I am very new to Python scripting in QuantumGIS, so bear with me please.

I am trying to use the QgsOverlayAnalyzer class in QuantumGIS (http://www.qgis.org/api/classQgsOverlayAnalyzer.html#details) to automate the intersection between different layers (I have plenty of intersections to do).

However, I can't get it to work in the python console.. assume I want to intersect layer1 with layer2, and write the results in C:\shapefile.shp, I am trying something like this with no success:

QgsOverlayAnalyzer.intesection(layer1, layer2, "C:\shapefile.shp", false, 0)

The error I make must be quite serious, as the message I get is:

NameError: name 'QgsOverlayAnalyzer' is not defined

Any help on this is very much appreciated.



It seems that the correct answer is here.

You can access to that object importing the analysis module:

from qgis import analysis
  • Diegogb, thanks a lot! this is exactly what I was looking for, now it runs like a charme! Quite depressing though that yesterday I surfed the web for a few hours without managing to come across the page you linked me! – Dom Mar 20 '13 at 9:22
