UTM Projection

[Dirk Jesko]

Hi,

if you specify the projection within the map file explicitly (not by 
epsg code) as Transverse Mercator ("proj=tmerc") and set the false 
easting (x_0 parameter) to 32500000 (?) it should work. Something like 
this probably

    PROJECTION
        "proj=tmerc"
        "lon_0=9.0"
        "x_0=32500000" # maybe something else
        "lat_0=0"
        "y_0=0"
        "ellps=wgs84"
        "datum=wgs84"
        "units=m"
        "k_0=0.9996"
        "no_defs"
    END

Let me know, if works.

The other option would be to rewrite the GeoTIFF-Header using geotifcp.

Dirk Jesko
