I have a polygon vector layer and a line vector layer in a form of grid (they are both in the .shp format). I need to split polygons by these lines.
I tried digitizing tools but the problem is that it deals only with 1 line at a time and I have more than 52,000 lines. It will take a ridiculously long time to split it manually. How can it be done for all the lines?
I have QGIS 2.18.
