<DIV><SPAN class=227152812-03032009><FONT face=Arial color=#0000ff>However,
adding +towgs84 parameters do not have any effect on the Mapserver output.
I am sure that this certain epsg file is read, because commenting out the
<2393> line makes Mapserver to stop working with my mapfile. In
addition, I can make map to shift by editing +x_0 and +y_0 parameters. I
had even another try by skipping the whole epsg file by giving the
projection directly in the layer definitions of my mapfile as

<DIV><SPAN class=227152812-03032009><FONT face=Arial color=#0000ff>Here I can
see exactly the same behaviour. Editing other parameters, like lon_0, x_0
and y_0 are really changing the output, while editing towgs84 parameters or
leaving them out totally has no effect. It looks to me that towgs84
parameters are not read at all, or all the parameters are interpreted as
zeros. However, I can't believe that this error wouldn't have been
noticed by others so far. So I am just giving the parameters in a wrong
way?</FONT></SPAN></DIV>
