No, you don't have to display *every* contributor of the zone you are about to 
use. Quote from the CC-by-sa 2.0 license (the one OSM uses), emphasis mine:


4.c. If you distribute, publicly display, publicly perform, or publicly 
digitally perform the Work or any Derivative Works or Collective Works, You 
must keep intact all copyright notices for the Work and give the Original 
Author credit REASONABLE TO THE MEDIUM OR MEANS YOU ARE UTILIZING by 
conveying the name (or pseudonym if applicable) of the Original Author if 
supplied; 

Translated into plain english: if you can't *reasonably* write 800 names in 
your map, you don't need to. Just display the OSM logo, the CC license logo 
(and URL of the license if possible), and everyone will be happy.

(If you were writing a 2000-page enciclopaedia, then you should have enough 
spare space for writing down 1000 names of OSM contributors - but this is not 
your case)

The problem, IMHO, would be creating a derivative work that mixes 
Google-licensed data with CC-licensed data - section 4.a of CC-by-sa doesn't 
allow you to stick any other license to a derivative work.

Another problem is that the words "derivative work" are clear in a musical or 
literary environment, but not very clear in a GIS environment.
Does *just* overimposing a set of data over another set of data a derivative 
work, or is it a *collective* work?

I think we can suppose that your final product is a collective work, not a 
derivative work. In that case, just be clear about what parts are OSM (GIS 
data), what parts are google's (imaginery), and all is clear.





Disclaimer: I am not a lawyer. However, I'm friends with laywers that helped 
to translate CC licenses, so I'm quite familiar with all this legal 
mumbo-jumbo. But don't ever consider my opinion as final. I am not a lawyer.

I'll be forwarding this to my local CC mailing list, see what do the lawyers 
think.
