Hi Chris, I don't think there's any tutorial existing, however the Google components that exist have a scenario. Drag and Drop one of these components to your job designer, and press F1 to access the component description. You will have a small scenario here that could help you.
Oh my bad, these components are only available in our Data Quality Enterprise Edition. However, I believe there's a tGoogleMapLookup (not sure about the name) component available in Talend Exchange. http://talendforge.org/exchange/index.php Just search for Google.
