I'm having some trouble applying my Python skills to develop some scripts in PyQGIS. For me it's far simpler to write it in ArcPy, but then again I wouldn't get that much satisfaction after finishing my project. Trying to work with open source tools as much as possible.
In short, for now I want to write a Python script that takes in a shapefile and from that generates another one with some specific attribute data related to buildings. If I were doing it in ArcPy, my algorithm would be the following: use the MakeFeature Layer_management, then perform a SelectLayerByLocation_management, within the selection select the data you need, and then create another layer with desired data.
How could I this in PyQGIS? One idea, reading the PyQGIS Cookbook, to use .getFeatures(), QgsVectorFileWriter to write the shapefile, but how do I perform the query?
Many thanks!
