[OpenLayers-Users] Help w/ WMS onto google spherical mercator

[Richard Duivenvoorde]

Another option is to add the parameters yourself to the epsg file
(see 
http://www.spatialreference.org/ref/user/popular-visualisation-crs-mercator/proj4/
for parameters).

E.g. on my ms4w install, in the file:
C:\ms4w\proj\nad\epsg
I added:
# SpericalMercator projection
<900913> +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 <>

Regards,
Richard Duivenvoorde

I think this will become(?? anybody an idea here why these definitions 
(from proj) are different?):
<3785> +proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=6378137 +b=6378137 
+towgs84=0,0,0,0,0,0,0 +units=m +no_defs  <>
