It looks like you are trying to re-project Google raster layers? I thought OpenLayers was only capable of re-projecting vector layers?
For example, the following article uses OpenLayers (& Proj4JS) to re-project KML and GeoRSS data (geographic coords, WGS84) to a number of different projections (Mollweide, Behrmann, etc): http://www.geowebguru.com/articles/209-how-to-create-an-online-map-with-a-non-mercator-projection-part-2 Richard Marsden Winwaed Software Technology LLC http://www.winwaed.com http://www.mapping-tools.com http://www.geowebguruc.om On Thu, Nov 19, 2009 at 12:12 PM, Dash <jim...@co.clackamas.or.us> wrote: > > Aloha Thursday folks, > > I am banging my head against the problem for the last several hours.
