Topographic mapping (small scale).
Used by public and private agencies that need a single projected CRS for all Italian territory. See RDN2008 / Italy zone (E-N) (CRS code 7794) for similar CRS with east-north axis order used for GIS purposes.
Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
