It's just like carving an elephant: start with a block of wood, and take
away everything that doesn't look like an elephant.

Although I'm not the epitome of an imagery whiz, I seem to recall that
even SPOT data gives you an awful lot of trouble finding classifications
that hold still for the kind of linear features you're looking for.
