Hello Plato,

You can write a program that processes your data 10 slices at a time (a 
very manageable 720MB as long as you have enough RAM). You can then append 
these polygonal data sets together. If they are too big, then you can 
decimate each of them (while preserving the edges) then glue them together 
and decimate the final structure.
