[Paraview] How to intersect two datasets with ParaView

[Stefan Mauerberger]

Hello there! 

I wonder how to get the intersection two datasets in ParaView? 

What I have are:
 * A dataset covering the worlds coastlines
(http://www.earthmodels.org/data-and-tools/coastlines)
 * And the actual dataset, a 3d spherical section of the Earth (central
Europa to a 1000km depth) as a structured curvilinear grid in the NetCDF
file format
What I want to do is to cut out coastlines to the extends of the
spherical section. I just want to have coastlines at that region which
is covered by the spherical section (the rest of the Earth's coastlines
I want to leave out). 
Is there a way to achieve that with ParaView? 

Thanks for your help! 
Cheers, 
Stefan
