[Qgis-user] Cannot start NVIZ through SEXTANTE without vector layer

[Anita Graser]

Hi,

Is there a good reason why I cannot start NVIZ through SEXTANTE
toolbox without specifying a vector layer in addition to the raster
layers? What if I just want to see the height model?

Best wishes,
Anita

Re: [Qgis-user] Same layer extent?

Hola!

I am using GRASS inside QGIS and I need to perform some very basic
arithmetic on raster map layers using "r.mapcalc". Once I have created my
mapset in GRASS and imported all three rasters into GRASS from QGIS view, I
define my algorithm by simply doing "Raster_A + Raster_B + Raster_C".
However, the output gives the message "Unable to open raster map. Finished
with error".


The r.mapcalc model builder is, in my opinion, tricky to use. Can you 
try your mapcalc expression in the GRASS shell instead, and report back 
what result you get? i.e.


r.mapcalc ABC="Raster_A+Raster_B+RasterC"


I am not sure what the problema is, but I suspect that it may be related to
the extent of each layer, which is different for each raster:

Raster_A
Layer Extent (layer original source projection):
-264465.642805104122,3892490.3601970002055168:
1442088.185180295043,7588100.0655570002272725

Raster_B
Layer Extent (layer original source projection):
-231150.303056042897,3942814.959309562370:
1421853.422191778735,7568606.9837530003860593

Raster_C
Layer Extent (layer original source projection):
-302992.657880133924,3856086.4785620002076030:
1162350.090444798089,7559207.0393540002405643

Q1: What do these long numbers represent?


These are the upper left and lower right corners of each raster


Q2: Should every raster layer have the exact same layer extent for the
mathematical calculation to come out right?


No, you can use r.mapcalc on rasters with different extents. However you 
should be aware that wherever any of the maps is NULL, the result will 
be NULL. In other words, for each pixel, if either of your three maps 
has a NULL value, that pixel will become NULL also.
Note that there's also r.patch which was designed to combine maps which 
do not overlap, and fill in NULL values from one map with values from 
the others.



Thank you so much in advance!

Luciano

Anita

I guess you are using the latest stable version, not the github one.
NVIZ has been removed from SEXTANTE, since it does not really make
sense, as it is not an analysis process, and also because we had
problems like that and it was not very stable with the testing we did.

Sorry for the confusion.

Victor

Hi Victor,

Thanks for the fast response!
NVIZ could be the result of an analysis process though. I quite liked
being able to view data without the need to load it into GRASS first.
Too bad.

Best wishes,
Anita

Anita

Thanks for the feedback

Let me check later if I can improve on the way it is called, so you do
not have problems with missing vector layers and similar things. I
also found that sometimes layers where not shown, so all that together
made me decide to remove it. And I thought no one was going to miss
it...but it is good to have your feedback, and you are right in that
it would be nice to be able to open and view data after an analysis.

Let me check it and I might put it back, so you can test it and
eventually help us have a working thing that we can keep in SEXTANTE.

Thanks again!

Like Anita, I also enjoyed having nviz on Sextante, but its certainly not
something that I consider very important as an end user.

Hi Andrea,

There is not print functionality.

The only two options are:

* Screenshot
* Copy/Paste into other application

Would you need this feature a lot? If yes, consider making a feature 
request.

[Qgis-user] load data in Qgis by a query on geom column

[Pietro Rossin]

Is it possible to load data in qgis from postgis by a query on the geometry
column?

If for example I'll like to load data between Xmin adn Xmax in pgadmin I'll
do like this:

SELECT* FROM public.mytable WHERE st_xmin(the_geom) >= myXmin and
st_xmax(the_geom)<= myXmax;

How can I do it in qgis? (if possible..)


Are these query feasable in qgis?

SELECT ogc_fid, st_transform(st_makepolygon(mytable.the_geom),
3004)::geometry(PolygonZ,3004) AS the_geom, mytable.layer
   FROM mytable
  WHERE st_isclosed(mytable.the_geom) = true;

Re: [Qgis-user] Sextante tools via Qgis : information regards Watershed analysis

[laurent celati]

Hello,

Thanks for your reply. As you know yesterday i tested Grass via QgisFORQgis.
There was a bog during the process and i had a error message. 

This morning i have tested Grass via Qgis and it's works well. I have 


1/With Grass r.watershed i have to enter this following parameter : "minimum
size of exterior watershed basin" (without unit value). What criteria
determines the value to be enter? How to know this value ? 

In my case, i 'm using SRTM 90m as DEM raster input. 


2/According to you, what is the better tool for between r.watershed or
Taudem "StreamReach and watershed" ?

Thank you in advance.

Hi Tyler,

You need to install pyspatialite.

Find out first the version of your spatialtite and follow the
instruction on how to install pyspatilate here.

Hi,

are there perhaps two or more gdal dlls on your system? Can you check 
on your complete C drive and see if there are more dlls around for gdal? 
Sometimes this is the cause of such problems.

Re: [Qgis-user] load data in Qgis by a query on geom column

[haubourg]

If you just use WHERE clauses, you can use query builder directly. 

You can also add queries generating geometries on the fly without creating a
view in Postgis using FASTSQLLayer plugin (it needs an unique id in query)

[Qgis-user] Problems with WMS Visualisation

[Michael Werner Maur]

Hello,

we provide many WMS. These WMS are supported by UMN Mapserver. In some of the 
concerning MAP-Files the Header-Marker 'EXTENT' has an smaller expansion than 
the 'EXTENT' of an individual layer of that WMS.

The result is, that the given picture in QGis is cut to the size of the 
Header's extent. 

Is this really the correct interpretation of the WMS standard ? There are 
other GIS systems, that do not interpretate the standard in that way !

Here the URL of the WMS to test it :

http://www.geoportal.rlp.de/mapbender/php/mod_showMetadata.php/../wms.php?layer_id=36465&PHPSESSID=847f2d5bfce485e9a7dcd93c74ce55b1&REQUEST=GetCapabilities&VERSION=1.1.1&SERVICE=WMS

Re: [Qgis-user] load data in Qgis by a query on geom column

[Pietro Rossin]

@Wolf-E. Altmann
db-manager don't work for me

for example, if I perform a query like:

SELECT ghiaioni.ogc_fid, st_transform(ghiaioni.the_geom,

that will return all feature between xmin and xmax db-manager make me see
the results (sql window) like a table, but if I select to load as a new
layer with correct geom and id fields nothing happens and the message log
window in qgis report an error like:

What is that??

@haubourg

FASTSQLLayer plugin works great!
But It's in user-contributed plugin repo, not official, right?

what do you mean with

Which query builder? the one that is on the add postgis vector data? With
that I can only select item from a table, not execute query on geometry
column, right?

Thankyou all

Re: [Qgis-user] SQLite plugin

[William Kyngesburye]

Looks like a different error now, and one that might really be related to 
something wrong with pyspatialite.

If you installed QGIS/GDAL a while ago, you should update.  I did have a 
problem in the SQLite framework at one point where it wouldn't load the 
spatialite stuff.  Fixed in the latest frameworks.

[Qgis-user] Simulation of dam failure & mapping of flood risk downstream

[laurent celati]

Good afternoon,

I have to simulate an artificial dam failure & mapping of flood risk
downstream. I have already generate watershed file thanks to r.watershed.

Now i want to mapping and calculate flood risk downstream (water level /
volume /cubature) from a few available informations like charge,flow,etc.

Could you throw light for me please? If you know other tools and algorithms
that can help me in my study, don't hesitate.

Thank you in advance.

With kind regards.

The standard says nothing (AFAICT) about a situation when the extent
reported in GetCapabilities is wrong (differ from layer extent). It is
simply server side problem IMO.

Definitely we are not going to support such a case because that would
mean to always request full current extent even if we are outside
(according to GetCapabilities) the layer extent.

Re: [Qgis-user] SQLite plugin

Hi William, I notice the pyspatialite link Noli provided points the source back 
to your website for Mac OSX users.  If I did a complete uninstall/reinstall of 
QGIS and the GDAL framework shouldn't that fix the problem with pyspatialite?  
Thanks, Ty

If you installed QGIS/GDAL a while ago, you should update.  I did have a

Re: [Qgis-user] SQLite plugin

[Frazier, Tyler James]

When I try to load a QGIS layer into the SQLite Database I get the following 
two errors

The SQL query seems to be invalid.  no such table: geometry_columns

This DataBase seems to be a valid SQLite DataBase but not a valid SpatiaLite One
Would you like QSpatiaLite to automatically transform it to SpatiaLite 
(information won't be lost) ?

If I say no to the transform, the import seems to work, but the tables don't 
appear in the plugin, just in the database manager (where I can see the records 
are correct).  If I say yes to the transform the tables appear, but they are 
empty.

Any ideas?  Maybe I should follow Nilo's suggestion regarding pyspatialite and 
the instructions at 
http://www.gaia-gis.it/spatialite-3.0.0-BETA/spatialite-cookbook/html/python.html
  ???

Depending on your OS, you'll probably have to install gdal-ecw and copy
the ecw dll (that you must acquire, or have on your system) in the osgeo
directory. Search the net for detailed updated instructions.

I think the best is to ask them to distribute it (they are using QGIS,
so they have already solved this). It would be nice to ask them to put
these instructions on their public website.
However, I think tehy also distribute data and services in "normal" CRS.
All the best.

[Qgis-user] How to have a better QGIS: let's manage targeted donations

[Paolo Cavallini]

Hi all.
For the smooth and fast release of 2.0 to happen, we need some help from users.
We decided to fix at least:
- new symbology, replacing the old one
- new labelling, replacing the old one
- sextante
- new web site
- manuals completed in the new infrastructure.
Moreover, it is likely that we'll need some work to fix plugins, broken because 
of API changes.
We agreed in starting to handle targeted donations, with one of the several 
systems available (e.g. PledgeBank etc.; I've also seen the system recently 
introduced by Ubuntu [0]; nice but too invasive for my taste).
I do not have experience in any of those, so I would ask all of you to share 
your knowledge, experience, and preferences.
Also, I would greatly appreciate if someone would step in and help in the 
management of the system.
In the meantime, I would ask developers to check if they have time do complete 
one of more of the task, and estimate the necessary resources.
If we can tap on this, I am pretty sure our development cycle will improve, 
with benefits for all users, so please come and help.
All the best.
