It is ok, isn't it?

CC-BY-SA doesn't require you to publish the source. It's not like the 
GPL in that regard.

It could be argued that this seriously restricts the utility of the 
ShareAlike clause for geodata, of course. You would have to manually 
trace the geodata from the derived work (map or database). You'd lose 
accuracy, and some web interfaces might make the process very tiresome. 
(This echoes Schuyler's point from the other day about CC's 
unsuitability for geodata.)

LGPL _does_ require you to make the source available - another strike 
in its favour.

tho'...
