Getting Long/Lat From Physical Address

Just as the title says, I have a field that is the complete physical address of locations. Is there a way to lookup long/lat for each address so that I can map these events to a visual in Kibana?

Google maps has an API for that.

I don't understand, I would use ruby to make the API call and then store the returned long/lat in a separate field or is there a way to make a Kibana visualization (Not the Maps app) use Google's API?

You'd have to use something like a http filter that takes the address and calls the google api to get the coordinates.
