Re: [Qgis-user] Population genetic data depicted with pie chart QGIS

[Richard McDonnell]

Giulia,
Not used it much, but had a look in *Layer Properties* under *Diagrams*, 
This will allow you to create Pie Charts you are looking for, in 
relation to size, you may have to play around with the settings, but 
there is a *Size* tab in diagrams, utilise *Scaled size*, pick your 
corresponding *Attribute*, click *Find* beside *Maximum Value* and set 
your *Size* *Scale* factor. Hope that helps!!


Regards,

Richard.

Dear all,

I would like to use qgis to depict data derived from population

I'm working with 7 different txt files (one for each sampling

-latitude of the sampling location
-longitude of the sampling locaction
-genetic clades identified in each sampling location
-n° of individuals belonging to each clade

I would like that each sampling location/txt file has got a pie chart 
as marker with slice of different colours (according to the differents 
clades) and different size (according to the number of individulas for 
each clade).


I'm working in a Windows 10 laptop with QGIS 2.14.2 Essen.
Is there anyone that can explain me how to do it?

Thank you very much in advance.
Best regards,
Giulia

Re: [Qgis-user] qgscodeeditorhtml (used in lizmap plugin) missing in ubuntu trusty qgis 2.14.3 package

[Daniel Vicente Lühr Sierra]

In case anyone is interested, I have made some few tests (with success) 
adding a fallback line into qgis.gui.__init__.py:


try:
from qgis._gui import QgsCodeEditor
except:
from CodeEditorPatch import *

CodeEditorPatch is a "pure-python" module which mimics the CodeEditor 
class (and derivatives) implementation as much as possible (there are 
two workarounds for some event handling issues which I haven't been able 
incorporate without errors, and there is some code regarding case 
sensitivity for the SQL editor, which apparently is not possible/needed 
to implement in python).


I think this patch is appealing, because it will provide a (temporal) 
centralized solution, without having to modify each plugin which decides 
to use these classes. Also, it will target two active ubuntu LTRs (12.04 
and 14.04) plus some debian and mint versions.


The moment the missing sip files in qscintilla issue is fixed, this 
patch can be removed.


If someone is interested in the module I can share the code, or I guess 
I could make a pull-request if some people think it is a good idea.

That's because of missing qsci sip files in trusty.  See #12011[0]

Missed this one.

db_manager uses a workaround that could probably be adapted for
the lizmap plugin too.
I found it too, and I was testing some alternative. I was able to call 
the Scintilla editor directly in python and set it up for HTML syntax 
(2 lines of code). Could it be a fallback for the PyQgis API, when the 
c++ signatures fail? Because, even though the sip files  might not be 
present, the python scintilla class is available, and it could work 
for all QgsCodeEditor derived classes.


Thanks.

What happen when you click the button Connect in the Information GPS Panel?
Is connected successfully (green state)?

Did you have more than an app in system accessing to the GPS port?

In my case, GPS port work per app, if you need more then one app using GPS
port you need to clone the port with app like localizer (
https://www.centrafuse.com/us/newproducts) or gpsgate (
http://gpsgate.com/products/gpsgate_client)


I hope this help.

This is somewhat like our "late" release announcements.   We (now) announce
when binaries are available and not when the actual release happens (ie.
release branch, release tag, tarball).

And the website names the version LTR that is in the LTR package repositries
and not the one that is in the regular repositories - although it currently is
a LTR as well.

And that the new LTR (that didn't see any extra maintanance yet) doesn't
replace the old LTR right away was a conscious decision - but a bit influenced
by the build scripts usually dealing with two different parallel releases and
resolving what to do when there's just one.   Doing it like this IMHO is better
than just leaving one repository age or feeding both with same stuff.

Re: [Qgis-user] Next LTR RElease

[Neumann, Andreas]

Hi, 

There is a lot of confusion around the LTR version. Just to make it
clear: 2.14 will be advertised as LTR when 2.16 is released. The reason
is, that in order to be stable enough to be called an LTR it should
receive 2-3 bug fixing rounds. Many bug fixes that go into 2.16 are also
backported to 2.14x. 

So expect 2.14 to be advertised as LTR once 2.16 is out - probably in
the second week of July. 

Hope this helps to clarify.

Re: [Qgis-user] Next LTR RElease

[Matthias Kuhn]

Hi Jonathan,

You can find the roadmap here, yes 2.14 is an LTR.
https://www.qgis.org/en/site/getinvolved/development/roadmap.html#release-schedule

The update on the page should happen in a week. My point of view
regarding this topic can be found here:
http://gis.stackexchange.com/a/188243/9839

While this may not reflect the official position of the project (if
there's any) and while the current windows release names may more be a
side-effect of release scripts than a conscious decision I pretty much
like the added maintenance time (cooldown period).

Cheers
Matthias

I'd suggest that should probably be updated to state that 2.14 is an LTR too.

[Qgis-user] Qgis - Big Postgis layer - open attribute table takes a life to execute

[Rossin Pietro]

Hello list
I'm facing a problem with qgis (2.14.3)  and postgis multipolygon layer.
This layer is a "big" (2200 records) dataset, with id, geom and other 4 columns 
( character varying(n) )
Id is serial primary key and there is an Index on geom using gist.
The dimension of this layer as shp is 17.5MB (16.3 MB shp and 1.2MB dbf)
If I load the shape file in qgis it loads quick and the attribute table too (it 
has to be so because it's on my filesystem..).
As Postgis layer it takes much longer to load the geometry in TOC but it takes 
a huge amount of time to open the attribute table.

I took a look at network data transfer between the open attribute data table 
(not geometry display) and the complete load and 32MB are downloaded.. It takes 
at least 1 minute to open the table (5 columns, 2173 records) with qgis 
freezing until load
Then I made a try to union all polygons with same attributes so a layer with 16 
rows is generated, same problem , almost 32MB data transfer and a huge time to 
load the attribute table.

In PgAdmin a select like
SELECT id, field1, field2, field3, field4  FROM mytable;
Takes 700ms to return 2173 records

SELECT DISTINCT field1, field2, field3, field4  FROM mytable;
Takes 42ms to execute and return 16 rows

So, what happens with QGis and attribute data table? It seems that all the 
table geometry column included is loaded if data attribute is requested...

Is there some setting I miss to setup in preferences?

Thanks
Pietro Rossin

I have a point file and a line file. I want to move all non-intersecting
points to the line position closest to them. Does QGIS have a tool for
that? Is there a plugin?
Cheers
Tyler

Emne: Re: [Qgis-user] Open MapInfo Workspace Plugin

Hi Lene,
 I don't know why, but all plugins from French Ministry of Ecology disappeared 
from QGIS main repository. Maybe something related to recent publication 
workflow changes?
Anyway, the ministry has a dedicated repository here:
http://piece-jointe-carto.developpement-durable.gouv.fr/NAT002/QGIS/plugins/plugins.xml

just add it to your QGIS plugin manager and you will find back openwor plugin.

Hi,
I have got a question about opening a MapInfo Workspace.

Previously there was a plugin OpenWor – Can´t find it

How do I get all the colorizing from a workspace into QGIS ?

OK I found that. But then the whole layer becomes the selected color to
the entire edges of the planet. And there is no way to undo short of
closing qgis and not saving. As CTRL+Z does not work.

Re: [QGIS-it-user] da fiume poligono a fiume linea centrale

[Gabriela Osaci Costache]

Grazie di cuore, Pierluigi! E' davvero utilissimo: in un solo passaggio si 
ottiene lo strato con la linea desiderata (ho modificato i parametri inziali 
per thin e smoothness). Poi si esporta lo strato per utilizzarlo in 
QGIS...sbaglio...in gvSIG, perché lì c'è un modulo (in Sextante) che calcola 
automaticamente l'indice di sinuosità e altre proprietà geometriche delle linee 
(molto tempo fa Paolo ha aperto un ticket  per avere le stesse funzionalità in 
Processing...).

 Il modulo v.voronoi con l'opzione skeleton (-s) l'ho trovato soltanto in GRASS 
7.0.4, usato indipendentemente da QGIS. Per rispondere alla domanda di Paolo: 
purtroppo non c'è in processing (GRASS), ma non so inglese per aprire il ticket 
:-(
Mi sembra una funzionalità molto utile...e difficile da trovare :-(. Si 
potrebbe introdurre nel "cuore" di QGIS con una denominazione suggestiva?

Grazie ancora,Gabriela

Ciao,
anche io mi sono trovato ad affrontare lo stesso problema.Adesso il nuovo 
modulo di GRASS v.voronoi con l'opzione skeleton (-s)
Fa quello che dici tu direttamente da geometria vettoriale, evitando la 
conversione in raster poi r.thin e la riconversione in vettore.
GrazieP

In PostGIS 2.2.0+ c'e' una ST_ApproximateMedialAxis, puoi provare
quella:

[QGIS-it-user] Installazione QGIS su Mac

[FILIPELLO GORIA]

Buongiorno a tutti,
vorrei scaricare QGIS, però mi è sorto un dubbio, perché non ho visto elencata, 
fra le versioni disponibili, la versione installata sul mio MacBook, ovvero  OS 
X El Capitan 10.11.5.

Sapreste cortesemente indicarmi se il download è compatibile?

Eventualmente potreste mandarmi un link di download?

Ho provato a lanciare il download di QGIS dal sito, in realtà dalla pagina 
ufficiale sono stato reindirizzato in una pagina “in stile orientale”, ma il 
tempo di download stimato mi è sembrato troppo lungo, oltre 8 ore per 280 Mb 
circa, perciò ho interrotto.

Grazie, cortili saluti,
Roberto Filipello

Re: [Qgis-user] regularly spaced address markers on alternating side of road

[Dan Jacobson]

Thanks. The idea is every 25 meters there should be a (proposed) house
number (location) on the left, then one on the right, left, etc.
Making for a total of 20 + 20 = 40 per kilometer.
Sort of like what I did with GRASS years ago
http://jidanni.org/geo/house_numbering/mountain.html
but clearer via using two sides of the roads... but just putting them
all down the middle would be OK too. Yes, it would be good to avoid
depending on plugins.
In fact just a bunch of dots along the center of the road would be fine,
which then I suppose I could hack the .qgs file to add labels to with a
perl script which I thankfully know how to write. I'll just remind the
government workers to remember odd goes on the left, etc.

Veramente interessante questo "Eqdistant line plugin".
Grazie per la dritta.

Re: [Qgis-user] regularly spaced address markers on alternating side of road

[Neumann, Andreas]

Hi Dan, 

Interesting problem. 

Are these regularly spaced or should they appear at given vertices of
the input vector line? 

I was thinking that maybe one could use a marker line, with dynamic font
markers - but unfortunately there are no "per feature iterators" or
"counters" available in the QGIS expressions. If these would be
available, it would be an easy task. 

Also, the labeling options, combined with the geometry expressions are
pretty powerful and dynamic, but again - without iterators ... 

Geometry generators also come to my mind, but again - without iterators
in QGIS expressions we are blocked. 

- 

I am forwarding this to the dev list to see if someone has an idea - of
course with Python there would be options ...
