[Qgis-user] using EPSG:1662 transformation

[Michele Beneventi]

Hi all,
I'm using Qgis 1.6 release on windows xp pro 64-bit and in particulary
"export to new projection" (ftools).

I need to reprojct a layer from WGS84 / UTM zone 32N (EPSG:32632) to
Monte Mario / Italy zone 1 (EPSG:3003) with  the transformation 1662
(EPSG code).
I try to insert the value of the transformation in "custom CRS" with
proj4 syntax (+proj=tmerc +lat_0=0.0 +lon_0=9.0 +k=0.9996
+x_0=1500000.0 +y_0=0.0 +ellps=intl +units=m
+towgs84=-168.6,-34,38.6,-0.374,-0.679,-1.379,-9.48 +units=m +no_defs)
and create a new CRS target, but it seems doesn't work properly..

With gdalwarp I can put this value in the "-t_srs" parameter and run
the command with execellent results.

There is another way to customize the reprojection tool with the value
of local parameters?

Thanks in advance
regards

Michele
