Hello,
I have a question related to how the function "intersect" works. I have
two shapefiles, one of lines the others of polygons. I would like to get
into a shapefile the polygons that are intersected by the lines. I tried
unsuccessfully using Vector > Geoprocessing tools > intersect. In this
case, if the input is the lines and the intersect the polygon, I can
split the lines according to the border of each polygon, and each
segment is identified by the polygon name in the attribute, but this is
not what I want to. If I do the reverse, I get an empty polygon vector
file.
What I want is the shapefile of the subset of polygons that intersect
the lines...
Any idea about how to proceed ?
Patrick
PS: for info, the expected result can be easily obtained in R, package
'rgeos', function 'gIntersection'
