Sorry ...forgot to mention that I was using Qgis master version 9e5b889 for
the above test.

Re: [Qgis-user] Union Tool - Ftools/Sextante - How should the real result be

[vinayan]

Hi Victor,

Sorry for the late reply. Thanks for the fix. Now for the second case
described in my question, it works well. The results are correct as per the
explanation by Bernhard.

Now for the first case, the results are not correct. Please see the before
and after results from a simple shapefile. There are two issues. First, the
left and right half circles are not created in the result. The polygons are
not splitting among each other as can be seen from the color differences in
the result.

Note - this is probably due to the iterator getting closed when issuing a
getFeaturebyId request..although I am not sure..
Do you want me to file a ticked for this?

 

Thanks
Vinayan

Re: [Qgis-user] move files with qgis actions

[Nathan Woodrow]

Hey Lito,

In your batch file you can use the MOVE command
http://www.computerhope.com/movehlp.htm

If you have a batch file like:

MOVE %1 C:\Temp\

%1 is the first arg passed to the batch file

In QGIS you would have a action that calls the batch file like this

yourbatch.bat [% ImageField %]

Bump.
Anyone? I'd love to try this and test it, but can't if I have no idea how
to even connect. Is there any documentation for it anywhere?
Thanks,

[Qgis-user] update composer and export as png, using python

[Raymond Nijssen]

For creating a map animation I've made a python script that updates my 
layer's subset filter many times. It also updates my mapCanvas and the 
title label in my composer.


Now I'd like to automatically update the map in my composer as well, and 
export my entire composer as a png file afterwards.


I've been checking the cookbook and (c++) api docs very well but really 
cannot find a way that works...


Hoping any one can help.

Thanks,
Raymond

[Qgis-user] R script with graphical interface under SEXTANTE

[Amon-ra]

Dear all,

I need to use R (2.15) scripts under sextante to give the results (spatial
data) to QGIS.
My R scripts use many libraries to create BBNs, to change BBNs with
graphical tools and load data and spatial data.

For now, I can only open temporary (less than 1 second) my R script main
frame with this :
## [goupTest]=group

source("c:\folder\main.R")

I found many tutorials to know how I can write a short R script with some
sextante commands but not really if I can call an entire R script software
with a graphical interface under sextante.

So, I have many questions:

Can I do that ?

What is the best way ?

Should I re-write all the R scripts or just the main script which call the
others will be enough?

QGIS will have access to spatia data only after the end of my algorithm, is
it a way to do it at any time ?

Cheers,

Sophie

[Qgis-user] Transformation tools plugin and CRS

[marquz74]

Hi to all,
I'm struggling with a *simple* issue concerning CRS transformations.
The native CRS of my layer is ED50 UTM 33N (EPSG 23033) and I need to get a
WGS84 (EPSG 4326 - not projected).
Some good fellows developed an NTV2 grid for the trasformation from ED50
(EPSG 4230 - not projected) to WGS84 (EPSG 4326) for Sicily.

So these these are the steps I followed:
1. EPSG 23033 -> EPSG 4230 conversion;
2. EPSG 4230 -> EPSG 4326 using the NTV2 grid by using the *transformation
tools* plugin;

After the transformation I expected the *final* CRS was EPSG 4326, but what
I got was a custom CRS:

USER:11 -  * Generated CRS (+proj=longlat +no_defs
+nadgrids=/mypath/myNTV2.gsb +ellps=intl +wktext).

So, if I export the shape and want to load it in another GIS, the associated
CRS results unkown.

I'm probably confused about some basic concept... where am I wrong?
Thanks in advance.
Marco
