[Qgis-developer] Kriging interpolation functionality in QGIS?

2015-09-25 Thread Stefan Keller

Hi,

I'm looking for a Kriging interpolation from an irregular point data
set to raster data in QGIS without dependencies, if possible. There's
1.   Interpolation plugin (C++) [1]
2.   „Raster Interpolation“ plugin von Denis Rouzaud (Python) [2]

I know that GRASS and SAGA implemented Kriging [3].
But these are are dependencies I'd like to avoid in order to make QGIS
even more easier to use.
AFAIK even Denis' "Raster Interpolation" plugin requires Scipy
separately installed.

So eventually, I'm considering to extend "Raster Interpolation" Python
plugin (or [1])
Any suggestions or activities regarding this?

FindGEOS.cmake changed in that commit, introducing the new variable 
GEOS_CPP_LIBRARY. It looks like a simple reconfigure of an existing 
build directory is insufficient for cmake to pick up that change, and 
people have reported that it is necessary to start from an empty build 
directory for the build to succeed, perhaps removing the CMakeCache 
might also be sufficient. Anyone with enough low-level knowledge of 
cmake to explain why the reconfiguring does not pick up the changes in 
FindGEOS.cmake ...?

2015-09-25 Thread Stefan Keller

Hi Barry

Many thanks for your explanations and hints.
So from a pragmatic point-of-view ("80/20 pareto rule"):
Do you think Inverse Distance Weighting (IDW) would do the job as well,
since Kriging has so many parameters to fiddle around and to understand?

 You want Kriging in QGIS? You now have to implement a full
statistical analysis system in QGIS. Kriging is hard, or even
impossible to do properly as an automatic points-to-raster process
without statistical diagnostics. You'll need to plot your variogram.
You'll need to fit your variogram. You may need to transform your
variables, and transform results back (and the back-transform of
Kriging standard-errors is not trivial).

 The simplest points-to-raster Kriging system I've seen is autoKrige
from the R automap package. Even so this has about 7 parameters and
options to choose from. Plus working in R makes it easy to plot
diagnostics and histograms and do transforms and testing

 If you want to try all that, there's a few python kriging
implementations that you could use, or this blog poster shows how to
do it from scratch with basic matrix ops:

[Qgis-developer] QCA lib dependency for master

2015-09-25 Thread Larry Shaffer

Hi,

With PR #2330 merged, there is now a dependency upon the Qt Cryptographic
Architecture (QCA) library and one of its plugins [0] for master builds.

See first two posts of the old PR #1838 for information on getting QCA
installed for your system [1]. I will update INSTALL tonight or tomorrow.

QCA is GPL2-licensed tool now part of the KDE project [2]. Its usage in
QGIS has a run-time dependency upon QCA's OpenSSL plugin (qca-ossl), which
keeps QGIS from directly linking to OpenSSL, thereby avoiding any annoying
export restrictions. You can install other QCA plugins, but qca-ossl is
prioritized over any others in QGIS startup code. If the plugin is missing
the new authentication system will gracefully disable itself (let me know
if it does not).

Latest QCA version is 2.1.0 (and recommended), which builds on all major
platforms using CMake and includes all available plugins in the build
process. However, the code has been tested against version 2.0.3 (package
on Ubuntu 12.04), which requires separate building of plugins.

The Travic CI builds already have the necessary bits added for QCA in their
setup scripts.

Re: [Qgis-developer] QGIS 2.10 - weird black circles

2015-09-25 Thread William W

Hi

I am also having this problem when publishing a layer as wms. I have tried
turning off diagrams on the affected polygon layer (and all others) and
saving the QGIS project but the diagram tags (Pie chart) remain in the QGS
file. I have tried deleting the layer from the QGS file but it appears again
as soon as I save the QGIS project. 

I have also noticed that when I remove the layer from the QGIS project and
re-add it, the diagram tags in the QGS file are not present but when I
change the symbol (colour of a simple fill) the diagram tags appear again.

Any help appreciated

William

[Qgis-developer] TypeError: C++ type 'QgsFeatureIds' is not supported as a signal argument type

2015-09-25 Thread //./\\-/_.\\

Hi QGIS developers!

I got strange error with the 'commitedFeaturesRemoved' signal.
See: 
http://www.qgis.org/api/classQgsVectorLayer.html#a520550b45603ed20d593b1050768bd97

I try on python console (with any active layer on editing mode):
>>> layer = iface.activeLayer()
>>> def listener(s, l):
>>>  print s, l
>>> layer.committedFeaturesRemoved.connect(listener)

It returns `TypeError: C++ type 'QgsFeatureIds' is not supported as a signal 
argument type`

Now replace `layer.commitedFeaturesRemoved.connect(listener)`by:
>>> from PyQt4.QtCore import QObject
>>> from PyQt4.QtCore import SIGNAL
>>> QObject.disconnect(layer, SIGNAL(r"committedFeaturesRemoved()"), 
>>> listener)

No error, but it returns `False`.

If I delete some features and switch off editing mode, it returns nothing! No 
print! The signal doesn't work(?)

After exchanging a few message with some people on irc #qgis, the error only 
appears with latest QGIS version on OSX10.10.5. (it works well with 2.8.2). 

Maybe someone that has approached the same problem... and solved it?

Re: [Qgis-developer] New authentication system ready

2015-09-25 Thread Larry Shaffer

Hi devs,

As you can see in the PR [0], I've fixed up some things, including adding
the ability to edit an authentication ID, which will help with workflows
where users need to share projects. I've also cleaned up the interface and
moved most PKI-related dialogs out of the main Options view.

I am working on another widget that can be used for the Handle Bad Layers
and the Layers Properties dialogs. That should work for most issues
occurring when sharing projects and when users open projects with missing
authentication IDs. I've also added feedback in the selector widget when it
tries to load a config ID that is missing.

I should have those bits done today, then it's mostly work on finishing the
unit test migration to C++.

**However, I would like to merge this now, since it is in a very good state
for doing so. Does anyone have objections with me merging this?**

[Qgis-developer] Metasearch throwing an error

2015-09-25 Thread Paolo Cavallini

Hi all,
the current version of MS returns an error when adding default servers:
Cannot parse XML file: not well-formed (invalid token): line 11, column 129
When reinstalling, I get:
Impossibile caricare il plugin MetaSearch a causa di un errore chiamando
il metodo classFactory()


Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 219, in
startPlugin
plugins[packageName] = package.classFactory(iface)
  File
"/home/paolo/Scrivania/butta/carto_qgis/python/plugins/MetaSearch/__init__.py",
line 28, in classFactory
from MetaSearch.plugin import MetaSearchPlugin
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 478, in
_import
mod = _builtin_import(name, globals, locals, fromlist, level)
  File
"/home/paolo/Scrivania/butta/carto_qgis/python/plugins/MetaSearch/plugin.py",
line 31, in
from MetaSearch.dialogs.maindialog import MetaSearchDialog
  File "/usr/lib/python2.7/dist-packages/qgis/utils.py", line 478, in
_import
mod = _builtin_import(name, globals, locals, fromlist, level)
  File
"/usr/share/qgis/python/plugins/MetaSearch/dialogs/maindialog.py", line
53, in
from MetaSearch.util import (get_connections_from_file, get_ui_class,
ImportError: cannot import name serialize_string
Should I open a ticket?
