Re: [Qgis-user] qgsRelationReferenceWidget

Andrew;
Well that was simple, thank you. I didn't even think to look there; I was
trying to add a standard push button and associate it with save.
Now I just have to solve everything else.
Thanks again.

 Thanks, I don't know what I would do without you! Coding isn't normally
 an issue but that tutorial didn't quite explain where to put the coding.
 When I opened the UI file in IDLE it looked like XML, and there were no
 other files associated with the form. I also opened the "see code" option
 and it was the same looked like XML; it might have been C++ but I have no
 training or experience with C++ so I wouldn't know if it looked similar to
 XML from the "untrained eye" point of view.
 Going to be doing some testing on the versioning bit here this week,
 hope to have something a little more concrete to say about it soon.

Re: [QGIS-it-user] snap e tool muovi elemento

[Marco Spaziani]

A me funziona.
Scusami se mi permetto, ma all'inizio anch'io mi ero impantanato per i
motivi che ora vado a chiederti:
Sei sicuro, prima di attivare Move:
- di aver predisposto le Opzioni di snapping?
- di aver reso editabili (Attiva modifica) sia i layer di partenza che
quelli di destinazione?
- di aver selezionato l'oggetto o gli oggetti (la linea o le linee) che
vuoi traslare?

Hi Christoph,

Thanks for the response.
I will take two steps back and explain what I am trying to accomplish
rather than where I am having trouble.

I have been a professional C/C++ developer, but have never used Python.
(I could learn to write python scripts if required, but they are not
obvious to me - yet)

I have road crash data where, for each road crash, I have a field for
date and a different field for time.  (The data came as csv, I put it
into postgis, but for Time Manager have saved it to a shp file)

The data is updated every couple of months, and starts in 2001.

When looking at road crash data I generally consider crashes in 5 year
groupings. I am wanting to use Time Manager to show the 5 year
groupings, annually.
(There are times I may want to change the length of the groupings, so I
want something where I can easily change from 5 years.  I am currently
dealing only with calender years) 

Using the 5 year groupings, this is I want from Time Manager:

Frame 1 - road crashes 2001 to 2005
Frame 2 - road crashes 2002 to 2006
Frame 3 - road crashes 2003 to 2007
...
Frame 12 - road crashes 2012 to 2016

My understanding is that for this the Time Frame Size is 'one year' as
that is the interval between each frame.  (Correct me if I am wrong)

I have seen a number of sample files, and my intent was to create
5 copies of the data, and offset them to cover a 5 year period in each
(annual) frame.


To make the situation more challenging, I am also thinking of doing a
heatmap rather than just showing individual points.  I do not think I
can create a heatmap using multiple layers.


My fall back solution is that I create a new table / layer that contains
the primary key from my crashes table, the coordinates of the crash and
a year in which to display it.  Because each crash is being displayed in
5 different years, this table would have 5 entries for each crash,
but Time Manager would step through a heatmap for each
year.  

I was hoping I would not need to create a new table.

Thanks again!

Re: [Qgis-user] qGIS crashes when working on rasters

[Nicolas Cadieux]

Hi,

If you are using the latest Qgis on Windows 32 bit, there was apparently a bad 
package a few days ago.  Please download again and reinstall Qgis. I believe 
the problem has been fixed.

Re: [Qgis-user] qGIS crashes when working on rasters

[Tudorache, Marian]

Hi everyone,

I am not sure if this issue was solved but QGIS has a rendering setting which 
allows allow using multiple CPU cores.
I experienced those inexplicable crashes with QGIS 2.10 (Pisa).
After I activated the setting Render layers in parallel using many CPU cores 
and put max cores at 8, everything was fine.
The setting can be found in Settings/Options / Rendering.

So if you have multicore machine takes advantage of this.

I hope this helps.
Marian

Hello,

I am new user here and I would like to ask You for a solution concerning my 
problem.

So...

I downloaded and installed qGIS 2.14.6 LTR. I tried to follow this tutorial 
http://www.qgistutorials.com/en/docs/working_with_terrain.html.

I got the raster, added it to my new project and when I insert the coords for 
Mt. Everest and change a scale I got the message qgis-ltr-bin stopped working. 
And it automatically closed qgis windows. I restarted my computer and try it 
again...and I got the same message.

What can be the issue of this problem?

Thank You very much in advance for helping me out.
