the SQL we would have run in the QGIS database manager directly from the spatialite command line, exported to CSV & then open the CSV in QGIS, which works, but is not ideal. For some context about these data: The figure shows each "ping" from the echo sounder, scaled by the magnitude of the echo from fish, showing the location and density of fish encountered on each transect (ESP3 is used for the acoustic analysis). This dataset was from surveying a hill off the west coast of New Zealand (generated on Linux!).

[Qgis-user] QGIS and FileGDB
I use OSGeo4W on win 11 64 bit and got the problem in QGIS 3.28 and 3.34 For work I use both QGIS and ArcGIS PRO 3.2.2, I noticed that by modifying the FileGDBs created by ArcGIS PRO in QGIS: 1. saving is particularly slow; 2. I often lose data, i.e. if I have an active data selection and I try to update only the selection, QGIS updates the entire dataset resulting in data loss. I have already noticed the malfunctioning of FileGDB in QGIS for some time, but I want to leave this trace, unfortunately it is not easy to reproduce.

Re: [Qgis-user] Atlas printing to PDF
Hi Nigel, Okay, note that. However, I cannot get QGIS 3.32.3 to load copies of a couple of my projects. It seemed to hang up while dealing with certain files which I then went back to the original 3.16.4 and removed. Then it would hang up on a different file. In a new project, 3.32.3 will load those files but not from the original project. Is 3.32.3 known to have problems? It seemed to install all right from the Windows .MSI installer. Update: the program will actually load those files, it just takes up 10 min. to do so. And then there are huge delays during the work session. The files loaded individually into a new project with no problem. Once I finally got it working, I was able to try printing the Atlas. No change, it just prints one blank page. No error messages, just a fail. Not sure what the answer is, I don't have the time to keep trying new versions when they are mostly a disappointment. Nevertheless, thanks very much for your thoughts… Cheers, Spring On 2024-03-01 00:22, Nigel Berjak wrote: Hi Spring The rasters should not be a problem.

Re: [Qgis-user] How QGIS handles on-the-fly projection?
There is specific code for QGIS to handle transformation between EPSG:3857 and EPSG:4326 due to EPSG:3857 not being valid at poles. See the comments at https://github.com/qgis/QGIS/blob/master/src/core/proj/ qgscoordinatetransform.cpp#L585 [https://mailtrack.io/l/3b9f0f5d1696eca585d974232660d3c67b88aeef?url=https%3A%2F%2Fgithub.com%2Fqgis%2FQGIS%2Fblob%2Fmaster%2Fsrc%2Fcore%2Fproj%2Fqgscoordinatetransform.cpp%23L585=8747767=160430bc5e3e39b2] You should not be using EPSG:3857 for datasets that span more than +/-85 degrees latitude.

Re: [Qgis-user] Cannot open up projects in 3.36.0
Strange, after waiting about 10 minutes, now my Projects opened up fine, both the ones where I saved in 3.24.1 in the new 3.36.0 format and those created in 3.36.0 from the get-go. Maybe it takes a couple of open/closes after you install 3.36.0 to work well? I did notice the blue status bar at the bottom and have waited until it went away. Maybe my mistake was trying to open files while that blue status bar was just running? For full disclosure, I have both 3.24.1 and 3.36.0 installed, but they’re installed in their own directors. I wouldn’t think they could conflict with one another. Kind of weird.
