The current geodetic model of the earth used in the US is the North American Datumoften called NAD The system is used to define horizontal co-ordinates of reference markers all over the US. Although created as a geocentric datum which originates at the center of the earth, more recent models of the earth have shown the origin to be 2.

Other tidal (Mean High Water(MHW)) and geodetic (North American Vertical Datum (NAVD 88)) datums may also be used for specific reasons. The time meridian (TM) is the reference meridian used to calculate time.

An epoch is a year tidal cycle used to calculate datums. The present National Tidal Datum Epoch (NTDE) is through For the vertical datum use the North American Vertical Datum (NAVD) of Subsequent data incorporated into the Project that did not originate in these accepted survey control datums may be adjusted to these accepted survey datums and used for the Project only if the integrity and accuracy of the survey data is not affected.

Essentially, this is identical to the GRS 80 datum except that the normalized form factor has been slightly rounded off in the former datum, but its effects are very minor and should not affect survey operations.
