I have spent quite a bit of time looking for a clear answer this topic and have still been unable to really accomplish my goal of accessing PyQGIS in a stand alone script.
Parts of answers have been provided across many different questions such as:
The most thourough Answer that I have found was provided by @gene here.
What I particularly am interested in, is being able to write scripts that can call on both Arcpy, and PyQGIS. I have set both PATH and PYTHONPATH system variables according to the PyQGIS cookbook documentation as:
C:\OSGeo4W\apps\qgis\bin,%PATH%;C:\Python27\ArcGIS10.2\Lib\site-packages\PyQt4;C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\Tools\Binn\;C:\Program Files\Microsoft SQL Server\100\DTS\Binn\;C:\Program Files (x86)\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\;C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PrivateAssemblies\;C:\Program Files (x86)\Microsoft SQL Server\100\DTS\Binn\
I am starting with this script:
from qgis.core import * QgsApplication.setPrefixPath("C:\OSGeo4W\bin\qgis.bat", True) QgsApplication.initQgis() # or your solution # read a shapefile layer = QgsVectorLayer('H:\DATA\Airfields_AB.shp', 'Airfields', 'ogr') layer.isValid() True # loop through layer for elem in layer.getFeatures(): geom= elem.geometry() attr =elem.attributes() (processing)
I am looking to avoid batch scripts that set the appropriate settings, but rather call them from inside the Python script. The optimal scenario for me would be to use the IDLE in the ArcGIS 10.2 folder to run the preceding code. I am using a Windows 7 machine with ArcGIS 10.2 and QGIS 2.01.
Currently the results of this code is:
Traceback (most recent call last): File "F:\Users\...\PyQGIS_Test_01.py", line 1, in <module> from qgis.core import * ImportError: DLL load failed: The specified module could not be found.
