MI Re: new region where two regions overlap

[SOLOMON ISLANDS POPULATION CENSUS]

Dear all

I have a health zone layer and a clinic buffer  layer (10km circles) Some of
the buffers extend into the sea, in these cases I just want the area on land
i.e. the overlap between the buffer and the health zone. I can do it
manually, i.e. trace round the desired area with autotrace, then return the
area of the new region, but can't help thinking there must be an easier
way - any pointers?

Many Thanks
