Re: [Qgis-user] Import lines from cvs

2016-01-07 Thread Joris Hintjens 
Thanks, Nicolas, but
already tried that: all CRS is 4326. Zoom to layer does nothing. 
Should I change the E and WE, N and S to pos and neg?

Re: [Qgis-user] SAGA Add Grid Value to point

2016-01-07 Thread Victor Olaya 
Lene

SAGA algorithms using several raster layers must use rasters with the
same extent and cellsize, so they match. In SAGA terminology, they
must use the same grid system

Certain algorithms do not need that (as it is in your case), but that
has to be explicitely stated in the algorithm definition. It seems
that we forgot to add that in this case.

I have added the AllowUnmatching tag for that algorithm and the Add
grid values to shapes as well

It is available in master

Hope this helps.

Cheers!

Re: [Qgis-user] Import lines from cvs

2016-01-07 Thread Nicolas Cadieux 
Hi, 
Are you sure you have no features or are they just it the wrong place?  
Right Click on the layer and select zoom to layer extent.  Check your CRS 
and make sure you have CRS on the fly activated.  Make sure your option 
don't automatically assign the project or default CRS  layer as your layer 
does not have one yet.

This is relatively straightforward in QGIS master: 

- import your CSV file 
- right click the CSV layer, and choose "Save as" 
- change format to "ESRI Shapefile". Choose the correct CRS for your 
coordinates. 
- expand out the "Geometry" group and change "Geometry type" 
from 
"Automatic" to "LineString" 
- click OK, the new LineString shapefile (with all null geometries) 
will be added to the project 
- now, you need to create the geometries. This is done through the 
field calculator. 
- tick "update existing field" 
- change the field to "" 
- enter the expression: 
'make_line(make_point("x1","y1"),make_point("x2","y2"))'
 (but replace 
x1, y1, ... with the correct columns names from your original CSV 
file) 
- click OK. Done!

Re: [Qgis-user] starting QGIS desktop

2016-01-07 Thread Phil (The Geek) Wyatt 
Give it time Peter - it will load eventually. Very much depends on your
computer.

 

If it never loads then yes, do a reinstall. I think if you try a reinstall
in the same directory it will find the older installation and ask do you
want it removed.

 

There is now a version 2.12.2

 

Cheers - Phil

Desktop 2.12.1 point to \program files\QGIS Lyon\bin\nircmd.exe.  When I

the message "restoring loaded plugins", which can take a couple of minutes.
I am about to reinstall unless someone has a better idea.  To reinstall do I
start with the preremove.bat or use the uninstall in the Windows Control

Hi, 
Can you see QGIS.bat in your QGIS program file directory?  Try clicking on 
that.  Could it be an anti virus? Try deactivating it.  
With the easy installer, you can use the windows control panel. 
Do you have many plugins activated?  Try removing them from the .QGIS 
directory found in your personal user folder.  Active hidden file and 
folder in windows to see it.

[Qgis-user] Problem with spatial selection on Spatialite spatial view in QGIS

2016-01-07 Thread Richard Males 
spatialite_gui 1.8.0 devel
QGIS 2.12.2-Lyon

For work I am doing in developing a model of coastal flooding, I use
spatialite as the underlying data store for the location and attributes of
structures in a coastal region.

In my spatialite database, I have a table with geometry (Assets), and a
related table with attributes (StructureAssets) but no geometry.   I make a
spatial join via the query/view composer, joining the geometry and
attributes into a spatial view.   I can use this view as a data source in
QGIS, it plots perfectly.   However, when I attempt to select by a
rectangle on the view, the selected points are all over the place, not in
the drawn rectangle.  If I export the view via the spatialite gui as a
shapefile, then selection on the shape file based on the view is fine.
When I create a table in spatialite from the view, and import that table
into QGIS, it shows the same selection behavior as the view, i.e. no good.

Any ideas or thoughts for further testing will be welcome.
Thanks in advance.

This is relatively straightforward in QGIS master:

- import your CSV file
- right click the CSV layer, and choose "Save as"
- change format to "ESRI Shapefile". Choose the correct CRS for your
coordinates.
- expand out the "Geometry" group and change "Geometry type" from
"Automatic" to "LineString"
- click OK, the new LineString shapefile (with all null geometries)
will be added to the project
- now, you need to create the geometries. This is done through the
field calculator.
- tick "update existing field"
- change the field to ""
- enter the _expression_:
'make_line(make_point("x1","y1"),make_point("x2","y2"))' (but replace
x1, y1, ... with the correct columns names from your original CSV
file)
- click OK. Done!

Re: [Qgis-user] Import lines from cvs

2016-01-07 Thread Joris Hintjens 
Thanks Nyall,

I try to understand your procedure, but…:

line3: “save as…”: Before doing that, I already need a geometry defined, a 
proces you describe later i the process. I don’t get it.
line 4: "- expand out the "Geometry” group…”  This is an option from the “load 
csv layer”, not from “save layer as (shape)”
line 8: change field to : which field?  I lost you there completely. 
Sorry.

Re: [Qgis-user] Import lines from cvs

2016-01-07 Thread Joris Hintjens 
Thanks Nicolas,

But…
Trying to avoid python, as I am illiterate in that field (for now)

For the plugins P2one etc, in order to use that, I need separate lines for 
“From” and “To” points, but I can create them. That will be my next guess, 
after trying the other proposed solutions.
