There is an example for MgCreateSdfParams() in the
"buffer.(php|aspx|jsp)" file in the folder
C:\program
files\MapGuideOpenSource2.0\WebServerExtensions\www\mapviewer(php|net|java)
It also shows how to set the coordinate system.
If your data has the correct projection, MapGuide will convert it to fit
the map projection.
If that does not work, you have to manually convert the items, which is
not a trivial procedure.
