I have a polyline layer of rivers in England (one line, only attribute is length), and I need to divide it into regions so that I can work out the length of rivers in each region (the green bit is the line layer in the picture.
Is there a way to clip the line by the polygon layer, so that it creates one line per region? (a multi-part feature is fine)
Just to add - I've tried the clip tool, but it just clips to the outline of the whole polygon layer - so doesn't split up the regions...
