[FWTools] Mapserver, Global.map and The Swedish RT-90

[Ingimar Erlingsson]

Hello!

Having a Swedish shapefile describing the counties in Sweden.
My ogrinfo says the following:

**********************************************************
**********************************************************
C:\ms4w\Apache\suecia>ogrinfo -al -summary svelan_2002_general.shp
INFO: Open of `svelan_2002_general.shp'

**********************************************************

There is no information in the 'Layer SRS WKT'.

In the global map I did enter the Extent, taken from ogrinfo,  as in 
EXTENT 1198493 6114582 1884297 767079

Mapserver should be able to generate the swedish RT-90 on the fly, so I've heard,
if it is defined in the global.map.

In the global.map I did enter the following:

PROJECTION
     "proj=tmerc"
     "ellps=bessel"
     "towgs84:414.1055246174,41.3265500042,603.0582474221,0.8551163377,-2.1413174055,7.0227298286,0.0"
     "lat_0=0.0000000000"
     "lon_0=15.0000000000"
     "k_0=1.0000000000"
     "x_0=1500000.0000000000"
END
- where towgs84 should be on the same line  
"towgs84:414.1055246174,41.3265500042,603.0582474221,0.8551163377,-2.1413174055,7.0227298286,0.0"

And for the layer I entered:
PROJECTION
         "proj=latlong"
         "ellps=WGS84"
     END

Still Having problems with the extent, my browser says:
" loadMapInternal(): General error message. Given map extent is invalid. "

Could anyone help on this one ?

Best regards, Ingimar
