OpenStreetMap in Google Maps (hiding google credits)
Presenting OpenStreetMap (tiles) within google maps API (v3).
This covers up the google icon and the google 'terms' link with a white strip at the
bottom, while giving the required credit to OpenStreetMap. That avoids confusion and
seems fair in terms of ownership of the map, however it means google gets no credit
Instead you might leave google credits in place, but
add OSM credits
