Re: [Qgis-user] HTML tags in label expresion on QGIS 2.0.1

2013-10-21 Thread Nathan Woodrow 
Hey,

HTML based labels aren't supported yet.  What you see in the dialog is a
render preview using a QLabel which can handle HTML.  I need to change that
to just use plain text rather then rich text.

It was never supported in any older versions.

[Qgis-user] HTML tags in label expresion on QGIS 2.0.1

2013-10-21 Thread Paulius Litvinas 
Hello list,

 

I tried to use HTML bold tag  for a part of label text in label
expression.

 

HTML tags are properly interpreted and rendered on "Expression based label"
dialog at Output preview, but unfortunately not the same on the map. 

You can see in the image below - red and green areas.

http://img42.com/Hd4Zp

 

Maybe there is some kind of setting to enable this on map render? (I
couldn't find) Or this is a bug?

As I remember this used to work in 1.x versions.

 

Sincerely,

Paul

[Qgis-user] Python Script for Multi-band zonal statistics

2013-10-21 Thread Leo Kris Palao 
Dear QGIS Users,

Often we want to compute for band statistics for our stacked layers (i.e.,
bands 1 to 9). In QGIS, the available plugin for this is the Zonal
Statistics plugin but it only computes for one band at a time, and as we
suspect if our input is a stacked layer the plugin seems to get the average
values for all the stacked layers in a polygon.

So, I searched for some answers in the web, and I found a python script. I
used it and it seems to be working well, but this only works for one band,
So, what I did was to copy the script and change the band number for each
copy. However, this resulted in a very long script, and I think there is a
much better script than this. Can someone help me improve my script. I am
just new to Python. I just completed a basic Python training course.

import qgis.analysis
vectorlayer=qgis.utils.iface.mapCanvas().layer(0)
rasterfile = qgis.utils.iface.mapCanvas().layer(1).source()
zonalstats =
qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(1),1)
zonalstats.calculateStatistics(None)
import qgis.analysis
vectorlayer=qgis.utils.iface.mapCanvas().layer(0)
rasterfile = qgis.utils.iface.mapCanvas().layer(1).source()
zonalstats =
qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(2),2)
zonalstats.calculateStatistics(None)
import qgis.analysis
vectorlayer=qgis.utils.iface.mapCanvas().layer(0)
rasterfile = qgis.utils.iface.mapCanvas().layer(1).source()
zonalstats =
qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(3),3)
zonalstats.calculateStatistics(None)
import qgis.analysis
vectorlayer=qgis.utils.iface.mapCanvas().layer(0)
rasterfile = qgis.utils.iface.mapCanvas().layer(1).source()
zonalstats =
qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(4),4)
zonalstats.calculateStatistics(None)
import qgis.analysis
vectorlayer=qgis.utils.iface.mapCanvas().layer(0)
rasterfile = qgis.utils.iface.mapCanvas().layer(1).source()
zonalstats =
qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(5),5)
zonalstats.calculateStatistics(None)
import qgis.analysis
vectorlayer=qgis.utils.iface.mapCanvas().layer(0)
rasterfile = qgis.utils.iface.mapCanvas().layer(1).source()
zonalstats =
qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(6),6)

rasterfile = qgis.utils.iface.mapCanvas().layer(1).source()
zonalstats =
qgis.analysis.QgsZonalStatistics(vectorlayer,rasterfile,str(7),7)
zonalstats.calculateStatistics(None)

We used this tool most often to determine the average reflectance or
backscatter from our images per zone (polygon).

  I'll try using the API, but I thought when I was going through the

Dear list,

 

We are looking to embark on a project to boost the drawing performance of QGIS 
to greatly decrease screen refresh times by taking advantage of multiple CPU 
cores.  We’re turning to the list to see if this is something that any of you 
(or any organisations you know) would be interested in co-funding.  

 

Besides ourselves, the Swiss QGIS User Group has very kindly offered to fund 
the development.  We are looking to raise approximately €20k in total and are 
looking for minimum donations of €1000 to reduce administrative overhead.  

 

Please contact us if you’d like to help,

Hi Miguel,

the error message that you see is a (Minnesota) Mapserver error message.
Somewhere in the style definitions it expects a number (or not).

This url I get from QGIS in debug mode, and gives you your error:

http://idecan2.grafcan.es/ServicioWMS/EspNat?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=152208.544610834447667,2940195.98510535480454564,692329.70807293173857033,3376338.62686863588169217&SRS=EPSG:32628&WIDTH=670&HEIGHT=541&LAYERS=EENN&STYLES=&FORMAT=image/png&DPI=96&MAP_RESOLUTION=96&TRANSPARENT=TRUE

Bug if I remove the "&DPI=96&MAP_RESOLUTION=96" part from it, I get a map:

http://idecan2.grafcan.es/ServicioWMS/EspNat?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&BBOX=152208.544610834447667,2940195.98510535480454564,692329.70807293173857033,3376338.62686863588169217&SRS=EPSG:32628&WIDTH=670&HEIGHT=541&LAYERS=EENN&STYLES=&FORMAT=image/png

I'm not familiar with the exact WMS-standard, but as most WMS servers I
know (and use) can handle these two query parameters from QGIS, I think
it is a Mapserver configuration problem/error. You cannot let QGIS
remove those params I think.

no, that's not the intended behaviour.

Shared locks for select queries are ok (that's how postgres works) but they
must be released once cursors are closed (or even deleted).

Please, file a ticket on the QGIS trac [1].

If you want to use a different python/sip/pyqt4 than what is in your

"Default" here means the version provided by Ubuntu in the standard

[Qgis-user] Opening view or table using DBManager locks it in postgis

2013-10-21 Thread Alexandre Neto 
Hello all,

While opening postgis tables and views in QGIS 2.0 (windows 7 64bit), I
noticed some different behaviors whether I use DBManager or Add Postgis
Layer.

Opening with DBManager creates lots of locks in postgres (see below), that
are only released when QGIS is closed. During the lock, it seems impossible
to alter specific tables or views.

For instance, having layer "One" and Layer "two" in QGIS, both tables added
from DBManager, I am not being able to run a trigger to update table "two"
whenever I commit a change in a table "one". If layer two is added  using
"Add Postgis Layer" this problem does not occur.

Is this expected?

Best Regards

Alexandre Neto

[Qgis-user] setting name in title bar

2013-10-21 Thread Brent Fraser 
A few months ago I found some info on setting the name of QGIS in the 
title bar (I think it involved an entry in a config (.ini?) file).  But 
now I can't find that information.  Does anyone have any pointers?


Thanks!

Re: [Qgis-user] How can I reset the starting point of a QgsFeatureIterator?

2013-10-21 Thread Stefano Masera 
The reason is to be more fast. 
I think that restart an iterator is more fast than grab a new one from the same 
layer. 
But I don't know if it's true! 
Thanks

Just grab a new iterator. Any reason you want to reuse the same iteratror.

[Qgis-user] Help running SAGA algorithms

2013-10-21 Thread Julian Bogdani 
Hello all,
I'm trying to run saga algorithms (Kriging) on QGIS, MacOS X (10.6.8) (and Win, 
7) without success.
I've installed latest QGIS from KyngChaos site.
Saga seems to be installed correctly.
Here is the message I get:
Oooops! The following output layers could not be open

Grid: /Users/jbogdani/Desktop/gis/one.tif
Variance: /Users/jbogdani/Desktop/gis/two.tif
The above files could not be opened, which probably indicates that they were 
not correctly produced by the executed algorithm

Checking the log information might help you see why those layers were not 
created as expected

This algorithm requires SAGA to be run. A test to check if SAGA is correctly 
installed and configured in your system has been performed, with the following 
result:

SAGA seems to be correctly installed and configured

Thank you

Re: [Qgis-user] Topological editing of two vector layers

2013-10-21 Thread Alexandre Neto 
Hello Deon,

If you have the chance, exporting both your layers to Postgres\Postgis,
would allow you to, for each district geometry, run ST_Snap[1] against its
related province geometry. With the correct tolerance, this might solve a
big part of your Boundary differences.

Even tho, you would need to check the result and correct the rest of the
problems manually.

Best regards,

Alexandre Neto

Re: [Qgis-user] QGIS 2 and interlis format

2013-10-21 Thread Stefan Keller 
Yes, it's probably not compiled by default under Linux because of it's
dependency to a Java runtime.
In addition, the Interlis 2 driver is incomplete.
There is a project underway which delivers a new Interlis 1 and 2 driver
end of this year (without Java dependency).

Yours, S.

Hi,

Most probably GDAL is not built with Interlis driver. There are lots of OGR
formats which are not built by default and Interlis seems to be one of those

[Qgis-user] QGIS 2 and interlis format

2013-10-21 Thread Daniel . Gnerre 
Hi all, 

I would like to display interlis data in QGIS 2, but I can't find the 
format in the list of vector data formats. In QGIS 1.8, the format is in 
the list (INTERLIS 1 [OGR]). OGR supports this format, why does QGIS 2 not 
? I tried to display all files *.* and select an itf file, but QGIS 2 
fires an error.

QGIS version : 2.0.1
QGDAL/OGR version : 1.10.0

Thanks, 

Daniel

Re: [Qgis-user] Export map to pdf defective

2013-10-21 Thread Andreas Neumann 

Hi Nelson,

This is probably not a bug. It sounds like you have the Atlas serial 
printing active. In the print composer have a look at the "Atlas 
Generation" panel and make sure it is not enabled.


Hope this helps.

Dear Sirs.,

First of all congratularions for the new Quantum GIS 2.0.

I was playing with it last friday, October 18yh., succeeded in
georreferencing high resolution satelite images, very happy. When I
decided to export the map I constructed made to pdf format, there was
a series of at least 10 (ten) maps generated, one of the whole map I
made and the others were fragments of the main map, each of them from
a different map of the "mother map". Can you solve this bug?

Thanks in advance,

Sincerely,

Re: [Qgis-user] Topological editing of two vector layers

2013-10-21 Thread Harish 
If the layers are digitized by different agencies and dissolving is time
consuming for each next higher level, then the automatic snapping of
boundaries within tolerance distance, with keeping one layer as correct
layer will be a useful feature.
