Re: [Qgis-user] QGIS 3.4.2 still very slow to work in Windows 10

2018-12-12 Thread Patrick Dunford

I run the latest 3.4.x on Linux which has been very stable and reliable.

It will be a while before 3.x is as mature and dependable as 2.x which 
was at 2.18 a very mature product that had been operating a good number 
of years.


Used to run the development version 2.99 but these days I view "stable" 
as effectively development simply because other users (not me) have 
lodged reports for hundreds of bugs that are progressing only slowly.


I wanted the new features in 3.x and would not go back to 2.18 now.

You said you "reverted" to 2.18. On Windows, you can easily run 3.x

really your personal installation that fails, I think.


The node tool was redesigned in 3.x, and there is quite a discussion 
going on, cause not so many people like the new behaviour.


In general, I would like to say, that the promotion of the newest 
release shown in QGIS is quite a bad idea: The inexperienced will not 
hesitate to update and therefore run in every possible bug, being left 
clueless, while the more experienced are more cautious and install it 
only anlongside for testing purposes first.


The developers are in a bad situation: They need lots of testers to 
find bugs, but in my opinion they reach the wrong users with that 
advertisement. (no idea how to improve this)


Furthermore, the new version had a bad start, cause (as I understood) 
last-minute-changes in dependencies caught them unprepared.


Unfortunately, no one gives warnings about the major issues somewhere 
prominently e.g. on the QGIS.org website, so you have to read the 
mailing-list(s) and search in the issue queue yourself. In my opinion, 
in QGIS3 the developers were a little too ambitious, but it seems they 
also had kind of bad luck as well. Lots of features introduced are 
somewhat bleeding-edge and need time to ripe.


As I rarely use Windows, I'm not of big help. I just want to recommend 
you to use the network installer (advanced install!) and install the 
2.x LTR and the 3.x LTR in parallel and update them through the 
installer once in a while, and keep 2.18 for productive work as long 
as you do not trust the 3.x version.


The open source mantra is "release early, release often", but that 
doesn't mean that everyone has to update early and often as well!

If you have enough resources running it in a VM is an option and can be 
a linux version, very stable and very resource efficient


I used to have a bg stack of VMs running all sorts of versions when I 
used to run the development version more than I do now, it was almost 
seamless

I have had to keep quiet about it lately.
I was somewhat relieved to hear a comment on a recent video of the Oceania
meeting that QGIS 3.4.1 was a dud release as it caused Windows to crash at
random moments. I had thought that all the long pauses, messages of QGIS not
responding, and crashing when being closed down was some awful feature
unique to my computer. I had even tried reverting to 2.18 for a while.
However, after I upgraded to 3.4.2 I still had problems.
Opening QGIS on Windows 10 can take over half a minute before anything
happens apart from the outline box of the QGIS window full of blank space.
Once a project finally loads up any random operation can still get the "QGIS
not responding" message.
This can result in further issues because I try pressing buttons to get a
response.
I even bought Anita's 4th edition of "Learn QGIS" to see if I was doing
something radically wrong. It did highlight a few wrinkles until I got to
page 55 when I discovered instructions on the edit node tool. This tool I
had used OK in the past, but it now baffles me totally. I cannot get it to
do what the book says.
I am now losing my confidence in 3.4.2 and can only hope that the next point
release will produce improvements.
It would really help if known major issues like this could be posted here,
perhaps as a sticky which stays at the top, to let users know that they are
not alone with an issue.
Sorry to complain.

[Qgis-user] associate images with a shape file

2018-12-12 Thread Dave Ormerod
Hi I want to associate images with a shape file which I can then open. I am 
trying to use actions to do this but am not getting anywhere. I have a field 
with the file location as a text field. I have tried an open file and also 
tried running an application neither of which seem to produce a result. It 
works on a Mac but not on Windows 10? I am running version 3.4. Thanks David

Plenty of bugs are being discovered and reported but not many bug 
reports are being opened, as it appears to me.


I'm not aware of issues with the new node editor. It works very well 
most of the time.


Qgis 3.4.anything is very stable on Debian, I stopped running it on 
Windows a long time ago.

[Qgis-user] GRASS doesn't import layer from various CRS gpkg

2018-12-12 Thread Carlos Cerdán
Hi group:

Here whit QGIS: 3.4.2 - Ubuntu 18.04.

I can't import a polygon from a gpkg file to GRASS as QGIS plugin. Message
is: "Detected different projections of input layers. Input layers must be
imported separately". Gpkg file has one GEO and two UTM layers, and I was
trying to import one UTM layer. Perhaps GRASS have read the wrong place, so
It refuse to import a layer from a geopackage with different CRS layers.

Developers please take note about it.

Cheers

Carlos

Most of the supported formats come from the gdal/ogr library. It might
be good to inquire with that project. https://www.gdal.org/

That does not rule out the possibility that someone might write a tool
to read the format but it's more likely to come via OGR.

Thanks,
Alex

Full QGIS, so a Windows or Linux tablet?
OR

Hi,

This is a topic that usually gets a lot of response.   If it does not 
get answers this time, you will find some in the archive from earlier 
this year if I recall well.

[Qgis-user] QGIS packaging for macOS: helping crowd-funding campaign

2018-12-12 Thread Saber Razmjooei
Dear QGIS users,

We have been working on a prototype for QGIS packages for macOS [1]. The
feedback we received was generally positive. Some users have reported a
number of issues. We have asked QGIS PSC and they have agreed to eventually
publish the signed packages as the official macOS packages on qgis.org.

There are a number of tickets and improvements which we'd like to do,
before incorporating it to the QGIS.org. For that, we are running a
crowd-funding campaign. More details can be found here:

https://www.lutraconsulting.co.uk/crowdfunding/macos-qgis/

If you are a macOS user, please consider helping this campaign.

Regards
Saber

[Qgis-user] IFC data in QGIS?

Hi
Are there any plans on adding support for reading IFC data
(https://en.wikipedia.org/wiki/Industry_Foundation_Classes) in QGIS? That
would help bridge the gap between the GIS/BIM/CAD worlds.

[Qgis-user] QGIS 3.4.2 Layer Groups and Themes

2018-12-12 Thread afi - Steffen Flörke-Sowa
Hello,
I'm using QGIS 3.4.2. I'm working many times with themes and groups.
Im seein an un unexpected behaviour:
I have my layers structured in a group with two subgroups. All Layers in the 
subgroups are checked, also the main group. I would create two themes: one with 
subgroup 1 active, one with subgroup2 active. So I unchecked the visibility of 
subgroup2 and clicked "add theme" theme1. I did the same for theme2 with 
subgroup1. When I changed to theme1 or theme2, I got the following result:
The visibility of both subgroups were checked, but the visibilities of the 
layers in the subgroups were unchecked. For theme1 the visibilities of the 
layers in subgroup2 and for  theme2 the visibilities of the layers in subgroup 
1 were unchecked. So the map was ok, but the checking of the visibilities in 
the layer panel was irritating and unexpected.  I would like to know if this 
behaviour is intended or not. 

Greetings

Steffen Flörke-Sowa
