Hello,
I would like to batch-write some raster files from a project to one common
folder using a script. This is my function:
def writeRaster(rasterObj, pathToFile, cols, rows, rasterExtentObj,
rasterCRSObj):
provider = myRaster.dataProvider()
pipe = QgsRasterPipe()
I Larissa,
it's Postgresql complaining that no user name is provided for the request. Do
you have a valid connection initialised befor between QGis and PostGIS?

Hi!
It took me a (looong) while to call an external script from a QGIS plugin on my
Windows machine at work. I'm not sure if this was a problem with the two Python
interpreters - from QGIS and from ArcGIS or what so ever... It worked with no
issues on my linux machine.

Hi Joris,
I'm not quite sure if this will work with wms-layers too. But I applied a
plugin called 'point sampling tool' (I guess thats the name) to sample raster
values at point locations. If you want a text based file, this would be a
possible way:

Btw, for what purpose photo2shape is a required package here?
Isn't exifread supposed to

You can even manipulate page format/sizes in the serial print, if this is what
you want.
Good luck,

Hi,
is there a more easy way to export a map composition to an image file? I see,
that I can limit the map by changing the vertical/horizontal page extent. But
if I want to prepare many simple map overviews of different sizes and aspect
ratios for a report, I'd prefer to have a dialog saying -
are not updated by QGIS
and therefore the change became not visible back in ArcGIS. Hope it helps,

Does anyone knows a workaround that keeps feature properties of a dxf-file?
Specifically, I have isolines with a property elevation that is to keep for

I wonder, where I could find a working point sampling tool for QGis 2.6. The

Hello everybody, i have a problem with SQL, i need a function in QGIS similar
to MOD in ArcGIS.
In ArcGIS i use MOD here:
MOD ( field, 10)=0
The result are the multiples of 10.

Hi,
I've loaded a big set of contour lines with 5 m stepping from an ArcGIS File
Geodatabase. From time to time I need to modulo out the 5 m lines in the viewer
(showing only 10 m steps). Given a column contour this should work (shouldn't
it?):
contour % 10 = 0
However, it returns 0 lines
Hi,
Since I work with QGIS the dissolve function tends to be very slow for me.
E.g., it takes ours to dissolve a layer of 15000 polygons. ArcGIS in contrast,
does the job in a couple of minutes. Usually, it doesn't take too long in our
house until one of our ArcGIS licences is freed to solve

Hi Torsten
That sentence is right, both for filter or for ruled based styling. Perhaps
contour is a text column...

Hi!
I'm novice to use free DEM data. I work on a medium (~60km) scale area in
Germany. It's basically about geology. As don't need accurate DEM data for the
time being I read through google that gtopo30 or (even better ?) DTED data
from German Aerospace Center may be utilized, which are all
, but also for map tips and perhaps symbolization.
Until then you have to do it yourself.
