Google Projection (Google it)

The commonly described 'Google Projection'. The trick here is the nadgrids=@null. Much much much help to sharpgis for his help on figuring this out:<br /><br /> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs<br /> <br /> (The proj4 output here does not export the '+nadgrids=@null'.)
