projection
if I load shapefile MonteMario (EPSG 3003) with
parameters:
+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
the error is 70 meters
if I load shapefile with
SR personalized with the same parameters:
+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
