Re: [Qgis-user] Adding GRASS Vector layer
I don't know about OSX, but on Linux GRASS GIS 7.0 is not yet supported in QGIS (grass-gdal plugin is not yet working I believe). Try if a vector layer in GRASS 6.4 works.

Re: [Qgis-user] Issues with Print Composer and QGIS Server
Hi, Are you testing from QGIS Web Client? And are your units in degrees? If yes, there is a problem that the grid interval is kind of hard-coded in the file site/scripts/QGISExtensions.js - search for grid_interval. This is only optimized for meters. One need to fix this issue for degree based units or make it user-defineable in GlobalOptions.js - you can issue a bug/feature request for this in hub.qgis.org. Sorry about that - initially this was only for our inhouse purpose where we do not deal with degree-based projection systems.

Re: [Qgis-user] How to run SEXTANTE algorithms outside of QGIS Python console?
Hi Paolo, I just disabled digest mode, but hopefully this will be part of the same thread. My question is more specifically about SEXTANTE, if there is a better forum for this please let me know. My question is how to run SEXTANTE algorithms outside of QGIS Python console. Is this possible? The closest answer I found was on StackExchange here: http://gis.stackexchange.com/questions/28701/how-to-run-sextante-algorithms-outside-of-qgis-python-console The code provided runs, but when I add a call to sextante.runalg it raises an error related to iface, which seems to be something from QgisInterface.instance(). Specifically I get an AttributeError because iface == None. Another related post indicated that this kind of error is because the code is being run outside of QGIS and therefore there is no iface that could be referenced. In the code there is a commented out line that looks like a QGIS instance is wanted, but it wasn't working. Any suggestions? What would be most helpful is if someone could modify the code to include a single SEXTANTE call that executes any algorithm, preferable one from GRASS. Thank you. Here is the code: import sys from PyQt4.QtGui import QApplication from sextante.core.Sextante import Sextante def main(): main function or something # as per http://qgis.org/pyqgis-cookbook/intro.html#using-pyqgis-in-custom-application from qgis.core import * import qgis.utils app = QApplication(sys.argv) # supply path to where is your qgis installed QgsApplication.setPrefixPath(C:/OSGeo4W/apps/qgis, True) # load providers QgsApplication.initQgis() # how??? # qgis.utils.iface = QgisInterface.instance() Sextante.initialize() run_script(qgis.utils.iface) def run_script(iface): this shall be called from Script Runner Sextante.alglist() Sextante.alghelp(saga:slopeaspectcurvature) if __name__==__main__: main() -Martin Date: Wed, 15 May 2013 08:06:57 +0200 From: Paolo Cavallini cavall...@faunalia.it To: qgis-user@lists.osgeo.org Subject: Re: [Qgis-user] How to run SEXTANTE algorithms outside of QGIS Python console?

[Qgis-user] sextante QGIS geoalgorithms
Hi guys, none of the geoalgorithms of Qgis work through the sextante toolbox. For example the reproject layer gives: Traceback (most recent call last): File /home/matteo/.qgis2/python/plugins/sextante/core/GeoAlgorithm.py, line 145, in execute self.processAlgorithm(progress) File /home/matteo/.qgis2/python/plugins/sextante/algs/ftools/ReprojectLayer.py, line 71, in processAlgorithm features = QGisLayers.features(layer) File /home/matteo/.qgis2/python/plugins/sextante/core/QGisLayers.py, line 206, in features return Features(layer) File /home/matteo/.qgis2/python/plugins/sextante/core/QGisLayers.py, line 214, in __init__ self.layer.dataProvider().rewind() AttributeError: 'QgsVectorDataProvider' object has no attribute 'rewind' Other algorithms give similar errors.

You can try : li = qgis.utils.iface.legendInterface() g1 = li.addGroup(g1) g2 = li.addGroup(g2,True, g2) I never attempted that since addGroup() returns an index at least according to the documentation not a pointer. In fact if you do the following (qgis 1.8) it gets listed in group g1 not g2 g3 = li.addGroup(g3, True, g2) On 05/15/2013 09:25 AM, David J. Bakeman wrote: On 05/14/2013 03:02 PM, David J.

Does it work for you? I built master from source and it doesn't work there either. P.S. I think this response is in plain text so shouldn't get rejected. The above seems like it should work but it doesn't.

Re: [Qgis-user] sextante QGIS geoalgorithms
Matteo I am afraid you are using an old version of SEXTANTE, not compatible with the new QGIS API Remove all 'sextante' folders from you .qgis2 folder, and that will make QGIS use just the core version.
