As many readers know, the horizontal control stations in the NAD 83 system were readjusted and the results published in February 2007. It’s a national readjustment; all readjustment stations are in the same coordinate system.
The official name of the NAD 83 re-adjustment is "NAD 83(NSRS2007)." In order to minimize impacts on computer programs, which rely on the existing format of NGS datasheets, the "datum tag" on datasheets was shortened to "NAD 83(2007)" with an explanatory statement that this datum tag is a shorthand notation for "NAD 83(NSRS2007)." The use of "NAD 83(2007)" is solely a formatting issue on datasheets and should not be used as an official name for the re-adjustment of NAD 83.
