I have a series of shapefiles that include both polygons and multipolygons. I am using ogr to extract them in wkb, and them I am using shapely to check if a point fall inside a polygon (or a multipolygon). However, examining some of the polygons in wkb I realized that many of them have inner rings (i.e. I have a set of coordinates describing the first, outer polygon, and a set of coordinates describing the inner polygon/s). Does the shapely
within function take care of this, I mean, does it return
True only if a point falls in the area delimited by outer and inner polygons? And are the inner polygons always supposed to be holes?
I am sorry, perhaps these are really dumb questions, but I am completely new to this kind of analyses and, despite my efforts, I could not find some clear information about these doubts. Thanks in advance for your help.
