EPSG:7809

ITRF2008 to NAD83(MA11) (1)

Attributes

Geodetic CRS: ITRF2008

Datum: International Terrestrial Reference Frame 2008

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Chris Pearson and Richard Snay, "Introducing HTDP 3.1 to transform coordinates across time and spatial reference frames", National Geodetic Survey (NGS), in GPS Solutions 28 February 2012.

Revision date: 2019-09-17

Scope: Geodesy.

Remarks: Information source gives IGS08 as source CRS: for most practical purposes IGS08 is equivalent to ITRF2008.

Method: Time-dependent Coordinate Frame rotation (geocen)

Area of use: Guam, Northern Mariana Islands and Palau; onshore and offshore.
