[Qgis-user] Help with polygon

[Mariana Buzzi]

Hello Everybody!

I have a polygon which occupies my area of study. Within it I have scanned
with another polygon, a unit of landscape, the plateau. Now I must perform
manual scanning other landscape unit, the coastal canyons. To avoid
manually do it, I wanted to perform some operation that automatically to
the study area, "restin"g area of the plateau and so I can give the area of
coastal canyons.

Any ideas?
Regards,
Mariana
