The Geodetic Reference Frame that i use as horizontal Datum is: ITRF 2008 epoch 2010.0Based in the Global Reference System of 1980 (GRS80), similar to the World Geodetic System of 1984 (WGS84). 

 

And the vertical Datum is: North American Vertical Datum of 1988 (NAVD88) as the vertical control Datum of ortometric height.
