Hi Ian,
yes, GeoFence can clip data sources based on a target polygon, including
raster data (well just recently even
vector data, at the clipping level).

Takes a bit to get used to, it helps if you wrote IPTables rules in the
past, as the logic of rule application is similar
(recommend to read it carefully before trying to set them up)

Cheers
Andrea
