[QGIS-Developer] Problems with adopting scaled representation from QGIS

[Otto Dassau]

Dear Developers,

i would like to describe a problem using QGIS WMS with defined scale visibility 
for layers. We already spent quite some time on it and for us it seems to be a 
wrong scale calculation in QGIS. But since we are not sure we would like to 
ask, if someone, deeper in the code, can have a look and, if it is the case, 
can provide a (payed) fix.

To better describe the problem we provide a sample web project under 
https://gws-dev.gbd-consult.de/project/scales_qgis/@753753,6661615,10

The "Bank" layer has a scale-dependent representation defined in QGIS between 
10 - 8, but is not rendered by QGIS at the scale 10.

QGIS server is called with these parameters:

http://localhost:4000?
layers=Bank%2010-8
=%2Fdata%2Fshared%2Fpoi_scaled.qgs
=True
=748163.2561805135,6646683.920240255,767707.2561805135,6679247.920240255
=698
=1163
=EPSG%3A3857
=image%2Fpng
=GetMap
=1.1.1
=WMS
=

The resolution (meter per pixel) results from bbox and width

(767707.2561805135 - 748163.2561805135) / 698 = 28

According to OGC specifications, 1px = 0.28 mm x 0.28 mm, i.e. the scale here 
must be exactly 10. But QGIS calculates it differently (excerpt from the 
debug log): 

src/core/geometry/qgsrectangle.cpp:152 : (toString) [0ms] Extents : 
748163.2561805135337636,6646683.9202402550727129 : 
767707.2561805135337636,6679247.9202402550727129
src/core/qgsmapsettings.cpp:222 : (updateDerived) [0ms] 
748163.2561805135337636,6646683.9202402550727129 : 
767707.2561805135337636,6679247.9202402550727129
src/core/qgsmapsettings.cpp:223 : (updateDerived) [1ms] Adjusted map units per 
pixel (x,y) : 28, 28
src/core/qgsmapsettings.cpp:224 : (updateDerived) [0ms] Recalced pixmap 
dimensions (x,y) : 698, 1163
src/core/qgsmapsettings.cpp:225 : (updateDerived) [0ms] Scale (assuming meters 
as map units) = 1:100314.9605275292903

The scale (with the same bbox / width) is calculated as "1: 100314", and 
because that is greater than 100,000, the layer is not rendered by QGIS. 

We assume that there is a rounding error somewhere. As said we would be happy 
if a QGIS dev could have a look. The project file and data are in 
https://gitlab.gbd-consult.de/gws/gws-dev/tree/master/data/shared 
(poi_scaled.qgs and poi / subfolder).

Thanks a lot!
Otto

[QGIS-Developer] is_layer_active expression

[Otto Dassau]

Dear Devs,

in QGIS 3 I found the expression "is_layer_active" within the copyright
decoration very useful. I would like to use this expression also within the
print composer, but it seems to be not available there.

Is this correct, are expressions not available all over QGIS within the
expression builder? And how can I get this expression working for the print
composer as well? 

Thanks for any hint.

Hi,

after a second try, it seems that QGIS server version 3 supports expression
variables within the rule based renderer - sorry for the noise.

Thanks,

[QGIS-Developer] expression variable for rendering with QGIS server

[Otto Dassau]

Dear developers,

I use expression variables within the rule based renderer. For example:

CASE WHEN @project_title LIKE '%adult' THEN "fclass" = 'school' ELSE
"fclass" = 'kindergarten' END

This works in QGIS desktop but not with QGIS Server Version 2 and 3. Does
QGIS server not support this feature at all? Or do I miss something?

Thanks for any hint

[QGIS-Developer] lizmap configuration disappeared

[Otto Dassau]

Hi,

login as admin to lizmap client (3.0.4) I cannot see the menu entry "my
account" anymore to configure the client. I only can click on "exit". I must
have set some wrong hooks somewhere during another session :( and after that
the menu disapeared. 

Can I change some values in a config file to be able to see the Lizmap
configuration as admin again?

Hope the qgis lists is the right place for such questions. I haven't found a
lizmap ml.

thanks a lot

[Qgis-developer] qgis server / xvfb on ubuntu xenial

[Otto Dassau]

Hi,

I have a problem using xvfb with qgis server on ubuntu xenial: 

* QGIS server 2.16 on trusty with xvfb 2:1.15.1 works well as described by
  Alessandro: http://www.itopen.it/qgis-server-setup-notes/ . We use it to
  render HTML in GetPrint.

* QGIS server 2.16 on xenial with xvfb 2:1.18.3 doesn't work. It doesn't
  crash but the HTML part stays empty. It seems that the xenial xvfb
  package doesn't work together with current qgis server.

Do others have similar experiences?

Otto

[Qgis-developer] Change PSC Community Manager Role

[Otto Dassau]

Dear Community,

there will be a change in the QGIS PSC. 

I (Otto) decided to step back from my PSC role as Community Advisor. I
enjoyed being part of the PSC for a couple of years but realized that I
won't find enough time in the future for this job anymore.

At the hackfest in Bonn the PSC decided not to recast the Community Advisor
role. Instead there will be team managers who together with a team of
contributors will take care about the tasks this role has included so far.

In this context we are happy to announce that we have already found two well
known community members to fill this gap - Lene Fischer from Denmark and Yves
Jacoline from France. Lene will concentrate on community tasks and Yves on
documentation.  

More details about the new structure will be announced by the PSC in the
near future.

Best wishes
Otto

Re: [Qgis-developer] * Important* Preparations for QGIS Developer Meeting in Bonn

[Otto Dassau]

Hi,

here are some news for people who are still looking for accomodation in
Bonn. We called some hotels and this is the result: 

2 have still enough space for the 10-15 people that are probably still
looking for rooms.:

1) IBIS Hotel (5km from Basecamp), but with good connection by public
  transport http://www.ibis.com/gb/hotel-1441-ibis-bonn/index.shtml
 
  Costs for Single and Double are the same (128€) for 2 nights from 21.-23.
  August. 

2) Hotel Garni Jacobs (15 min walk)  http://www.hotel-jacobs-garni.de/

  Enough rooms for 10-15 people. Costs are 65EUR/75EUR for Weekend/Week in a
  single room and 90EUR/100EUR for Weekend/Week in a double.

Since we have no idea how long you want to stay and what you prefer, we
would kindly ask you to make a reservation personally. And if you need help,
we can assist, of course. Just send me an email.

Regards,
Otto

Hi,

we are now about 30 people on the wiki lists for the hackfest in Bonn and we

https://wiki.osgeo.org/wiki/FOSS4G_2016_Code_Sprint#Registered_Attendees
https://github.com/qgis/QGIS/wiki/QGIS-Hackfest---Bonn---August-2016

but I have heard, that there are still people missing on the wiki list and
there are also still (about 10-15) people looking for accomodation. Please
add your names (also important for us to organize the dinner).

We are in contact with places close to the basecamp. If you need help,
please send an email directly to me, so I can organize something for you.

Hi,

we started to prepare our own QGIS wiki page to organize the upcoming
hackfest in Bonn and to make sure that our hackfest will be fun. Many of you
already registered at foss4g wiki page at

https://wiki.osgeo.org/wiki/FOSS4G_2016_Code_Sprint#Registered_Attendees

and I tried already to put it in sync this with our new internal page at

https://github.com/qgis/QGIS/wiki/QGIS-Hackfest---Bonn---August-2016

But I need your help and would like to ask you to do the following for us:

a) If you want to participate, please register twice in the FOSS4G Wiki and
in the QGIS Wiki. This is important to have a smooth organisation on QGIS
and FOSS4G side.

b) If you already registered at one of the pages, please check again and make
sure you appear in both lists.

To organize further accomodation and our well-known dinner, we need your
information as quick and as complete as possible.

Thanks a lot

I also thought that money is most important. But it seems to be only a
(minor) factor. Giving people recognition seems to be very important, too.
I agree with Paolo and maybe we can improve that.

Another thing I thought about is, if writing the official documentation in
QGIS is still too complicated? We tried to make it as simple as possible,
but I am not sure, if it is easy enough. Maybe not explained good enough?

Otto

[Qgis-developer] Call for applications: QGIS Manual Update and Improvement

[Otto Dassau]

Dear QGIS community,

In the last few years we have been steadily improving the amount of funding
we are able to accumulate in the QGIS project. Our goal in obtaining funding
is always to 'make QGIS better'. Up until now we have focussed funding on
high profile aspects of the project: Funding regular hackfests, paying for
bug fixing work prior to releases, funding infrastructure such as servers,
domain name registrations etc. 

With improved funding levels we now have the opportunity to also start
addressing some of the many less obvious components of QGIS that badly need
attention, but often don't attract volunteers. In our PSC meetings it was
agreed that we would start this initiative by funding one or more
experienced users to improve the QGIS manual. Here, briefly, is the vision:

As an experienced QGIS user you currently have two main resources: The QGIS
manual and the QGIS training manual. In this call we focus on the manual,
which is already an excellent resource on available functionality in QGIS.
The challenge is to keep it synchronised with all new features, and examples
and figures often run the risk of being out of date. This is the case
already for several chapters of the manual for the latest QGIS releases and
we want to start optimizing this.

We would love to see the QGIS manual providing a readable narrative
explaining the purpose (with images and illustrations if needed) of each
feature. It can also provide short sample snippet where useful, which in
many cases you can simply cut and paste into your code and then tweak to get
started.

For this funded effort we are thus seeking one or more individuals to lay
the foundation for this work:

* verify and improve the norms and guidelines of the documentation and
  especially its update process together with the PSC.
* update the manual to include all features that are available within the
  latest QGIS release (2.12).
* update figures, if necessary according to the defined guidelines (size,
  desktop-environment, resolution,...).
* populate the manual with further short examples and improved descriptions,
  without competing with the training manual.
* do these in a nice clear and concise writing style, taking inspiration
  from other software manuals, if available.

If you think this is something you are able to do, please contact the QGIS
PSC using this form and let us know!

http://goo.gl/forms/18vTEOg7Be

Best wishes,
Otto

[Qgis-developer] QGIS CRS handling question

[Otto Dassau]

Hi,

I would like to understand QGIS behavior a little better for CRS handling. 

I have a tif/tfw file (input.tif) and would like to create compressed geotiff
tiles from it (output.tif).

1) When I use

gdal_translate -co COMPRESS=JPEG -co PHOTOMETRIC=YCBCR -co TILED=YES \
 -a_srs EPSG:25833 input.tif output.tif

gdalinfo shows:

Driver: GTiff/GeoTIFF
Files: output.tif
Size is 16100, 15300
Coordinate System is:
LOCAL_CS[ETRS89 / UTM zone 33N,
GEOGCS[ETRS89,
DATUM[unknown,
SPHEROID[unretrievable - using WGS84,6378137,298.257223563],
TOWGS84[0,0,0,0,0,0,0]],
PRIMEM[Greenwich,0],
UNIT[degree,0.0174532925199433]],
AUTHORITY[EPSG,25833],
UNIT[metre,1]]
[...]

loading this file in QGIS I am asked to provide the CRS for the layer,
although it should be written in the GeoTiff header. 

2) When I use 

gdal_translate -co COMPRESS=JPEG -co PHOTOMETRIC=YCBCR -co TILED=YES \
 -a_srs +proj=utm +zone=33 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m \
 +no_defs input.tif output.tif

gdalinfo shows:

Driver: GTiff/GeoTIFF
Files: output.tif
Size is 16100, 15300
Coordinate System is:
PROJCS[UTM Zone 33, Northern Hemisphere,
GEOGCS[GRS 1980(IUGG, 1980),
DATUM[unknown,
SPHEROID[GRS80,6378137,298.257222101],
TOWGS84[0,0,0,0,0,0,0]],
PRIMEM[Greenwich,0],
UNIT[degree,0.0174532925199433]],
PROJECTION[Transverse_Mercator],
PARAMETER[latitude_of_origin,0],
PARAMETER[central_meridian,15],
PARAMETER[scale_factor,0.9996],
PARAMETER[false_easting,50],
PARAMETER[false_northing,0],
UNIT[metre,1,
AUTHORITY[EPSG,9001]]]


loading this file in QGIS, I am *not* asked to provide the CRS for the
layer, but QGIS assigns the wrong CRS. In my case I want EPSG 25833 but get
EPSG 3006 (which has the same parameters as 25833, but is not what I want).

How can I make QGIS read the CRS correctly? Does anybody has a solution for
this?

Thanks a lot

 Something like:

 public role is a specific role which contains all user.

[Qgis-developer] QGIS hackfest Linuxhotel News

Hi,

I have some not so good news for all who arrive on wednesday and before
thursday late afternoon. I was just informed by the linuxhotel, that
they will have another big event on thursday, 2nd october. They have given
priority to this event, because that's what they make money with (we only
pay a very reduced price).

For us it means, we only have one smaller room (maybe for 15 people)
available on thursday until maybe 7pm and all others have to split up to
several other rooms in the linuxhotel.

We will find a solution anyway, there is internet everywhere, but I wanted
to inform you, so you are not disappointed, if we are not able to work all
together in one room until thursday evening.

Whish you all a save journey to Essen!

 Hi All,
 
 It is hard to figure out where in the conversation to interject but 
 Victors counter-suggestion appears appropriate to me.
 
 Being involved in several open source projects, creating tutorials for 
 these and having in the past been involved with trying to contribute to 
 the main documentation for these packages it is obvious to me that 
 developers need to be involved in documentation.
 
 Users rarely are able to decipher code and trying to figure out when and 
 how to use a particular feature can be quite daunting even for the most 
 experienced person.
 
 Developers must provide at least basic information on what each new 
 feature does and what each feature (drop down box, radio button, etc) is 
 for. Without this users need to ferret through hundreds of emails and 
 forum posts, and pester the developers anyway. It is easier for devs to 
 provide a simple skeleton -- this does this, that does that, here is a 
 link, check out this bug etc. All this information is available at the 
 developers fingertips while they are working on the new feature anyway 
 -- it is just committing 30 minutes at the end to put some details down 
 on he page.
 
 With this basic information, documenters are better equipped to present 
 the feature in context and explain how it should be used.

  going to get many contributions from users, leaving the documentation to
  be written only by developers.
 
  I try to keep the Processing documentation up to date, but only
  documenting the interface itself and the framework, not the algorithms.
  That's the reason why a large part of algorithms in Processing are not
  documented. Fortunately, some users have contributed documentation, and
  they have added descriptions of several algorithms, but the have done
  that *after* using the (hitherto undocumented) algorithm and becoming
  familiar with it. No one is going to document something that he cannot
  use yet.
 
  Let's encourage developers to commit features when they are well
  documented, but let's also give some flexibility, since that's not
  always going to be possible.
 
  my 2 cents

Re: [Qgis-developer] [Qgis-user] Stress about release plans

[Otto Dassau]

Hi Nathan,

thanks for the offer, but this is not the problem. After feature freeze we
currently do a git log --since=date --grep='FEATURE', that's ok. And Tims
changelog is also very helpful and often already fine as a beginning.

The result is in the wiki: http://hub.qgis.org/wiki/17/ManualTasks

But this covers not all changes we need to document nor does it usually
describe the usage. We still we have to search the web, so it would be great
to have a simple skeleton with a short description of all functionality of a
feature from the developers, if that is possible. 

Maybe we can offer 2 ways. If developers write about features in their blog
and describe how it works, as you do, you could just add the link
somewhere where documenters can look it up. For others a simple
documentation skeleton could be used as a standard.

Whatever we finally use, it would be good to improve the current procedure.

Regards
Otto

[Qgis-developer] attribute table row cache

[Otto Dassau]

Hi,

the option Attribute table row cache under settings - options - data
sources makes it possible to save the last loaded N attribute rows so that
working with the attribute table will be quicker. The cache will be deleted
when closing the attribute table.

What is the maximum number of lines here and what happens, if I set it to
0 - would that cache all line or no lines? I would like to load the complete
attribute table from an external database into the cache. Is that option
possible?

Thanks

Re: [Qgis-developer] [Qgis-user] Stress about release plans

[Otto Dassau]

Hi,

I would prefere another solution instead of changing the releases. The
documentation team is in the same situation. We are always behind the
releases, but the problem I see is that there are not enough people working
on the documents. At the moment we were not even able to start updating the
manual for 2.4 yet :(. 

From my experience, we get many new features for every release because
developers work together on the master source.

For some reason trainers prefere starting from scratch working on her/his
own documents and training material, which is ok, of course but leads into
the situation Lene discribed.

Here are two ideas that come to my mind:

a) Trainers could combine their forces and prepair general training materials
together that everybody can use and extend. All tools and the document basis
is available and provided by QGIS project in the documentation repository. I
know there are many people conducting trainings on QGIS, if they all work
together as developers already do, we would probably be in a much better
situation.

b) An idea that already works for the development of QGIS features is paying
some amount or percantage of each development for good documentation and
training material. Many new features in QGIS are payed by customers. But
usually customers and developers don't think about also spending an
additional little amount to document the feature in the QGIS docs and
training material. I don't know why, but that's reality.

So for me, the problem is not just about changing the releases cycles. It is
more about bringing documenters and trainers closer to the project again to
combine their forces. And to make customers/users/developers aware, that
documentation and training material is an important part of the software and
should not be forgotten and maybe automatically added to an offer, if new
(payed) features are added.

Regards,
Otto

 Hi,
 
 This is not a mail about bugs or issues on a special feature – just a
 matter of time.
 
 Right now I´m preparing a 3 week intensive GIS course at university level
 - looking forward to these annual events. But I get stressed when I see
 that there are only 94 days until next version of QGIS. Because in
 November I start over again with a 8 week course and in February a 3 week
 course, in may a 3 week course. All in all we have more than 140 students
 learning QGIS every year – and they are impressed of this program!!!
 
  
 
 I love getting new features in the program, but fear the work to run
 through every assignment, every video and being a bit unsure how the
 program works in the latest version on the different platforms.
 
 Small changes which I haven´t noticed and therefore unaware of. So a new
 version so soon gives me a lot of stress and so many hours of work –
  hours which could be used to ex. testing.
 
  
 
 When I ask users to download the program they take the official latest
 version – sometimes with bugs included… It gives an impression of an
 unprofessional product (not my words), it gives me- and others hard times
 to fix or explain. I´ve been talking to other users/administrators who has
 the same experience.
 
 What if we had :
 
 ·    A long term stable version for ex. 12 months with bugfix only
 
 ·    A developer version for 4 months with new features and bugfixes
 = Stable version with short bugfix-period = New developer……..
 
  
 
 I do know it will give the developers more work – I do know it will cost
 more money – But I´m sure a lot of administrators will recommend,  use and
 support if we get a more stable environment.
 
 So please – consider another release plan in the future.

qgis-web-client-error.log I get following error

malformed header from script. Bad header=credentials for dbname='testdb':

I set up the qgs project file on my local PC and the error occurs, when I
copy the file to the server, where postgis and QGIS server is installed.

Thanks for any hints

[Qgis-developer] New QGIS case study from Antarctica

[Otto Dassau]

Dear Community,

we have a new QGIS case study written by Anders Skoglund and Kenichi
Matsuok. Anders is GIS specialist and Kenichi glaciologist at the Norwegian
Polar Institute.

The case study is about Quantarctica, a collection of Antarctic geographical
datasets, developed as a tool for the research community, for classrooms and
for operational use in Antarctica.

You find the whole story here:
http://www.qgis.org/en/community/qgis-case-studies/antarctica.html

Thank you very much Anders Skoglund and Kenichi Matsuok for your
contribution!

Re: [Qgis-developer] update plugin to QGIS 2.0

[Otto Dassau]

Hi,

thanks for the hint. And if I need the value of the raster? If I understand
correctly, ident will always be 1, if I have a 1 band raster layer. But how
can I get the value at QgsPoint(x,y) of the raster? I don't understand that
from the value tool plugin.

In QGIS 1.8 I use :

success, data = layer.identify(QgsPoint(x,y))
   for band, value in data.items():
   return value

and in QGIS 2.0:

ident = 
layer.dataProvider().identify(QgsPoint(x,y),QgsRaster.IdentifyFormatValue).results()
   ?

Thanks again

Otto

 results() returns a QMapint, QVariant (one item for each band), it
 does not return a tuple, so you should actually call
 
 ident =
 layer.dataProvider().identify(QgsPoint(x,y),QgsRaster.IdentifyFormatValue).results()
 
 and then test that ident is not empty (i,e. ident is not None and
 ident.iterkeys() is not None)
 
 for each band, if the point is outside of the raster extent or is
 nodata, the value will be a null QVariant (i.e. QVariant()) which in
 python is None.

 no,  ident will be a dict with an element of key 1
 
 you get exactly the fist band's value at the point with ident[1] .
 
 the key of the map is the band number, and the value is the value (or
 None if nodata/out of bounds)
 
 so without any error checking you would do
 
 ident =
 layer.dataProvider().identify(QgsPoint(x,y),QgsRaster.IdentifyFormatValue).results()
 return ident[1]

Re: [Qgis-developer] get mean of pixel values within defined area around current mouse position

[Otto Dassau]

Hi,

I have a question to update the code I sent in a former below to QGIS 2.0.
Again I need the mean value, currently use:

vpoly = QgsVectorLayer(Polygon, pointbuffer, memory)
feature = QgsFeature()
feature.setGeometry(QgsGeometry.fromPoint(QgsPoint(3517601,5406205)).buffer(1,5))
provider = vpoly.dataProvider()
provider.addFeatures( [feature] )
vpoly.commitChanges()
stats = QgsZonalStatistics(vpoly,/path/to/corine2006_z0_test_gk3.tif)
stats.calculateStatistics(None)
allAttrs = provider.attributeIndexes()   
for feature in vpoly.getFeatures():
   for attr in feature.attributes():
  return attr

attr in this case is probably the sum as I can see from the results, but I
need the mean again, as below. 

For QGIS 1.8 k==0 is number of pixels, k==1 is sum, k==2 is mean, see below.
But something like return attr[2] doesn't work. It says TypeError: 'float'
object has no attribute 'getitem'. Maybe someone has an idea how to solve
this?

Thanks a lot

 I wanted to give a short feedback. Finally my solution for qgis 1.8 with

   Not sure it's the best way but I did something similar with these
   workarounds:
   
   A - with gdal:
   1 - the user click and you get your buffer. (already done)
   2 - use gdalwarp with -cutline and *-*crop_to_cutline options to
   extract a new raster. (python subprocess)
   3 - read the created raster in a numpy array to do all the statistics
   you need.
   
   B - with matplotlib:
   1 - with the buffer: create an array of the vertices
   2 - read the raster into another numpy array
   3 - use the points_inside_poly function of matplotlib lib to
   create a numpy mask.
   
   Not tried but postgis raster should do the job.

of a raster layer within a defined buffer for the current mouse
position (not for
an existing point layer).
   
For the buffer it works:
   
...
feat.geometry().asPoint()
(3.5176e+06,5.4062e+06)
buff_geom = feat.geometry().buffer(1000, 5)
buff_geom.asPolygon() [[(3.5186e+06,5.4062e+06),
(3.51855e+06,5.4059e+06), (3.51841e+06,5.40562e+06),
(3.51819e+06,5.4054e+06), (3.51791e+06,5.40525e+06),
(3.5176e+06,5.4052e+06), (3.51729e+06,5.40525e+06),
(3.51701e+06,5.4054e+06),...]]
   
but now I try to find a solution to query the raster pixels within
the buffer zone and calculate the mean, but I don't know how and if
this is possible in QGIS 1.8 at all. I found QgsZonalStatistics, but
that doesn't work for my task.
   
Does anybody have a solution for this or a better idea, how to solve
this?
   
Thanks
   
Otto

Re: [Qgis-developer] get mean of pixel values within defined area around current mouse position

[Otto Dassau]

Hi,

I wanted to give a short feedback. Finally my solution for qgis 1.8 with some
help from Anita was to create a buffer polygon around the point as a memory
layer and calculated the mean value with QgsZonalStatistics. Here is the
code I used, maybe useful for others:

from qgis.analysis import QgsZonalStatistics
from PyQt4.QtGui import *

vpoly = QgsVectorLayer(Polygon, pointbuffer, memory)
feature = QgsFeature()
feature.setGeometry( 
QgsGeometry.fromPoint(QgsPoint(3517601,5406205)).buffer(1,5))
provider = vpoly.dataProvider()
vpoly.startEditing()
provider.addFeatures( [feature] ) 
vpoly.commitChanges()
stats=qgis.analysis.QgsZonalStatistics(vpoly,/path/to/rasterlayer.tif)
stats.calculateStatistics(None)
allAttrs = provider.attributeIndexes()
provider.select(allAttrs)
provider.nextFeature(feature)
attrs = feature.attributeMap()
for (k,attr) in attrs.iteritems():
  if k==2:

QMessageBox.information(qgis.utils.iface.mainWindow(),'Info',attr.toString())

Otto

  A - with gdal:

  2 - use gdalwarp with -cutline and *-*crop_to_cutline options to

  3 - read the created raster in a numpy array to do all the statistics you
  need.
  
  B - with matplotlib:

Re: [Qgis-developer] qgis-webclient - sample data 200M

[Otto Dassau]

Hi Andreas,

for 50M to 100M you get a warning, but the HYP_50M_SR_W.tif is 166.94 MB and
that's too much. For both files I resampled output files from 0.03 to 0.08 
degree
pixel resolution. That is 4500 x 2250 instead of 10800, 5400 pixel. Still
sufficient I think.

Both would now be below 50M of size. Is that ok? Then I would commit the
changes.

Otto

 Thank you for pointing this out. Isn't this just a warning?
 
 If you have a good test project with smaller data to share I am happy to

 I just did not have the time to work on the sample project.
 
 Anyway - the file could be checked out by hand or it can just be ignored.

Re: [Qgis-developer] Building QGIS 1.8 in openSUSE 12.3

Hi Nikos,

why don't you use the packages from application:geo repository:
http://hub.qgis.org/projects/quantum-gis/wiki/Download#24-openSUSE

And if you need to compile, you can take a look at the spec file here:

Maybe this helps

 I recently switch (and still am in a testing phase) from (K)Ubuntu to

 I am trying to  compile QGIS 1.8 from source but I have some difficulties

 I think I have (already) installed build dependencies with

 Reading installed packages...

 Nothing to do.
 
 
 
 Next, I have instructed in /etc/ld.so.conf.d/osgeo.conf
 
 /osgeo/src/Quantum-GIS/build/output/lib/
 
 
 
 The configuration (ccmake) goes fine and then, the compilation fails:

 The file mentioned above exists in

Re: [Qgis-developer] changing srs.db with coordinate system updater Plugin

 The problem is, that the projection according to the new parameters does

 If I define a user defined projection in QGIS with the new parameters, the

Hi,

I would also like to keep it abstract and only Qgis as text in the logo and
not Quantum GIS. I like the idea of #33. It looks still like an evolution of
our current logo with arrow.

http://99designs.de/logo-design/contests/qgis-needs-logo-210397/entries/33

But I would also like to see #33 more abstract and less colourful as in #65.

http://99designs.de/logo-design/contests/qgis-needs-logo-210397/entries/65

So my favourite would be a mixture between #33 and #65 and only with QGIS
and not Quantum GIS as text.

  I made a pull request fixing this issue. If a url is detected

[Qgis-developer] Website about the activities at the developer meeting in Valmiera

[Otto Dassau]

Dear Community,

as you can see from the comments on the mailing lists, the ninth hackfest in
Valmiera was a great success and very well organized by the latvian team
from SuGIS - Maris Nartiss, Peteris Bruns and Raitis Berzins. 

On behalf of the PSC I would like to thank all participants, organizers,
sponsors and donors who spent their time, energy and money to make QGIS
again a little better. 

I added a webpage with information and further links about the people, their
activities and photos from the Valmiera event here:

http://www.qgis.org/en/developer-meetings/valmiera-42013.html

All web and doc content is build from master branch and additionally the

You find the current status here:

http://docs.qgis.org  = links to http://docs.qgis.org/2.0/html/en/

  Hi all.
  Back from a short meeting with Otto, Werner, Raynold, and Alessandro.
  Main conclusions:
  * we should move all the nerdy stuff to another section of the site,
  quite separate (but readily accessible) from it
  * as a consequence, the user website should be even leaner and
  simpler, listing only the info really essential for the users
  * we need to improve the current script to build up the website based
  on current GH, so everybody can see and comment the results
  * we need a suitable theme, but we can publish the pages with the
  current one until we find a better one
  * we *need help* on a small but important issue: adding links to the
  table of content, in the form:
  
  .. toctree::
  :maxdepth: 2
  :hidden:
  
  website/download
  docs/user_manual/index
  docs/gentle_gis_introduction/index
  http://plugins.qgis.org
  
  works, but the resulting link has a label None. Does anybody know
  how to add a proper label to it? I tried with the normal rst syntax
  `Plugins http://plugins.qgis.org`_ but it does not work.
  This is a stumbling block for the publication.
  * in the meantime, we are migrating content.
  
  Thanks to all.

 Hi Otto,
 
 great, thanks!
 
 I've not been looking in the scripts, but from the url's it seems that 
 the 1.8 and the 2.0 are full copies of the Documentation tree.
 
 While I thought, that only the Manual (and probably the Python Cookbook) 
 would be 'versioned'. The rest of the website and docs will probably not 
 change during a version bump?

the website stuff were just dummies in the 1.8 branch, I removed them so
with the next build we will only have the docs manual and PyQGIS Coobook
available. And maybe even the Cookbook could be removed?

 Am I right in this?
 If not, it will be more work for website translators to keep up with 
 every version.
 
 (by the way, because of this viewpoint I thought it would be easier to 
 have just one 'tree' in github)

If you look at the script on the server I currently use 2 clones, build them
seperately and copy things we need from the 1.8 clone into the output folder
of the master clone. This makes it quite flexible, if we want to decide what
to show on the website and easy to handle.

And therefore it was not necessary to make many changes to the pre/post
translate scripts, which are not only used on the server but also locally by
doc writers and translators. 

Instead I mostly adapted the build_qgis-docs.sh script on the server.

If you have another or better solution, we can improve it of course.

 Richard Duivenvoorde

 Hi all.
 Back from a short meeting with Otto, Werner, Raynold, and Alessandro.
 Main conclusions:
 * we should move all the nerdy stuff to another section of the site,
 quite separate (but readily accessible) from it
 * as a consequence, the user website should be even leaner and
 simpler, listing only the info really essential for the users
 * we need to improve the current script to build up the website based
 on current GH, so everybody can see and comment the results
 * we need a suitable theme, but we can publish the pages with the
 current one until we find a better one
 * we *need help* on a small but important issue: adding links to the
 table of content, in the form:
 
 .. toctree::
 :maxdepth: 2
 :hidden:
 
 website/download
 docs/user_manual/index
 docs/gentle_gis_introduction/index
 http://plugins.qgis.org
 
 works, but the resulting link has a label None. Does anybody know
 how to add a proper label to it? I tried with the normal rst syntax
 `Plugins http://plugins.qgis.org`_ but it does not work.
 This is a stumbling block for the publication.
 * in the meantime, we are migrating content.
 
 Thanks to all.

[Qgis-developer] doc translation

[Otto Dassau]

Hi,

we also had a small discussion about the current translation process and we
think it would be the best solution for now, if we only use the local
translation process and not transifex. We need to find out first a good
workflow, how the conversion between tx and git works without conflicts.

Do we have any transifex/git experts on this list, who can have a look?

Apart from that it would be important to have a look at the documentation
of the local translation process and see if we need to improve this for
normal users, who don't know much about git, github, linguist,  Is there
someone, who is willing to do that? The document is here:

https://github.com/qgis/QGIS-Documentation/blob/master/source/docs/documentation_guidelines/do_translations.rst

 agreed, a more comprehensive sample package would be very useful.
 I would not object splitting it in two, a basic package, kept small, and a

 Obviously, this make sense if there is a maintainer of the package, to
 keep it updated and add new stuff as it comes out.

Hi,

the QGIS-documentation repository should be ok again. Unfortunately we

morning again. I hope nothing is lost - but please check.

If you are a translation maintainer, please create a new fork and organize
with your translators, that they update/fork their repo again as well.
We are sorry for the inconvenience and please ask on the community-team

[Qgis-developer] 10th QGIS hackfest will be in Brighton (autumn 2013)

[Otto Dassau]

Dear QGIS Community,

as you probably know, the FOSS4G conference 2013 will take place in
Nottingham from 17th - 21st September and we are happy that we are able to
combine it with the 10th QGIS hackfest.

Saber Razmjooei and Peter Wells from Lutra Consulting offered to host the
hackfest in Brighton from 12.-16. September 2013 right before the FOSS4G
(17th-21st September 2013). 

For people who are interested in going to FOSS4G afterwards it is not a long
trip from Brighton to Nottingham and we will try to organize the transfer.

As usual you will find all information in the wiki (not much to see yet):
http://hub.qgis.org/wiki/quantum-gis/10_QGIS_Developer_Meeting_in_Brighton_2013

We will start planning after the hackfest in Valmiera, which will take place
soon from 11th - 14th of April 2013:

[Qgis-developer] select a loaded raster layer from qgis legend into python plugin

[Otto Dassau]

Hi,

I would like to write a small python plugin to analyse some raster data,
but I haven't managed to select a loaded layer yet. I searched the howtos and
found several simple examples about:

# get the currently active layer
  layer = self.iface.mapCanvas().currentLayer()

but as I said I would like to select one of the loaded raster layers from the
qgis legend using a QtGui.QComboBox in the plugin dialog. At the moment I
tried the getRasterLayersNames() function I found in several other plugins
but it seems I am missing something, because the raster layers are not
selectable. Can someone point me to a simple example to understand the
general procedure?

Thanks a lot
Otto

Re: [Qgis-developer] select a loaded raster layer from qgis legend into python plugin

[Otto Dassau]

Hi Matthias,

thanks for your help. I guess it is similar to what I found?

def getRasterLayersNames():
layerList = []
layerMap = QgsMapLayerRegistry.instance().mapLayers()
for name, layer in layerMap.iteritems():
if layer.type() == QgsMapLayer.RasterLayer and
  ( layer.usesProvider() and layer.providerKey() ==
  'gdal' ): layerList.append( unicode( layer.name()))
return layerList

If I understand correctly your function selects all raster layers from
QgsMapLayerRegistry. Now I would like to visualize the layer list in the
combobox (InRastA) of the plugin dialog file. I found something that works
for vector layers:

def manageGui(self):
myList = []
self.ui.InRastA.clear()
myList = initLayerCombobox()
self.ui.InRastA.addItems( myList )
return 

But is doesn't work for raster that way, if I use your function. How is it
possible to make the raster layers selectable / show up in the plugin dialog?

Regards
Otto

[Qgis-developer] New case study about the Fundy Footpath Trail

[Otto Dassau]

Dear Community,

I am pleased to announce a new case study, this time from the Fundy coast of
New Brunswick, Canada. 

There is a wonderful trail created, maintained, and promoted by a group of
volunteers known as the Fundy Hiking Trail Association Inc. (FHTA)(1975). As
a non-profit organization the FHTA raises funds for its activities through
the sale of guidebooks that include a trail map.

The case study is about creating the Fundy Footpath Trail Map with Quantum
GIS. Author is Jarrett Totton. He is a GIS Technologist living in Alberta,
Canada.

You find the case study here:
http://www.qgis.org/en/community/qgis-case-studies/new-brunswick-canada.html

Thank you very much for this contribution!

Kind Regards
Otto
