I have two layers with the following projections: Monte Mario IT1 UTM*
Anyhow, I followed the instructions (open the project, set the projection, select on the fly projection, load the layers but no way, the two layers does not match each other.
I could only obtain the result of picture 1 where in red are the transport flows, in blue the transport network.
The crs of the two layers are: red--> +proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=1500000 +y_0=0 +ellps=intl +towgs84=-104.1,-49.1,-9.9,0.971,-2.917,0.714,-11.68 +units=m +no_defs blue--> +proj=tmerc +lat_0=0 +lon_0=9 +k=0.9996 +x_0=500053 +y_0=-3999820 +ellps=intl +towgs84=-87,-98,-121,0,0,0,0 +units=m +no_defs
If I set one of the layer with the same crs as the other, the two networks becomes very far from each others (see picture 2)
Which do you think might be the problem? Thank you, Selini
