I'm trying to do something similar with Digital Chart of the World, which is
in VPF format (binary not ASCII). The biggest problem that I've come across is
that some of the edges (lines) are > 8K, so I'll have to store them as blobs
rather than in tuples as arrays. I'm still learning about blobs...
