Re: [Qgis-user] OTB Plugin Activation

[Martin Bittens via Qgis-user]

Hello Nicolas,

thanks a lot for your advice. The OTB-plugin is working now. I must
admit that I made a mistake when I tried entering the path to the OTB
binaries. I clicked directly on the respective OTB fields in the
processing --> settings --> OTB tab (e.g., 'OTB application folder'). As
I wrote nothing happened then. But I had to move the cursor in the white
space beside the fields and double click there. Then a menu opened where
I could enter/select the correct OTB paths

Again, many thanks


Martin

Hi,

I am currently with QGIS 3.22.2. my version of the OrfeoToolbox
provider is 2.12.99. Under Processing Toolbox/options/providers/OTB, I
see OTB application folder. It is set to
C:/OTB-7.4.0-Win64/lib/otb/applications.  OTB folder is set to
C:/OTB-7.4.0-Win64.  If you don't have the right folders, it will not
work.  I see no "activate box".  Set the folder then click ok. Close
the Option panel and reopen it to make sure the setting have been
accepted.   If the first folder was the most complicated to set correctly.

5. Opening the Options --> Processing --> Providers --> OTB

But there the "Activate' checkbox  did not appear.


Does anybody know is going wrong?

Many thanks for your help.

Re: [Qgis-user] QGIS 3.22 - GRASS Init-Error

[Martin Bittens]

Hello Allister,

I just installed the latest nightly version of QGIS 3.22 (which is
3.22.0.76) using the OSGEO4W installer. This version is working with the
GRASS 7 plugin and the GRASS 7 algorithms.


Regards


Martin

Hello Alister,

in the meantime I did an update on a second computer from QGIS 3.20.3

installer. The result is:

QGIS 3.22.0 displays the GRASS init error, the GRASS 7 plugin cannot
be used, the GRASS processing algorithms are working.

QGIS 3.16.13 is working without any problems. Both, the GRASS 7 plugin
and the GRASS processing algorithms can be used.


As far as I understood the GRASS 7 plugin in QGIS 3.22 'want to see' a
GRASS version which is not installed whereas the GRASS 7 plugin which
came with QGIS 3.16.13 is satisfied with the installed GRASS version.
But I do not have any idea how telling the GRASS 7 plugin of QGIS 3.22
that it should take what is installed.

I installed 3.22 today using the standalone Windows installer, not
the OSGEO4W installer, and I got the same error on startup.
Both the Grass Plugin and Provider show in the plugin manager as
loaded, but I haven't tried using them to confirm it is truly broken.
I note that the Grass processing algorithms do still work.

Re: [Qgis-user] QGIS 3.22 - GRASS Init-Error

[Martin Bittens]

Hello Andrea,

thanks a lot for your fast response.

1.) Package information

I took the version numbers from the' QGIS --> Help --> about window and
from the plugin manager.

Here are the package information from the network installer:

GRASS GIS: 7.8.6-6;

GRASS plugin for QGIS: 3.22.0-4

GRASS plugin for QGIS (long term release): 3.16.13-1

QGIS Desktop (long term release): 3.16.3-1

QGIS Desktop: 3.22.0-4


2.) Installation

I came from QGIS 3.20 (in this versions I did not receive the mentioned
error message, the GRASS plugin was working well) and did the update
without creating a new directory. The fresh install I did when I made
the upgrade from QGIS 3.18 to 3.20.


Regards


Martin

Hi Martin,
these version numbers are really strange.

I'm referring to the version numbers of the packages that you will see
in the OSGeo4W Network Installer you used to update QGIS.
Those version numbers are in the form of qgis 3.22.0-4, qgis-ltr
qgis-ltr 3.16.13-1, ...

Could you please check again?

Anyway, are you sure you are not mixing packages from old v1 OSGeo4W
repository and new v2 OSGeo4W repository as stated in the QGIS Web site:
"CAUTION: Upgrades of old setups using the new repository are not
supported. You need to do a fresh install or use a different directory."

Re: [Qgis-user] Raster Layer Symbology Problem

[Martin Bittens]

Hello Sebastian,

thank you for your response. Yes indeed, for me the coloring style you
showed would be an option. This style is what I get in GRASS GIS as
well. But,

what I would prefer in QGIS is this (as provided by QGIS 3.16.4 LTR):


So I hope that in future QGIS versions, the user will have the choice
between the different display options. As far as I understood the
discussions in the links you sent there is something going on in order
to add an option for selecting the new  or the old display style.
Unfortunately, I am not an expert in that programming stuff and
therefore I don't know how to apply what there is explained. I will wait
and see what the next QGIS versions offer for displaying raster gradient
legends. And I will keep the QGIS 3.16.4 LTR with special care not
loosing the display style I showed above.

Martin,
I agree with your assessment.
I assume the assumption of the designers (thank you Nyall Dawson et al
for all of your amazing work) was that if you were displaying a
continuous raster you would want a continuous legend as well.
As shown by your issue and in the links I shared with you the reality
is that this doesn't fit all use cases.
I am considering writing up a feature request to address those issues.
Unless you want to?
To help me understand your use case more would a legend that was
continuous but had numerical values at each "break" work for you? An
example of this is in this tutorial

continuum is a new feature in QGIS 3.18 which replaced the
previous method displaying data in the legend as categories (as
QGIS 3.16.4 is still doing - fortunately. Otherwise it would be
difficult producing maps in ongoing projects in a consistent
layout). And obviously there is no option available switching
between the old and the new display method. Personally I think it
was not a good decision giving up completely the categorical
display in the legend. In particular if you would work with
multiple colors and a large range of values, there is no way to
allocate map colors to the corresponding values, or vice versa.

So, I hope that the next QGIS version will include an option which
allows selecting the method how to  display the data, as continuum
or categorized.

[Qgis-user] Raster Layer Symbology Problem

[Martin Bittens]

Hello QGIS User List,

I already sent this message but it was not posted, so it is here again.
Hopefully it works now.


I am still struggling with the problem creating a legend for a raster
layer. Usually I am working with the following settings in order to
colorize a calculated raster layer (e.g. after applying v.surf.idw on a
point data set):

- rendering type: singleband pseudocolor

- interpolation: linear

- mode: equal interval


In QGIS 3.18.0:

Selecting an appropriate color ramp and applying a classification in,
e.g., 5 classes, I see in the "Layer Properties - Symbology" window the
5 colored classes separately and the corresponding 5 values (in my case
temperatures) for each color coding. But in the "Layer Panel" the legend
shows the color coding as a continuum and only the first and last value
of the value range appears. The same thing happens in the layout manager
when I create a layout for printing which includes a legend.

In QGIS 3.16.4 LTR and previous versions:

Doing the same I get the 5 color classes separately and the
corresponding values for each of the 5 classes in the "Legend Panel"as
well as in the layout manger.


My question: Is this a bug in the new QGIS version or does QGIS 3.18 not
provide this functionality anymore?


Thanks a lot for a comment.


Regards


Martin

[Qgis-user] Layer Properties - Symbology

[Martin Bittens]

Hello QGIS Users,

I just got some problems creating a legend for a raster layer. Usually I
am working with the following settings in order to colorize a calculated
raster layer (e.g. after applying v.surf.idw on a point data set):

- rendering type: singleband pseudocolor

- interpolation: linear

- mode: equal interval


In QGIS 3.18.0:

Selecting an appropriate color ramp and applying a classification, e.g.,
5 classes, I can see in the "Layer Properties - Symbology" window the 5
classes with color labels and the corresponding 5 values for each class.
But in the "Layer Panel" the legend shows only the first and last value
of the value range. The same thing happens in the layout manager when I
create a layout for printing which includes a legend.

In QGIS 3.16.4 LTR and previous versions:

Doing the same I get the 5 color classes with the corresponding values
for each of the 5 classes in the "Legend Panel"as well as in the layout
manger.

In my first attempt submitting this message to the QGIS user list I
attached 2 screenshots depicting the problem. But the files were too big
and the list moderator didn't  approve. I hope the problem description
only by words is sufficient.

My question: Is this a bug in the new QGIS version or does QGIS 3.18 not
provide this functionality anymore?


Thanks a lot for a comment.


Regards


Martin

[Qgis-user] QGIS 3.18/3.16.4 LTR

[Martin Bittens]

Hello QGIS users,

I just read the messages about  the latest release of the QGIS 3.18.0
and QGIS 3.16.4 (LTR) packages and must admit that now I am a bit
confused. A couple of days ago I already made an update of my existing
QGIS installation (3.10 and 3.14) using the  network installer
osgeo4w-setup-x86_64.exe which I downloaded from the QGIS homepage. As
usual I selected 'Advanced Installation', the update run without any
problems, and at the end I got the updated QGIS versions 3.18.0 and
3.16.4. But now I read this (e.g.):

Long story short: you cannot upgrade from old installs and have to remove and
reinstall or use a separate directory.  As the new OSGeo4W only supports 64bit
the default root directory was changed to C:\OSGeo4W, which might help with
that if you were on 64bit earlier.

Also note that it now only has one version of Python - namely 3.9, which
doesn't support Windows 7 anymore.  Other updates include Qt 5.15, GDAL 3.2,
PROJ 7.2 and SAGA 7.8.


What does it mean,

- you cannot upgrade from old installs (I did it with success as far I
could see. My QGIS-projects set-up with older QGIS versions are running
obviously without any problems.

- it now only has one version of Python - namely 3.9 (I checked my QGIS
installation, there is no Python 3.9).

- Other updates include ...  SAGA 7.8 (in the package list I could only
see SAGA 2.3.2 LTR and SAGA 2.1.2.)


It would be great if somebody can explain what these messages like
mentioned above are about.

Thank you very much.


Martin

Just to understand, why this path has been defined in the installations

"RStudio" and "QGIS with GRASS"?

Re: [Qgis-user] PDF Georefernces

[Martin Bittens]

Hello Warren,

if you have some  locations in the pdf-file with known coordinates you
can do the following (for me this procedure works fine in most of the
cases):

1.) Convert the pdf-file into *.tif or *.jpg;

2.) In QGIS open the georeferencer tool (you can find it in the raster
tab of the QGIS main window);

3.) Import the *.tif/*.jpg file  into the georeferencer tool;

4.) Add the coordinates of the known locations into the imported map by
using the "add point" button on top;

5.) Open "Settings --> Transformation Settings", complete the setting
options, and click on "OK";

6.) Click on "Start Georeferencing" (the green triangle on top);


Then you should get what you wanted...!


Regards


Martin

Re: [Qgis-user] QGIS 3 Frozen

[Martin Bittens]

Hello Colleagues,

here an update about problems with the plugin manager (as described in 
my previous email):


By incidence I discovered that my internet connection via the wifi 
router changed from 2.4GHz to 5GHz. That means I did the download and 
installation of the QGIS updates using the 5GHz connection (without any 
problems). Starting QGIS and trying to open the plugin manger led to a 
frozen QGIS, as already mentioned. Just because I didn't get any idea 
how to solve the problem I switched the internet connection back to 
2.4GHZ (remembering that in the past I always used this connection and 
didn't get any problems with the plugin manager).


The result: In QGIS 3.7.0 and 3.6.0 the plugin manager is working, in 
QGIS 3.4.5 I got this:



The 'Copy Report' button is greyed out, creation of a report does not work.


Can anybody give an explanation what is going on with QGIS?

I do not understand:

1.) why the use of the plugin manager is depending on the type of the 
internet connection (2.4GHz/5GHz) and


2.) why QGIS 3.4.5 is crashing anyway independent if I am using a 2.4GHz 
or a 5GHz connection?



Thank you for your help.

[Qgis-user] QGIS 3 Frozen

[Martin Bittens]

Hello Colleagues,

After I made the latest update I don´t get access to the plugin manager. 
Clicking on 'Plugins - Manage and Install Plugins...' QGIS stops to 
work. No error message appears, and to close QGIS I need to use the 
windows task manager. Currently, there are 3 QGIS versions on my computer:


QGIS 3.4.5

QGIS 3.6.0

QGIS 3.7.0

The result is always the same. QGIS is frozen.

I am working with Windows 10.

Does anybody know what is the reason for that error?

Thank your for your help.



Martin

Re: [Qgis-user] QGIS 3.4.2/GRASS

[Martin Bittens]

Luigi Pirelli,

thank you so much for your hints.

My QGIS 3.4.2 /GRASS installation is as follows:

I am not sure if these settings are those you want to see. If you do 
need more, please let me know.


As far as I understood the QGIS 3.4.2 settings GRASS 7.4.2 should be 
used. After I read your comment on the path issues I checked the 
/apps/grass folder. 3 different versions are installed there:


grass-6.4.3

grass-7.4.2

grass-7.7.svn

In accordance to your advice I removed the .svn term from the GRASS 7.7 
folder name and - it works. I can use now the GRASS commands in QGIS 
3.4.2. Additionally I changed in the same way the folder name in the 
grass77svn.bat and the related env.bat using GRASS 7.7.svn as a 
stand-alone application as well.


I am  wondering which GRASS version QGIS 3.4.2 actually is using? 
Unfortunately in the QGIS 3.4.2 menu 
Settings/Options/Processing/Providers/GRASS there is no longer an option 
available that allows to define the path to the correct GRASS version 
(as it was in QGIS 3.2.1 - which was my last QGIS 3 version).


Best regards

Martin

in your case this path is grass-svn => bang! trying to convert it as

the fix is simple, but please share more about what is your qgis

[Qgis-user] Wrong Path

[Martin Bittens]

Hello, good afternoon.

I got some trouble with the OSGeo4W Shell after I did the latest QGIS 
update (to QGIS 2.18.24 64bit). Some of the Shell commands I'd use in 
the past do not work anymore.


E.g., for checking the installed python packages: pip freeze --> Fatal 
error in launcher: Unable to create process using 
'"c:\osgeo4~1\bin\python.exe" 
"C:\OSGeo4W64\apps\Python27\Scripts\pip.exe" ';


or

installing a new package: pip install geopy --> Fatal error in launcher: 
Unable to create process using '"c:\osgeo4~1\bin\python.exe" 
"C:\OSGeo4W64\apps\Python27\Scripts\pip.exe" install geopy'.


Interestingly I can use the pip command if I type at the Shell prompt: 
c:\OSGeo4W64\bin\python.exe "C:\OSGeo4W64\apps\Python27\Scripts\pip.exe" 
install geopy. Then the installation process is running correctly.


I do not know why "\osgeo4~1" appears in the path although the setting 
is: set osgeo4w --> OSGEO4W_ROOT=C:\OSGeo4W64


QGIS is installed in the directory C:\OSGeo4W64, OS: Windows 10.


Does anybody know a solution for that problem?


Thank you very for your advice.


Martin

[Qgis-user] Provider Error

[Martin Bittens]

Hello QGIS Users.


I want to create a text field in an attribute table which contains some 
data points by using the field calculator. So I selected:



- Create a new field

- Output field name: Comment

- Output field type: Text (string)

- Output field length: 10

- Text input: 'Area 2'


The Output preview shows: 'Area 2'. By clicking on "OK" I receive the 
following message: "Could not add the new field to the provider"


My system is: Windows 10, QGIS2.18.21.

In the previous versions of QGIS I did not get that error when I added 
with the field calculator text fields in attribute tables.


Does somebody know a solution solving the error?


Thank you very much.


Martin

[Qgis-user] QGIS 3.0.1

[Martin Bittens]

Hello, dear QGIS-Users.

Today I tried to install the latest version of QGIS (QGIS 3.1, 64bit 
network installation). The download and the installation process worked 
fine, but the post-install stopped at "/etc/postinstall/qgis.bat". I 
could only click on "Cancel" to finish the installation what led to an 
uncompleted, not working QGIS. I tried also the express installation but 
got the same result. The installation stopped as soon as the 
post-install started. My computer is a Win10-64bit machine. Under Win7 
which I am running in a virtual machine on the same computer the QGIS3 
installation worked perfect without any problems.


Does anybody know how I can solve the problem?

Thank you for your help.

[Qgis-user] QGIS 2.99 - GRASS

[Martin Bittens]

Hello, friends of QGIS.

Since a couple of days I am trying to solve a problem I got with the 
GRASS modules provided in the processing toolbox of QGIS 2.99 (latest 
download today). After downloading the latest 2.99 version I got an 
error message when I open a GRASS module. It's like this:


WARNING    Traceback (most recent call last):
              File 
"C:/OSGEO4~1/apps/qgis-dev/./python/plugins\processing\gui\ProcessingToolbox.py", 
line 269, in executeAlgorithm

              File 
"C:/OSGEO4~1/apps/qgis-dev/./python/plugins\processing\algs\grass7\Grass7Algorithm.py",

                'GRASS 7\nfolder is correctly 
configured'.format(os.path.join(path, 'bin')))

            NameError: name 'path' is not defined

GRASS 7.2.2 is installed (the settings menu shows: 
C:/OSGeo4W64/apps/grass/grass-7.2.2) and the GRASS 7.2.2 plugin is 
working fine. My Windows system: Windows 10 Professional, 64-Bit.


Btw.: with the QGIS version I had used before I downloaded the above 
mentioned version (as far as I remember I installed the previous version 
sometime in November or December 2017) the GRASS modules did work fine.


Does anybody get an idea what is going wrong?

Thank your for your help.


Martin

[Qgis-user] QGIS 2.18

[Martin Bittens]

Dear QGIS Community.

I am using the QGIS versions 2.18 (32bit and 64bit). Recently I noticed 
that the panel with the processing toolbox does not show anymore the 
button which can be used to switch between the simplified and advanced 
view. As far as I remember after the first installation of QGIS, on the 
bottom of the panel appeared something (written in blue color) like 
'...add a new provider, simple view, or close'. I clicked on close, and 
then these options never came back. Does anybody know how to reactivate 
this settings?


Thank you so much.

Regards

Martin

[Qgis-user] Field Calculator

[Martin Bittens]

Hello QGIS-Users

I am running the QGIS 2.13.0-Master (32bit) on a Windows 7 machine. The 
problem I am not able to solve is the following: the field calculator 
does not display the "Selected Function Help" window. It was there in 
one of the previous QGIS versions, but now it got lost. Any ideas how to 
solve that problem?


Thanks a lot
