Scope: Transformation of coordinates at 4m level of accuracy.
Remarks: May be taken as approximate transformation Monte Mario to WGS 84 - see code 1662. For more accurate transformations to explicit realizations of ETRS89 see Monte Mario to IGM95 (4) and Monte Mario to RDN2008 (5), CTs 9733 and 9734.
Method: Position Vector transformation (geog2D domain)
Area of use: Italy - Sardinia onshore.
