I was thinking the same thing.  20 thousand buildings is not that many
to trace if you get into a good routine.  In fact, the original import
process described sounded like more work than just tracing them from
scratch.  Not sure if the import data has address info and whatnot, but
if it is not acceptable license wise then it doesn't matter anyway.
