Actually that's a good point, with CC-BY-SA it's obvious where it came
from, public domain can take a lot of effort to prove it's public
domain.

It's data, not source code, however that wasn't my point, my point was
GPL requires you distribute the source code if you distribute
binaries, CC-BY-SA doesn't require any such thing, you can convert the
data into raster format and still not be required to distribute the
modified data, although it is encouraged.
