Hi!
We have a vector layer that has been digitized over a raster with
wrong settings (wrong pixel resolution).
Is there any way to correct the geometry of the vector layer by
defining control points with the new coordinates and apply
a warping in qgis?

Hi!
We have a raster layer with wrong settings (in particular, wrong pixel
size). Is it possible
to edit these values? We have changed the resolution in R and it would
be possible
with grass also, but could this be done in qgis directly?

I don't think Qgis has vector warping tools. The Georeferencer plugin
manages only raster data, and for its polynomial transformations based on
GCPs use GDAL directly, which itself implements warping for rasters only.
I think that writing a warping plugin for vectors woudn't be too hard, but

Hi Agustin,
if I understood well, you would need the Affine transformation plugin,
anyway, the current implementation ask you to include the transformation
parameters, so you need to do some calculations on your own before.

Hi all,
Does the current raster georeferencer output the parameters used for
the warping? A fast solution would getting
trying on a raster layer first and then using the affine
transformation plugin with the same parameters.

Hi all,
It would be very useful to have a feature to draw a Double line in QGIS. Is
this currently possible?
Thanks.

Probably, you can view this custom railway-style (below) and modify to
draw double line instead, if applicable.

If I understand you correctly, you just want to symbolize an existing
LINESTRING feature with double lines. You don't want to add additional
parallel features, correct?
If you look at the new symbology engine, you can stack multiple lines
upon each other. F.e. you can create a thick black

I also think that buffer is what you really need to use.
In order to snap to the original line just keep it in the project too.

Hi List,
we have a webservice which returns a shapefile with attributes.
one of the attribute values is a full url to some real time generated
report for every feature in the shape (one report for every feature).
I found it not so easy to select/copy/paste the link and open it in a

Sure. You can use layer Actions for that. Here[1] is a example of opening
a photo using a layer Action, I'm pretty sure the same process can be done
with urls.

I think you might be doing it right the second time (when you save as

yes - as Nathan pointed it out, you can do this with an Action. You can

It would be nice, however, to have a new data type in the fields

Hi Giovanni,
I don't understand: you want to change a projected raster (in CRS 3003) to
another projection (23023), so why do you need the georeferencing plugin?
The data is already referenced, so it sounds to me you just want to
re-project it, using the Raster Warp menu.
Or am I missing
Thanks to all of you!
This is it - all current issues solved! :-)

Sure Baren, this was just an exercise ;)
I wanted to test regeoreferencing a raster and compare manual georeferencing

I'm wondering if manually regeoreferencing an already georeferenced raster

Ok, i got it.
The reason it doesn't work is probably easily explained: the source X/Y are
considered as raster space coordinates, while I thought that having the
raster a CRS assigned this was kept into account during the warping.
Probably manual re-georeferencing is conceptually unuseful, outside
I have no good reason to say this other than a niggling suspicion[1] but, yes I

able to track it down properly, but
