[Qgis-user] extend problem with openlayers in composer
Hi all, tested with qgis1.6 on both ubuntu10.10 and windowsXP, the extend of a openlayers layer (using openstreetmap rendering) in the composer is zoomed in when the canvas is exported to an image (png, jpg,...) or to a pdf file.

Re: [Qgis-user] How to Identify the best subdataset of a dataset of points which follow a canonical distribution ?
Hello, in first approch you can compute the general mean of your observations and select only stations with rain mesureaments failing inside a determinated tolerance around that mean. Another common use would be to randomly remove some stations and look at the resulting variance against the general variance (with all stations) and stop when a tolerance is reached. The best approach would be to play with kriging your observations and look at the resulting map when some stations are removed.

Re: [Qgis-user] How to Identify the best subdataset of a dataset of points which follow a canonical distribution ?
Sorry for the mistake, I didn't read carrefully. Without observations, it will be hard to extract some relevant informations on just geographical situations (distances matrix?), unless you can work with others datas (wind speeds and directions, ...) and correlate them with rainfalls. 2011/1/25 Anita Graser anitagra...@gmx.at: Hi Lionel, Those are good approaches. I think the problem is that Nikos doesn't have any measurement data yet (because he has to pay for every single station). So in this case, I don't think these methods can be used.

Re: [Qgis-user] Re: Overview (inset map ) in map composer
Hi Andreas, I don't like manually setting extents values in the composer, I prefer having the same extents in the map canvas and in the composer, but sometimes I can't because the composer doesn't exactly follows the map canvas (specially when I want to print in A3 format). I know we can zoom with the mouse wheel but then the zoom factor is sometimes too big. Maybe if we can have more precision on the zoom factor, like by holding the CTRL key while zooming with the mouse wheel, or/and a zoom-rectangle button... 2010/10/28 Andreas Neumann a.neum...@carto.net: Hi Lionel, Do you mean a zoom-rectangle in the selected map view? I usually set the map scale to some round value (I don't like map scales that are not rounded). This sets the zoom value for me. Then you can change the map extent by dragging the map content. Are you aware that you can also zoom with the mouse wheel in the map in the print composer? Given this functionality - do you still think that the zoom rectangle is necessary?

[Qgis-user] postgis layer from a view
Hi all,
I can't load datas from a postgis view, the loader complains about no
uniques values and int4 type, however the view starts with SELECT
nextval('my_seq'::regclass)::integer AS gid, com.the_geom, ... (the
gid column is not listed in the error message) which works perfectly
if datas are stored in a table. Is there a trick to load datas from
views, and more generally is it possible to force the postgis provider
to create an internal unique key?

nrj.ecs, nrj.cui, nrj.spe, nrj.total, com.the_geom
FROM residentiel.nrj_sourcesfixes nrj
JOIN spatial.commune com ON nrj.commune::text = com.code_insee::text;
the residentiel.nrj_sourcesfixes is another view.
2010/6/1 Bernhard Ströbl bernhard.stro...@jena.de:
Dear Lionel,
AFAIK the view must contain a field being defined as primary key in the
underlying table, moreover this field must be of type integer.
The view must be defined in a way that every element (thus every primary-key
value) is unique. In case the view contains a join resulting in several
primary-key fields you can choose which one QGIS should use.
So your view definition lacks the primary-key field, although the sequence -
of course - populates gid with unique values.
Maybe you could post the complete view definition (and the table
definitions, too) and we could see if we could help you in creating a
working view.

Hi all,
I can't load datas from a postgis view, the loader complains about no
uniques values and int4 type, however the view starts with SELECT
nextval('my_seq'::regclass)::integer AS gid, com.the_geom, ... (the
gid column is not listed in the error message) which works perfectly
if datas are stored in a table. Is there a trick to load datas from
views, and more generally is it possible to force the postgis provider
to create an internal unique key?

If I recall correctly postgis manager assumes a PostGIS-Installation on the same machine and thus expects the presence of the loader (shp2pgsql).

Hi, we all wait for the new symbology system :) If you want, I have qgis-styles files for Corin Land Cover level 1, 2 and 3, but in french... Cheers no-reply a écrit : Hello, just wandering if is there a way to apply to vector classes predefined colour classes, like Corine land cover colours or altitude levels or even a grayscale.

[Qgis-user] Problem with the join attributes by location ftools plugin
Hi all, hi Carson, Needing to sum some pollutants concentrations stored in a polygon shapefile, I come across a big problem with the join attributes by location of the ftools plugin. My source polygon shapefile is for simplification a regular grid, and the target shapefile too, with exactly the same limits (in fact the source shp is based on the target on). When calling the plugin, it first complains about source and target are in differents CRS, which is false (I use EPSG 27572), and after computation using the sum summary of interesting features, the results are somewhat unexpected, because in each target polygon, the sum represents the sum of the contigous sources polygons, and not just the sources polygons INSIDE the target one. To be clear you can see in the attached file an example where the sources concentrations values are in normal font (one value by polygon), and in bold the resulting sum in the targets polygons (where normally expecting the same values as in the sources). I think there's missing a test in the plugin to select values if they are strictly inside the target. Hope there's a simple solution, I really need the values :/ Thanks PS : without this problem, the ftools plugin is really a nice tool.

Re: [Qgis-user] QgsVectorFileWriter
Hi Carson,
Le mercredi 21 janvier 2009 à 16:48 +, Carson Farmer a écrit :
In this way, it would be better to save in a temporary shapefile first,
and if the process finishes successfully, remove the destination
shapefile and copy the temporary shp to the new location.
hmm, I don't know about this...
Firstly, it's only useful to do this if you're concerned about the
initial file, but since you appear to be writing to a tmp directory,
this probably isn't all that critical...
Sometimes I don't want to get 2 versions of a shp and select the source
shp to be overwritten. If something goes wrong and the source is deleted
first, all is lost...
Secondly, this creates the possibility that if something goes wrong, you
have TWO useless files lying about on your system (one you were trying
to replace, and the other that didn't finish writing properly).
A simple test where if a problem occurs, we delete the tmp file...
The better implementation would probably be to use the memory provider
to create a temporary QgsVectorLayer in memory, and if the process
finishes successfully, remove the old version and write the memory layer
to file. Of course, this only works if you're working with relatively
'small' layers, if you have huge vector layers ( 500,000 features) then
you're probably better off just writing directly to file...
mem_layer = QgsVectorLayer('Point', 'layer_name', 'memory')
you'll have to double check the above, this is just from 'memory' ;-)
It may be a solution :-)

Re: [Qgis-user] Enhancement Requests: Enhanced Map Tips
If this enhancement could be added to the labels too (with always a good labels placement...), it would be perfect :-) Le jeudi 06 novembre 2008 à 19:34 +0100, Agustin Lobo a écrit : I comment on the one on Enhanced Map Tips. I actually would add the ability of drawing a simple plot, for example to display reflectance values across bands or time series of vegetation index a la Envi. Not sure if this should be a different ticket. BTW, priority minor: annoyance or enhancement should not be split in two different categories? I mean that an enhancement could not be of minor priority, and certainly not similar to a minor annoyance.

I assigned the latter to Marco Hugentobler, since he is working on the print composer.

Hi Paolo, thanks for the link, effectively some entries in the report page are in our whishlist, specially ticket 54, 361 and 1063.

[Qgis-user] Select Features bug
Hi all, when using the Select Features tool on a polygon shapefile and holding down the Ctrl key for selecting some features by hand, we can select 6-7 polygons, but after the entire dataset is selected!

[Qgis-user] GRASS tools window
Hi all, can't login on the forum, then I post this request here. I think it would be great if we can have another tab on the GRASS tool window where we can put favorites/frequently used GRASS tools, because searching for a particular one make sometimes confusing. Plus moving the Browser tab at the first position to avoid clicking on the modules tab each time we have to close a tool tab (and set the name of the tool on the tab), and the GRASS window will be perfect :-) My 2c -- Lionel Roubeyrie - [EMAIL PROTECTED] Chargé d'études et de maintenance LIMAIR - la Surveillance de l'Air en Limousin http://www.limair.asso.fr ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
Re: [Qgis-user] one raster from tiles
Big thanks Yves for pointing gdal (never thinking at all for it), there's a special command to merge multiple tiles into one with gdal_merge.py. Keep gdaltindex under the pillow :-) Le lundi 21 avril 2008, Jacolin Yves a écrit : Le Monday 21 April 2008 14:04:39 Lionel Roubeyrie, vous avez écrit : Hi all, I have several tiles rasters (geotiff) describing a large area in high resolution, and generally I work on a small area, having to import all tiles because they don't have explicit names (and without the possibility to put them directly under a group (see a previous post), which should be a great improvement). Then, is it possible to extract/create a new raster for the desired area with QGIS/GRASS (know it's possible with Arcmap, with difficulties) ? Thanks Hi Lionel, You can use gdaltindex to create an indexof your tile in shapefile format, after displaying it you can show the location field on your map and find the filename of the Raster you have to load for your area. If you want to extract an area from your raster you can again use gdal [1] with some option to cut all data out of your area. I think you can use g.region to zoom into your area and then export the raster from your view region, after creating one main raster. I am agreeing with you for a better group management ;) May I need to create a new ticket? Another possibility should be that QGIS manage index file.
