Re: [Qgis-user] large DEM not loading tiles correctly

[Patrick Dunford via Qgis-user]

I think you are referring to XYZ tiles which are 256x256 pixels. These 
are designed to be put onto a web server and served through WMTS to a 
client. Is that the kind of application you are using them in?

they are ascii grid basically numbers so should not have any .jpg 
issues. It is unfortunate that they chose to make the grid file so 
difficult to use by chopping it into the many thousands of small 
squares each within its own folder within other folders within other 
folder.

Hello

This is a raster format? and how large are the tiles?

I spend a lot of time working with raster files often a few thousand 
at a time. There doesn't seem to be a problem displaying them in Qgis 
unless they are Progressive Jpeg format, which in more recent years 
seem to have an issue with one of the third party libraries Qgis uses 
to import with.

It is particularly odd that some of the tiles will merge and

then they will load and display (in addition to the hundreds

Yes, I know pip install is quite a barrier, I've been using this plugin for
years and never used the standard console again.

I guess this is more a personal project than a plugin for a wider audience.

I'm glad that you've found it useful.

Re: [Qgis-user] large DEM not loading tiles correctly

[Richard McDonnell via Qgis-user]

Hi,
So the underlying data might not be very efficient, for example, no internal 
Tiling, or compressions used.
What I would suggest is…


1.   Create a VRT of all the data you have.

2.   Using GDAL Translate convert the VRT into a GeoTiff, with the following

a.   NoData Value of -

b.   Advanced Parameters

   i.  
NUM_THREADS = ALL_CPUS

 ii.  BIGTIFF = 
YES

   iii.  TILED = YES

   iv.  COMPRESS = 
LZW

c.   Data Type to Float32

3.   You can then also use Pyramids for your Maximum zoom levels, I 
recommend external, as they can be deleted if you want to change them.

I hope that goes some wat to helping.
Kind Regards,

Richard.

Ciao Stefano,
non penso che "ignora" renda l'idea di "override". Prova a leggere 
"Ignora il percorso della cartella in uscita temporanea" facendo finta 
che non sai a cosa serva questa opzione. A me non pare che abbia il 
significato corretto.


Ho fatto un ricerca in Transifex e "override" è tradotto in italiano 
moltissime volte con derivati del verbo "sovrascrivere", alcune volte di 
"sostituire" e poche volte di "ignorare".


Io penso che, in generale, usare "ignorare" per "override" sia errato, 
mentre sia più comprensibile "sostituire" o "modificare". Infatti 
quell'opzione, come hai visto, serve semplicemente a modificare il 
percorso della cartella temporanea.


Ah... visto che ci sono... ho notato che "Skip output" (un opzione dei 
layer di output negli algoritmi di processing che serve ad evitare che 
un particolare layer di output venga creato) è tradotto in italiano, in 
QGIS, nello stesso identico contesto, alcune volte con "Salta risultato" 
e altre con "Risultato non disponibile": penso che questa seconda 
traduzione non corrisponda al significato.
Nella documentazione, "Skip output" è invece tradotto in diversi modi: 
"Ignora risultato", "Tralascia risultato", "Nessun risultato", 
"Risultato non disponibile", "Non dà risultato", e anche "Predefinito: 
Skip output".


A presto.

[Qgis-user] Live Online Training Course: An Introduction To Integrating QGIS/GIS And R For Spatial Analysis - 31st October - 3rd November 2022

[Colin D. MacLeod via Qgis-user]

We are now taking bookings for the next run of our live, online course 
titled _An Introduction To Integrating QGIS/GIS and R For Spatial 
Analysis_. It will be held via the Zoom online video-conferencing 
platform between the 31st October and the 3rd November 2022.


The course will consist of a mix of background talks and practical 
sessions held over four 3-hour sessions. One session needs to be 
completed each day, and attendees will have a choice of completing it 
between 10:00 and 13:00 UK Time (primarily aimed at those in Australia, 
Asia, Africa and Europe) or between 19:00 and 22:00 UK Time (primarily 
aimed at those in North, Central and South America). This allows the 
course to be as accessible from as many different time zones as 
possible.


Attendance will be limited to a maximum of 24 people per session. It 
will cost GBP 295 per person (with a discounted rate of GBP 245 for 
students, the unwaged and those working for registered charities). To 
book a place, or for more information, visit 
http://gisinecology.com/online-course-an-introduction-to-integrating-qgis-gis-and-r-for-spatial-analysis/ 
or email i...@gisinecology.com.


This course is aimed at those who wish to learn how to use and integrate 
QGIS (the leading freely available GIS software package) and R (the 
leading freely available data analysis software package) for spatial 
analysis. It will be taught by Dr. Colin D. MacLeod, the author of 'An 
Introduction To Integrating QGIS And R for Spatial Analysis [1]' 
(Pictish Beast Publications) and a renowned expert in using GIS in 
biological and ecological research. He is also a co-author of the 
recently published 'An Introduction To Basic Statistics For Biologists 
Using R [2]', which is a practical guide to carrying out the analysis of 
biological data in R. The course assumes no prior knowledge of either 
QGIS/GIS or R, and so is open to complete beginners as well as those how 
know how to use one of these software packages, and wish to learn how to 
integrate it with the other.


GIS and statistical analysis are two of the most fundamental software 
tools for modern biologists wishing to conduct spatial analyses. 
However, each have their own sets of software packages, and sometimes it 
can be difficult to know how to integrate the two. This course will 
provide an introduction to the integration of QGIS (the leading freely 
available GIS software package) and R (the leading data analysis 
software packages used by biologists) to create a combined tool set that 
makes the most of the strengths of each of these individual software 
packages. It will consist of a series of background sessions on using 
GIS and R for spatial analysis, mixed in with practical sessions where 
you will learn how to use QGIS, how to use R, and how to integrate two 
to complete a spatial analysis project. This last part will include 
working through an example project, starting with creating a high 
quality map for publication through creating raster data layers of 
environmental variables, joining data together based on their spatial 
relationships and analysing the combined data set using R (including 
creating summary statistics, conducting linear regressions and 
conducting generalised additive modelling - GAMs). While it will 
primarily be based around QGIS, this course is taught using 
software-independent approach, and it is also open to those who wish to 
learn how to use ArcGIS to do biological GIS.


When you attend this course you will receive a free copy of An 
Introduction To Integrating QGIS And R for Spatial Analysis [1] (GIS For 
Biologists Workbooks) as the practical exercises in that course are 
based on the ones contained in that book. NOTE: If you wish to use 
ArcGIS software for this course, alternative materials will be provided 
for the practical sessions.

We use clipping paths heavily in the elevation plots, so if we exported 
these to SVG
then the clipping would be ignored and the results would be an unusable 
mess.


If the clipPath element is used for clipping, then the following might 
be of interest.


Came across a limitation in Qt regarding SVG for marker symbols 
recently:

https://github.com/qgis/QGIS/issues/50208

Julien investigated and opened a ticket at Qt:
https://bugreports.qt.io/browse/QTBUG-106720

The outcome was that Qt uses SVG Tiny, which includes only a subset of 
the features included in the SVG Full spec.


Looks like the clipPath element is not supported by SVG Tiny:
https://www.w3.org/TR/SVGTiny/#sec-eleind

Don't know if there are any plans to support SVG Full in Qt, from the 
ticket linked above I didn't got this impression.


Maybe there's a way to use something else instead of clipPath for 
clipping, which is supported by SVG Tiny.


Cheers Björn

Override temporary output folder path =  Ignora il percorso della cartella
in uscita temporanea

può andare bene?

Re: [Qgis-user] PR review needed

[WhereGroup]

Thank you! I had that in my tabs to try out and did so yesterday. It is 
impressive but of course requires the user to manually install some 
packages (which is a HUGE blocker for 99% of users) and is missing 
integration in the script editor. I will probably still use it for 
myself though so thank you very much!

I can't say just how awesome it would be to have some "proper"
autocompletion in the console and editor. One that knows about the
actual object it is used on instead of suggesting random text
string matches from anywhere in its database.

Honestly, this would make learning and teaching Python and the
PyQGIS API infinitely easier and fun.

Seeing the GIFs on https://yoannqdq.github.io/qgis-better-editor/
makes me jealous of the people who used your plugin when it was
working in the older versions. Wow!

Cheers, Hannes

Hi everyone,

Some 2 years ago, I was frustrated with some of the features of
the embedded python console, so I developed a plugin called
Better Editor (https://plugins.qgis.org/plugins/bettereditor)
which offered smart brackets / parenthesis, better toggle comment
action, code formatting with black, jedi autocompletion...

I was quite happy with it, but unfortunately, this plugin was
heavily reliant on monkey patching existing classes, so it broke
very often across QGIS versions.

I'm now trying to backport some of the features I developed in
the plugin in QGIS, starting (small) with the toggle comment action.

I'd be really thankful if a QGIS maintainer could take the time
to review my PR:

https://github.com/qgis/QGIS/pull/50341
