comment Why does this Mapserver layer not overlay correctly onto Google Maps?
Hi, I tried substituting the nadgrids line with the towgs84 line above, however this also makes no difference. I don't know if i am missing something fundamental here, but I have to think that the output format is incorrect for both of these layers to project incorrectly, yet i am using the "official" 900913 WKT for the output projection in my map file. If the problem was just the raster layer then i would suspect the WKT for that layer, but since the graticule layer has the same problem, it appears the issue must be the output WKT. Am I right or am i completely off target?

Hi, i tried this, but when i set the EPSG to 900913 in the WMS request using the same bounding box i get no overlay and all lat and lon labels return as 0's. When i change the bounding box in the request to -20037508.34, -20037508.34, 20037508.34, 20037508.34, i get the following image: link. My understanding of the request is that the EPSG defines the structure of the bounding box provided so the map server can render correctly, perhaps i have an incorrect bounding box when using 900913? Thanks for your help.
