How can I tell if my SSID is in Google database?

Question, as per submission title: How can I tell if my SSID is in Google database?

Answer, as per article: You can't.

So there is no tool that would say "At the moment I'm using this SSID to determine location"?

Yes, there doesn't seem to be.

How can I check if my SSID is in Google database? I've never seen SSID with _nomap in their name.
