Hey Thank you that worked. I have another question. I'm using google maps v3, when I used OpenLayers.Layer.Google with a Hybrid layer there were parts of the country (like Oakland california) where when I zoomed at the lowest level Google would automatically switch to Arial imagery.
When I use OpenLayers.Layer.GoogleNG (without switching the google API js link) this does not occur (google returns tiles in standard Hybrid top down view). Do you know if OpenLayers is doing something special to cause this behavrior? thanks Alessandro Ferrucci On Sun, Jul 24, 2011 at 5:00 PM, Andreas Hocevar <[email protected]> wrote: > If you're using OpenLayers trunk from svn, you can use > OpenLayers.Layer.GoogleNG instead of OpenLayers.Layer.Google.
