[Qgis-user] warper for vector layers?

[Agustin Lobo]

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?

[Qgis-user] Modifying raster information?

[Agustin Lobo]

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?

If you use the "new" labelling engine (the buttons on the toolbar) the
labels should automatically be positioned so that they do not overlap.
You should not need to use data-defined label placement to achieve this.
Perhaps you were previously using the "old" labelling engine which is
available as a tab in the layer properties?  The old labelling engine
does not avoid label collisions.

QGIS opens CSV files read-only (well, there is a way to open them so
that you can add new entries, but not edit existing ones).

Re: [Qgis-user] warper for vector layers?

[G. Allegri]

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
it's not what you were looking for ;)

Re: [Qgis-user] warper for vector layers?

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.

No, but it seems there is a need to follow up with the organizing

and see what they say.

True, prompt seems to be a better default. It is changed now in master

Re: [Qgis-user] warper for vector layers?

[Agustin Lobo]

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.

Probably, you can view this custom railway-style (below) and modify to

Re: [Qgis-user] Double line Feature

[Nathan Woodrow]

You could just draw the line and then use the CADTools parallel tool to
create the second one.

I think the use case for drawing a double line would be limited.

[Qgis-user] Georeferncing Plugin issues (minus sign added to srcY and GCPs not removed)

[G. Allegri]

I'm doing some tests on the Georeferncing Plugin, and I wonder if the
following points are expected, my errors, or bugs

1) I'm testing it using a src raster in EPSG:3003 (projected CRS) and dst
raster in EPSG:23032 (projected CRS). When I insert a GCP, the srcY is saved
as a negative coordinate, i.e. the right value but with negative sign. This,
obviously, affects the georeferencing results.

2) When exiting the Plugin, it doesn't really get destroied but simply
hidden (opening it again doesn't creates a new instance, the plugin is shown
as we leave it), so that the GCPs on the main canvas are never
removed/hidden. If we want to keep the Plugin instance between hide/show
switches, I suppose that the canvas items should be managed the same way.

If someone can confirm these points, and they're bugs, I will open a ticket.

Thanks for the information! We have looked at the CADTools and the option
for drawing parallel, but just to "assign" parallel lines to existing line
objects. What we are basically looking for is tool to draw double lines in a
separate layer, but in a way of snapping some existing line in the centre of
double line.

Thanks,

[Qgis-user] Questions on CSV plugin & UTF8, or dbf to spatial.

[Koos Hagg]

Hi Everyone,

Is there a way to force the Delimited text plugin to read/process UTF8
encoded .csv's?

I am working with Vietnamese characters, which display fine encoded UTF8.
Working from an access database, I export my queries/tables/whatever and
save them as a csv, in UTF8 with OpenOffice. That works fine. If I then open
my csv with notepad++ or similar, the characters are preserved- great! But
when I bring the file in with the Delimited text plugin, the characters are
messed up. Why is this? how can I fix it?

Alternatively:
I can save the tables I want as dbf, which actually load nicely into QGIS as
a table, no problems with characters. My tables have Lat & Long columns.

How can I tell QGIS to draw points/create a spatial layer based on those 2
columns? Is there a plugin for that that I have missed?

Right now my work-around is to load both a csv and a dbf, and then join the
dbf to the csv points layer, and save as shapefile, deleting the fields that
are no good. It works but it is a little cumbersome.

Thanks!
Koos Hagg

I think you must read it "wrong" and then use Save As to change the

Re: [Qgis-user] Double line Feature

[Andreas Neumann]

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 line and add a tinner 
white or yellow line on top of each other. This way you symbolize line 
features and they appear as a double line. You can also create two lines 
and offset them from the center.


For snapping, the center of the line will be used.

In the cadtools toolbox you have a tool do draw parallel lines.

Re: [Qgis-user] Double line Feature

[Matej Mailing]

Basically we need this to define some sort of "protected area" (for example,
30 cm in both sides from the cable) along some telecommunication network
cables (mainly optical) and therefore I don't think only the representation
would be sufficient. Probably some plugin that would create polygon with a
centralized line that we are "snapping to" and with defined area (width)
would be even better than just two lines, because this way we could define
some color of fill of that closed "part" around cable in our projects for
example. Hopefully I explained it enough clearly, if you need more
information, please let me know :-)

Thanks,
Matej

Ah, is that what you want :-)

That's called a 'Buffer' in gis terms:

- load your cable layer in qgis
- go to Vector menu and in Geoprocessing tools, choose Buffer
- there you can choose for example 20 meter, this will create a 20 meter
buffer == polygon around your lines
- by creating a second buffer of say 50 meter, and giving that another
color, I think you will have what you want

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.

Hello!

That sounds like you need a buffer :-)
In QGIS, you find this functionality under Vector (fTools plugin) -> 
Geoprocessing (or similar, I have just the german version at hand at the 
moment...)

Re: [Qgis-user] Questions on CSV plugin & UTF8, or dbf to spatial.

[Koos Hagg]

Thanks for the idea. I thought of that but unfortunately it's not working

when I load the csv (ignoring the incorrect characters) and go to save as a
new csv in utf8, a dialog pops up saying:

> Save Error
> Export to vector file failed.
> Error: creation of data source failed (OGR error:)
>

i get this error in 1.7.1-2and the latest dev version
So that's no go. tried doing the same thing 'save as' but then a shapefile,
but that still has incorrect characters.

I did see the XY tools plugin by Richard Duivenvoorde, but I think it's the
wrong way around for this case, seems to me that it is designed for
digitizing from the canvas, to fill x,y columns, instead of take xy columns
and plot them...

[Qgis-user] urls / links as attribute values

[Richard Duivenvoorde]

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
browser (after loading the shape in qgis)... Not from the attribute
window, nor via the getinfo tool (these are long complex url's).

Ideally it would be nice to be able to just click on those url's and
then let them open the report in a browser.

Is this possible, or has anybody a clever idea how to to that?

We can offcourse alway build a plugin for that :-)

Richard Duivenvoorde

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.

Hi Koos,

if you have a dbf with the values in all columns, you could use the
XYtools plugin ... I think.
The XYtools actually has two functions: one is indeed to fill an X and Y
column of a csv or dbf file by clicking in a map.
But it also has an option to save that dbf file then as a shape file by
picking two columns as x and y column.

So please have a go: open your dbf in qgis, and then via 'Plugins/XY
tools/Save table as Point shape file' try to save it.
Not sure if it is utf-8 ready to be honest...

If you want, please sent me off list the dbf, then I can use that as a
test also :-)

Richard Duivenvoorde

Re: [Qgis-user] Questions on CSV plugin & UTF8, or dbf to spatial.

[Agustin Lobo]

I think you might be doing it right the second time (when you save as
shape in utf8 encoding), but perhaps you are still reading it
as non-UTF8 coding, hence you would see it wrong. When you open the
new shape file, do you select UTF8 as encoding?

Hi Richard,
Your plugin will be great! I tried it but did not get the right result, all
of the points get loaded in to a shapefile (the table is intact), but it
they are all placed at one or two x,y points...
I attached a dbf, you can give it a try. These are the center points of
communes in a particular province in Vn.

Agustin, thanks for your reply- yes, I always hav my layer import encoding
set for UTF-8. I have had day where I forgot it though and was scratching my
head until I figured it out!

Re: [Qgis-user] urls / links as attribute values

[Andreas Neumann]

yes - as Nathan pointed it out, you can do this with an Action. You can 
either hardwire a specific browser or write a small shell/batch script 
to open the URL.


It would be nice, however, to have a new data type in the fields 
parameters named "URL/URI" which would automatically open the browser, 
either inline (through webkit) or by opening the systems default 
webbrowser.

Me bad :-(

It's because I made the plugin for a case in our national reference
system which is in meters... so I cast every coordinate to an Integer...
which in this case put's all your points on either 105/21 or 104/21...

I will fix this this evening, and after an update of the plugin you will
have a good shape (I will sent you one off line also).

just set the action type to python and then use pyQT :)


The following python code should open the file pointed by %FIELD
with the default application (e.g. an image viewer):

from PyQt4.QtCore import QUrl; from PyQt4.QtGui import
QDesktopServices; QDesktopServices.openUrl( QUrl.fromLocalFile(%FIELD)
);


The next one will get an url instead, so if %FIELD contains
http://www.qgis.org it should open the web browser:

from PyQt4.QtCore import QUrl; from PyQt4.QtGui import
QDesktopServices; QDesktopServices.openUrl( QUrl(%FIELD) );


It's easy, isn't it? :)

Re: [Qgis-user] urls / links as attribute values

[Andreas Neumann]

yes - and this should also work for all OS - not just, Windows, Linux 
or OSX.


Thanks,

The following python code should open the file pointed by %FIELD

from PyQt4.QtCore import QUrl; from PyQt4.QtGui import
QDesktopServices; QDesktopServices.openUrl( 
QUrl.fromLocalFile(%FIELD)

The next one will get an url instead, so if %FIELD contains
http://www.qgis.org it should open the web browser:

from PyQt4.QtCore import QUrl; from PyQt4.QtGui import
QDesktopServices; QDesktopServices.openUrl( QUrl(%FIELD) );


It's easy, isn't it? :)

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

I found it not so easy to select/copy/paste the link and open it in 
a

browser (after loading the shape in qgis)... Not from the attribute
window, nor via the getinfo tool (these are long complex url's).

Ideally it would be nice to be able to just click on those url's 
and

then let them open the report in a browser.

Is this possible, or has anybody a clever idea how to to that?

We can offcourse alway build a plugin for that :-)

Re: [Qgis-user] urls / links as attribute values

[Richard Duivenvoorde]

Thanks all,

I was not very familiar with 'Actions', and it's really good working for
real data, and also for the WFS (which I actually have to use...)

I have to figure out what to do when I want to bring this data into a
WMS though  maybe instruct qgis to do featureinforequests with
format=text/plain and then fill a (attribute-like) table with it?

Anyway, thanks again,

Antw: Re: [Qgis-user] Questions on CSV plugin & UTF8, or dbf to spatial.

[Asmus Harder]

If you work from an MS-Access database, you can use the eVis-plugin to
draw the table as points. 
 
Have a look at
http://biodiversityinformatics.amnh.org/open_source/evis/documentation.php#d0e715

I don't know if this solve your problem with characters ...
But so you don't have to export your data to another file.

Hi Matej,

Sure it is possible.
You can use dissolve tool from Vector -> geoprosessing tools -> dissolve.
And in the dialog select dissolve all.

At least in the qgis 1.7.1 the dissolve tool is included in the buffer
tool. In the buffer dialog you can check a dissolve option to dissolve
all the buffers.

Hopefully this helps.

[Qgis-user] how to edit .gpx

[M . E . Dodd]

Can load a .gpx but can't seem to edit it, the editing button stays greyed out 
(qgis 1.7).  can save to .kml or shapefile and do edits but then loose some 
info from the original .gpx
looking at posts it seems that editing gpx has been in qgis for some time but i 
can't see how to do it.

As you can see the CRS is correctly defined, and the other metadata are

OTFR works fine, the raster is correctly reprojected on the 23032 reference.
No tfw or aux files in the same folder

It's making me crazy!

Re: [Qgis-user] warper for vector layers?

[Alex Mandel]

The closest thing I've seen in qgsAffine plugin which should let you 
stretch and rotate your layer to match a better base layer, though it's 
by hand/vision.


Enjoy,
Alex

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
it's not what you were looking for ;)

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?

Re: [Qgis-user] problems with georeferencing results

[Barend Köbben]

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 something...?

Yours,

Re: [Qgis-user] problems with georeferencing results

[G. Allegri]

Sure Baren, this was just an exercise ;)
I wanted to test regeoreferencing a raster and compare manual georeferencing
against reprojection.
I'm wondering if manually regeoreferencing an already georeferenced raster
can break things...

Re: [Qgis-user] problems with georeferencing results

[G. Allegri]

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 my
exercise. Even if reprojection wasn't enough, the best way would be to
remove any CRS reference from it.
Tomorrow I will do more tests, but I'm pretty sure that I was simply trying
a wrong procedure...

Re: [Qgis-user] problems with georeferencing results

[Ramon Andiñach]

I have no good reason to say this other than a niggling suspicion[1] but, yes I 
think it can.

-ramon.
[1] We occasionally have problems with the georeferencer, where it tries to 
rotate an image that shouldn't need to be. It's rare enough that I haven't been 
able to track it down properly, but this is on my suspect list.
