[Qgis-user] Can't Create Shapefile Layer

[Nicholas Maloof]

I'm having trouble creating a shapefile and adding it as a layer to my map.
When I pull up the error message log, it indicates there's a warning, but
nothing describing what happened. When I click on the OGR tab, it
reads "Creation
of OGR data source parcels.shp failed: Failed to create file parcels.shp:
Permission denied."

[Qgis-user] Newby trying to load OSM place search plugin

[Cerasini, Vance S]

Hello,

I am really new to QGIS after coming off 20+ years in the ESRI world.

I loaded the OSM place search plugin, but I can't get the panel to come up.

Can anyone help?

Hi Andreas,

Maybe worth a longer explanation:

0. the O.S. settings are in fact user settings: the user can choose whether
to use a comma, a dot etc. by configuration in the O.S. in user space
1. this changes were necessary to fix bugs introduced by widgets changes in
QGIS that prevented (among other things) to enter doubles for systems where
decimal point was not a dot, this is not a feature but a bug fix
2. the old situation was messy: some widgets in the UI were honoring the
O.S. settings some were not

The current situation tries to remove the inconsistencies (or at least the
majority of them) and leaves to the user the possibility to configure the
system.

There is already,  it's not in QGIS application but in the O.S. settings.

Btw, adding an option to override O.S. settings at the QGIS level is on the
way:

Re: [Qgis-user] QGIS and ESRI's ArcMAp

[Kurt Menke]

Hi Scott,
Off the top of my head, these are some features QGIS has that ArcMap
doesn't have:

   - Live layer effects
   - Blending modes
   - Unique renderers for points like point cluster, point displacement &
   heatmap
   - Unique renderers for polygons like inverted polygons & 2.5D
   - Hillshade renderer for elevation data
   - Much better color picker interface with options not available in ArcMap
   - More unique sub-renders which can be used in combination with the
   above: Geometry generators, outline marker line, outline arrow...
   -
   - Styling dock
   - Support for a much wider array of vector and raster file formats (by
   an order of magnitude) including support for PostGIS, SpatiaLite, MSSQL,
   Oracle, DB2, Geonode...
   - QGIS is 64 bit vs 32 bit for ArcMap
   - QGIS has a significantly larger array of expression functions
   available which are available throughout the interface including data
   defined overrides
   - Global, Project and Layer Variables
   - Virtual Layers
   - In Esri speak what basically  amounts to automatic annotation
   - Multiple maps per project file
   - Preview of valid bounds of a CRS

Re: [Qgis-user] QGIS 3 Processing question

[Jean-Baptiste Desbas]

Hi,

I had the same issue. I had to loop over the output vector layer (child
alg) to feed the sink (main alg). Maybe is not the
simpliest/shortest/fastest, but it works.
Something like that :

o = processing.run(
'qgis:pointsalonglines',
params, context=context, feedback=feedback
)['OUTPUT']

 (sink, dest_id) = self.parameterAsSink(
parameters,
self.OUTPUT,
context,
o.fields,
o.wkbType(),
o.sourceCrs()
)

for f in o.getFeatures()
sink.addFeature(f)


return {'OUTPUT':dest_id}

Re: [Qgis-user] QGIS and ESRI's ArcMAp

[Randal Hale]

Good Morning (Greetings from TN)

It's a really mixed bag as far as capabilities. I say that - I haven't 
used ArcGIS now for a bit except at ones client's office. The big thing 
you'll notice is it's a different workflow (not necessarily one being 
more right over another). So if you try some workflow you're used to in 
ArcGIS you might get a bit frustrated - but I get frustrated now with 
ArcGIS because of my workflows in QGIS.


 * In general all the extensions you're used to are already included.
   So things like the spatial analyst toolset is there already.
 * Probably the 3D environment in Pro is better (but I've never opened
   pro) - but QGIS is gaining momentum.
 * I find the community here is more vibrant - you can send emails on
   Saturday at noon to the listserve and get an answer.

 * I think QGIS is more flexible - but probably 8 years ago I would
   have argued ArcGIS was. I enjoy this software more now.
 * I think the cartography tools are equal and possibly better than
   ArcGIS.
 * Everyone here is more receptive to suggestions. You can file a bug
   report and talk to a person (and not get a  error).

Give it a shot and start playing with it. Do a small project. Style it 
all up - make a PDF. Hopefully you'll like it -  possibly love it.


(look here -> this might help although it refers to an older version of 
QGIS - it's still a great read -

Re: [Qgis-user] QGIS and ESRI's ArcMAp

[Nicolas Cadieux]

Hi,
Hard to answer but I used to be a big MapInfo, AutoCAD Map user.  I usually 
just use ESRI when other have problems I need to trouble shoot.  Now, i am 
almost exclusively QGIS.  Like others say, it would be hard to make a list as 
QGIS aim is not to just do what others do.  It’s not a copy of other softwares.

There are currently two things that I would like to see in QGIS.  The first is 
a good raster calculator capable of dealing rapidly with HUGE rasters that 
can’t fit into memory. (I am talking LiDAR huge over large territory.)  
(Thankfully, the gdal calculator does it but it was more restrictions 
(identical size,CRS, pixel posting..). I AM not sure ESRI has a flexible way of 
doing that.  

ESRI also has the concept of a raster database.  That is not implemented but 
when you think about it, it’s easy to just keep track of the descriptive values 
in another table.

Nicolas

Re: [Qgis-user] qgis 3.2 attribute table thousand separator

[Andreas Neumann]

I have to agree with Tobias here. It is the most annoying new "feature" 
in QGIS 3x - this localizing of numeric values (decimal point and 
thousand separator). It causes many troubles.


Plus: keep in mind that there are countries where several systems are in 
place. It shouldn't be forced on the user by the operating system 
setting. In Switzerland, some cantons use the "point" as decimal 
separator, while in other cantons, they use the "comma".


I would very much appreciate if there could be separate settings how to 
treat decimal point and thousand separator. The current behavior bothers 
me a lot.

Re: [Qgis-user] QGIS and ESRI's ArcMAp

[SEGGIE Graeme]

That will vary on what level of licensing you have for ArcGIS. If you are on a 
Basic license then you will probably find QGIS will fill in quite a lot of gaps 
in your functionality. Off the top of my head these would include Erase / 
Difference geoprocessing and some proximity analysis.
It will also vary accoring to any extensions you have licensed in Arc - so any 
route networking will be available (in QGIS if you have plugins and suitable 
data)) whereas in Arc you would need the Network Anlayst extentsion. Any raster 
analysis is available in QGIS, but requires Spatial Analyst extension in Arc...

Re: [Qgis-user] QGIS and ESRI's ArcMAp

[Andreas Neumann]

Hi Scott,

This is a difficult (and quite open) question.

There are things in ArcGIS that QGIS doesn't have and vice versa. And 
things that are easier in one system or the other.


One difference is that in ArcGIS you often need commercial extensions, 
while in QGIS you don't have to pay, but it has extensions as plugins 
and processing providers (GRASS, SAGA, R, OTB, etc.) for additional tools.


I haven't used ArcGIS for a long time, so I can't give a fair 
comparison. But things I like in QGIS most, is that it is really 
flexible and open, and easy to extend. I also very much like the 
"expression" system and the fact you can use expressions pretty much 
everywhere where you can set a parameter. Also, the cartographic and 
labeling functionalities and map layout options, as well as atlas and 
report serial prints in QGIS are really nice. Starting from version 3, 
also the processing / analysis functions should be much more stable and 
user friendly. However, I heard that cartography is also a strength of 
the ESRI platform.


To be honest, to get a really fair comparison between the two systems, 
this would require a lot of work and still remain a bit subjective.


What aspects of GIS are you interested in? Cartography, editing, data 
management, publication, analysis?


Greetings,

Andreas

What I want is a quick option for people to disable both separators,
without having to dig into details about which locale might offer this.
I think that's the most common request.
For the manual configuration of the group separators, if you can see a
use-case for that I don't mind, I just could not think of one.

Maybe (I've recently messed with that from O.S. settings and got unicode
issues but that might not affect C++ code), but why do you want to loose
the possibility to user your favorite locale's decimal point without having
the group separator?

Will it not work if the last option does QLocale.setDefault(QLocale::c()); ?

The problem is that QLocale does not allow to only format numbers: you get
all from a locale (date, currency etc.) or none, which is not currently a
big problem because we only format dates and numbers (AFAIK), but using
QLocale::setDefault at the application level seems to me the right solution
for the long term.

I'm afraid that the last one requires changes through all the code and the
implementation of custom validators and custom widgets, so I believe it's a
no go, unless we wanted to go back to UI inconsistencies where some widgets
use system locale (scale and coordinates to cite some) and some other don't
and get back to a certain number of bugs that this implementation fixed.


I'm working on my proposed solution, let's see if that suit all needs (I
think it should: at least you should have the "old" behavior with dot and
no group separator without the old inconsistencies).


Btw, there is already a workaround: change your number formatting options
at the operating system level and QGIS will respect your choices.

Re: [Qgis-user] qgis 3.2 attribute table thousand separator

[Claas Leiner]

Hi,

In my opinion, no representation of a thousand separator in the 
attribute table is required. This is confusing for the users. By 
default, the attribute table should show only data, not a representation.

If needed, it can be created using the expression format_number ().

format_number(11615,0) returns 11.615
format_number(11615,2) returns 11.615,00

This is easier than in the operating system settings.

What do you think about a radio button for Number formatting

 - "According to system locale"
 - "According to locale [combobox]"
 - "No formatting"

I believe the last one deserves its quick setting. I am not sure if
someone wants to omit the group separator and have a custom decimal
point, then ok.

I looked into this: the problem is that you can customize the group
separator (thousands) and/or omit it completely but you cannot customize
the decimal point without changing the whole locale (the locale also
defines currency and other settings that are not currently used by QGIS).

So, the best solution here would probably be:

- allow the user to override system locale as a whole (same widget that we
have for the translations)
- add an option to omit the group separator

This way you could set QGIS to have the decimal point from your locale or
from any other locale and you could set it to omit the group separator, but
you would not be able to choose a group separator different from the locale
you selected.

How does it sound?

No: not yet, for now you need to change your operating system settings but
nothing prevents us to implement this as an override in the QGIS options
locale section.

It's operating system and window manager dependent.

Usually under "language/country" settings.

I don't have statistics about the copy operations in the attribute table so
I cannot confirm or deny, sorry.

I guess that in some cases you might want to copy the localized format to
paste it in something used for presentation purposes.

I'd suggest you to open a feature request where we can discuss this issue:
it might be possible to implement it in a copy routine when selecting the
cells in the attribute table.

But again, I'm not 100% sure this is always the desired behavior.

Please note that we have two different localized elements (for floating
numbers) here:
- decimal separator (floating numbers only)
- thousand separator

Re: [Qgis-user] qgis.networkanalysis missing in QGIS 3

[DelazJ]

Hi all,

Karl, what would be nice once you sort out how the network stuff works in
3.x is to provide an update to the docs repository. These docs (actually
most of the Python Cookbook pages) are outdated because we do not have
python writers that would test and provide new information. So if each of
us that has knowledge on an area provides updates on the few he knows, I
think this big issue will be quickly fixed and we avoid people
complain/lose their time on this.

To fix a doc: simply use the FixMe link at the bottom of the page (
https://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/network_analysis.html
in this case) and if you have a github account, modify the text and send a
pull request (guidelines are available at
https://docs.qgis.org/testing/en/docs/documentation_guidelines/first_contribution.html
)
If for any reason you really do not want to create a GitHub account, we
also value raw text: do the changes in a text editor and send it to the
list. Less straightforward for us to integrate but still better than
nothing.

Looking forward

Greetings,
Harrissou

Would it be possible to implement this only to influence the
representation of the number? This is how I see other software
products have solved this issue. Separators being copied is probably
very rarely desired by the user.

Yes: this is new in 3.2 and was aimed to reduce inconsistencies in number
representation though all QGIS application.

QGIS now respects user's locale taken from the operating system settings,
you can choose a different thousand separator or omit it completely by
modifying the settings in your operating system (QGIS restart is required).

Eventually, we could implement these settings as overrides at the
application level for a more fine grained control.

[Qgis-user] qgis 3.2 attribute table thousand separator

[Michael Schulz]

Hi,

short question: in the attribute table of a database (pg) query layer, that
has an integer field, the values are displayed with a thousand separator
(1.003 instead of 1003). Is this new in QGIS 3.2? It's kind of annoying,
because if you copy the value, the separator is copied as well, so you
cannot paste it and use it directly in another query...

Thanks, Michael

[Qgis-user] cadtools QGIS3

[Jonathan ALLAIN]

 
Hello,

Will the CadTools plugins be ported to Qgis3 ?

It's a very useful and effective plugin.

Regards.

Re: [Qgis-user] QGIS 3 Processing question

[Frank Broniewski]

Hi Nyall,

thanks a ton for your response. I am well know for making things tricky for 
myself 😃
Anyway, my testing-algorithm-script is still not working. It runs through, but 
I do not get the expected result loaded into the layer tree. I suppose it runs 
through - the  output from the 'qgis:pointsalonglines' is a QgsVectorLayer - 
but after finishing I get nuthink back.

Here's my complete script: You'll need a temporary polygon layer in a projected 
CRS (I use EPSG:31466) for it to work nicely. Copy & Paste it into a new script 
window and run it. I simply don't find the reason why the point result layer 
isn't loaded into my layer tree ...


from qgis.PyQt.QtCore import QCoreApplication
from qgis.core import (QgsApplication,
   QgsProcessing,
   QgsFeatureSink,
   QgsProcessingAlgorithm,
   QgsProcessingParameterFeatureSource,
   QgsProcessingParameterNumber,
   QgsProcessingParameterFeatureSink)

import processing


class PolygonCenterline(QgsProcessingAlgorithm):

INPUT = 'INPUT'
DISTANCE = 'DISTANCE'
OUTPUT = 'OUTPUT'

def tr(self, text):
return QCoreApplication.translate('Processing', text)

def createInstance(self):
return PolygonCenterline()

def group(self):
return self.tr('Cartography')

def groupId(self):
return 'cartography'

def name(self):
return 'polygoncenterline'

def displayName(self):
return self.tr('Calculate a polygon centerline')

def initAlgorithm(self, config=None):
self.addParameter(
QgsProcessingParameterFeatureSource(
self.INPUT,
self.tr('Vector Polygon Layer'),
[QgsProcessing.TypeVectorPolygon]
)
)

self.addParameter(
QgsProcessingParameterNumber(
self.DISTANCE,
self.tr('Point distance value'),
type=QgsProcessingParameterNumber.Double,
minValue=10.0
)
)

self.addParameter(
QgsProcessingParameterFeatureSink(
self.OUTPUT,
self.tr('Center line')
)
)

def processAlgorithm(self, parameters, context, feedback):
# qgis:pointsalonglines
params = {
'INPUT': parameters[self.INPUT], 
'DISTANCE': parameters[self.DISTANCE],
'START_OFFSET': 0,
'END_OFFSET': 0,
'OUTPUT': 'memory:'
}
points = processing.run(
'qgis:pointsalonglines', 
params, context=context, feedback=feedback
)['OUTPUT']

return {self.OUTPUT: points}

You're making this tricky for yourself! Cut out everything in processAlgorithm 
related to self.INPUT, and just pass the parameter value direct to the child 
algorithm to handle:

[Qgis-user] Weird bug with view in postgresql

[Rémi Desgrange]

Hi,

We are using views to display data « nicely » to user in qgis. This views have 
INSERT/UPDATE/DELETE INSTEAD OF trigger ex: 

CREATE TABLE myCable(
cab_id uuid primary key default uuid_generate_v4(),
cab_usefull_column text,
the_geom geometry(LineString, 2154)
);

CREATE VIEW vw_myCable AS SELECT * FROM myCable;

CREATE FUNCTION f_insert_via_trig_mycable() RETURNS TRIGGER
LANGUAGE plpgsql AS $$
BEGIN 
--useful stuff and finaly
INSERT INTO myCable (cab_id, cab_usefull_column, the_geom) VALUES 
(NEW.cab_id, NEW.cab_usefull, NEW.the_geom);
END;
$$;

CREATE TRIGGER insert_mycable_trig INSTEAD OF INSERT ON myCable FOR EACH ROW 
EXECUTE PROCEDURE f_insert_via_trig_mycable();

Same stuff for update and delete.

Ok so pretty normal stuff. Now the weird part happens. Some person in my org 
(not always the same) tell me that, sometimes (that’s not good… regularly, I 
experienced it myself) when they create (INSERT) or modify (UPDATE) a geometry 
they can’t select it after creation/update. They have to restart Qgis, and this 
is not good ☹. I’m wondering why this stuff happen… Maybe it’s because 
inserting stuff takes long time (db speaking : >100ms, <200ms). They don’t have 
this kind of problem with non-view layer. I activated “log_statement=all” in 
postgresql to see what happen but I cannot activate it all day on production. 
Maybe this is a problem because 


If you have any insight on this… 

In advance thanks.

We are using postgresql 10, but this behavior happens in pg 9.4/9.5 and 9.6 too.


Sincelery, Rémi Desgrange
