[Qgis-user] Re: using EPSG:1662 transformation

[Michele Beneventi]

hi all,
Update.
After severals test I couldn't reproject in a properly way my
shapefile from 32632 to 3003 with transformation 1662 and of course
with ftools.
Am I missing something?
How can I customize a reprojection with a specific transformation (in
ths case the 1662) with ftools??

best regards
Michele
