CC-BY is attribution, CC-BY-SA is Attribution with Share Alike.

While geodata might not be, the meta data should be imho, but I'm not
a lawyer nor profess to be, and it would take legal action to actually
settle it one way or the other and that is on a per jurisdiction
basis.

ODBL is trying to add extra legal layers to CC-BY-SA by not relying on
just copyright to enforce the SA part.
