Re: [Qgis-user] All attribute info GONE!

2017-10-04 Per discussione Andreas Neumann 
Hi Merryn, 

A feature in (Q)GIS always consists of geometry AND attributes. So if
your geometries are around, also your attributes should be around. If
you delete a feature, both geometry and attributes are removed for this
particular feature. 

If your attributes are gone, double check if the naming scheme is really
correct. You mentioned that you don't see file extensions in Windows.
You need to enable the display of the file extensions in the windows
explorer to see them. Double check that they have the same basename and
then just one extension (not accidentally two). 

One can delete attribute table columns in the layer properties. But I
don't think one does this by accident.

2017-10-04 Per discussione Andreas Neumann 
Hi Merryn, 

What data formats are you using? 

In case you are using shapefiles - can you check if all the necessary
files are around? Note that a shapefile consists of several files: 

* .shp --> geometry
* .dbf --> attributes (perhaps this file is missing?)
* .prj --> projection info
* .shx --> index file
* potentially more.

All files would have the same name, but they would have different file
extensions. You need at least those two. 

The two most important ones are .shp .dbf 

Greetings, 

Andreas

[Qgis-user] All attribute info GONE!

2017-10-04 Per discussione Merryn Delaney 
I've just got back home from maternity leave. The person who replaced me
was not familiar with mapping softwares. I go back to open QGIS file and I
discover that the main file and associated subfiles have been deleted. I
restore them from the bins but when I open all the vectors are still there
but attribute tables are empty!!! If i zoom to the file it doesn't show
anything. Does anyone know what she could have done and how I can fix it?
Is it possible that she saved as the vector with the same name and
accidentally deleted all the data existing data??

Hi Benjamin,

Just to see if I correctly understand you.

Something along the lines of the selective masking proposal at 
https://github.com/qgis/QGIS-Enhancement-Proposals/issues/63 where one could 
select not only layers, but also symbol levels (symbol layers inside a layer) 
to selectively mask underlying symbol layers.

Unfortunately this isn't implemented yet. Still looking for funders - probably 
something for QGIS 3.2

Is this what you want, or something else?

[Qgis-user] R not working in 2.18, macos Sierra

2017-10-04 Per discussione Howard Frederick 
I've been battling with this since upgrading to Sierra a few days ago -
"This algorithm requires R to be run". Anyone else solved this?

R is working from the terminal, and within RStudio.

Kyngchaos QGIS 2.18.13, R 3.4.1.

The docs unhelpfully suggest modifying the Processing "R Folder" option
which is not available.

My $PATH:

/usr/local/bin

[Qgis-user] Processing toolbox: Import table

2017-10-04 Per discussione Pat Hin 
Hello

 

i am writing some own script within the processing toolbox.

For this i use some data saved in a table ("source_table").

 

Currently i select them manually and import them like the following:

 

##Source_Table=table

layerTable = processing.getObjectFromUri(Source_Table)

 

the code works well but i would prefer to import them automatically without

select them manully. How could this be done?

 

Thx

Pat

you can help me. Thanks.

Re: [Qgis-user] Windows UNC paths in output dir

2017-10-04 Per discussione Patrick Dunford 

You can add a feature request on the Qgis Bugs website:

https://issues.qgis.org

But it is already possible to browse network directories (in Windows you 
just go to the Network area in the file open dialog and browse from there)


However typing the \\servername\share part of the path is a requirement 
for hidden shares as it is not possible to browse them.


So I don't think there is any new functionality needed.

Hi!

I was in digest mode in this list, so I need re-start this thread. Sorry.

Ok, I see when you add manually UNC's to QGIS (tested with 2.18.5 and 
3.0 nighly build) you can browse UNC directories for data input/output.


I think it will more "user friendly", if those network drives will 
show up automatically when you like to add data or output/export data.


Maybe I need forward this question to developer mailing list.

Re: [QGIS-it-user] Qgis3 - il tridimensionale e rendering

2017-10-04 Per discussione G. Allegri 
Giulio, Qgis2threejs va benissimo per cose semplici e per pochi dati. QGIS
3D è progettato per supportare dati anche dati massivi (per risoluzione e/o
estensione), simbologia 3D, e in futuro anche stampe.
Ma cosa più importante, QGIS3D è anche un globo, e su base ellissoidica
(non sferica), quindi usabile a scala globale e con precisione ed
accuratezza geodesica.
