Hi Robert,
did you try proj.4 syntax? Like
"+proj=tmerc +lat_0=0 +lon_0=27 +k=1 +x_0=3500000 +y_0=0
+towgs84=-75,-230,-89 +ellps=intl"
This seems to work in my case.
Regards,

Hi!
I'm trying to do a conversion from Finnish KKJ coordinates to WGS 84
lat/long coordinates using PHP/MapScript. My problem is that I can't
figure out how to specify the transformation parameters.
The projection I'm trying to do looks like this:
$projIn =
ms_newProjectionObj("proj=tmerc,lat_0=0,lon_0=27,k=1,x_0=3500000,y_0=0,towgs84=-75,-230,-89,ellps=intl");
$projOut = ms_newProjectionObj("proj=latlong,datum=WGS84");
However the "towgs84=-75,-230,-89" part only works for the dx part
(-75) as MapScript apparently thinks -230 and -89 are new parameters.
I've tried different ways to specify the transformation parameters,
without any luck. Could someone help me out here?
Thanks in advance,
Robert Albrecht
