RDN2008 / Zone 12 (E-N)

Italy - onshore and offshore. , accuracy 1.0 m, code 6711 (default) [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Approximation at the +/- 1m level assuming that ETRS89 is equivalent to WGS 84. RDN2008 is a regional realisation of ETRS89.
