Hi Niccolo',
which backend are you using? In QGIS we have seveal ways of doing this,
and speed differences may be huge. Please also specify which OS and QGIS
version.
All the best.

Re: [Qgis-user] View menu items missing on Master

[Frank Sokolic]

I've rebooted by computer and the menu items have reappeared in the View menu. 
Not sure why they disappeared.

Re: [Qgis-user] qgis-plugin-grass

[Alex M]

At this time it is not possible. The QGIS GRASS Plugin is currently
being rewritten for compatibility with GRASS 7, and is expected back in
QGIS 2.12

I think you need to build/install nightlies or master in order to test
this functionality:

Hi,

is there any possibility how to install plugin for GRASS 7 from
UbuntuGIS repository (for QGIS 2.10)? I just found package
`qgis-plugin-grass` with content which points to GRASS 6.

Thanks, Martin

[Qgis-user] QML reference, symbolize synonyms alike

[Schweitzer, Peter]

Is there a QML reference document?

What I really want to do is specify that two different category values
will have the same symbol, like this:


I want to read this as

when the value of the attribute is EITHER "carbonate rock" OR
"carbonate", render the feature using the symbol named "64"

But this does not have the effect that I want, so I'm thinking
incorrectly about how the QML file works.

I would welcome advice on how to do what I want, or direction to the
QML reference, or both.

Thanks!

Peter

[Qgis-user] Handling large datasets in 2.10.1

[Niccolo' Marchi]

Hi all,
can anyone explain to me how QGIS handles large datasets (both raster 
and vector)? I mean: is there a "limit" connected to the SW or other?


I had very slow responses (a matter of hours) in two cases: clipping 
some UAV images bigger than 1Gb (5cm resolution, 112ha) and merging all 
the features of a shapefile (53000 geometries, almost 350Mb).


This happened on a laptop (dual core 1,7 GHz, 8Gb RAM) and on a 
workstation (quad core 2,13 GHz, 12 Gb RAM)...and I solved quite easily 
with ArcMap :/


any hint?

All the best!

Nic

Re: [Qgis-user] Job opportunity: Open Source GIS / WebGIS / Database developer at NINA, Norway - urgent

[Blumentrath, Stefan]

Dear all,

I just want to inform you, that we are happy that we got a lot of promising 
candidates for the vacant position(s) and are therefore now closing the 
application window.
Thanks to all applicants for your interest in working in NINA and for your 
swift reply! You will be informed about the further process individually...

Kind regards,
Stefan

Subject: [Qgis-user] Job opportunity: Open Source GIS / WebGIS / Database 
developer at NINA, Norway - urgent

Hi all,

At the Norwegian Institute for Nature Research (NINA, 
www.nina.no) there is a vacant permanent position at our 
database-IT department in Trondheim with a special focus on FOSS GIS 
technology, because NINA is planning to take another step into that direction:

see: 
http://www.nina.no/english/News/News-article/ArticleId/3894/Two-exciting-positions-as-database-and-system-developer

That means, the person to be employed would become a key person in building up 
that technology branch in our institute. Unfortunately, the deadline for 
applications expired even before it was properly announced. Therefore we would 
be still happy to receive further applications, though they will have to be 
send swiftly, I am afraid. A good CV and a short letter of application will be 
sufficient... A swift reply is more important than fancy layout or wording of 
your application...

About NINA:
NINA is a diverse research institute covering many different fields of nature 
research (in addition to biologists and ecologists we have economists, social 
scientists, veterinaries ...). NINA has a wide portfolio of projects, so our 
future employee will definitely not suffer from monotony. Being a foreigner 
here in Norway myself, I can warmly recommend NINA and Norway as a place to 
work, also in terms of wages and social security. Of course, nature here is 
fantastic and climate and light conditions are more pleasant than one might 
probably think from the outside ;-)...

We are looking forward to hearing from good candidates and are happy to answer 
questions about the position. Feel free to contact also me via mail or mobile 
+47 40 46 21 15, also during this weekend.

Kind regards,
Stefan Blumentrath
