Over the past decade I have wasted thousands and thousands of hours worrying about the reference and time dependent frame differences between realizations of NAD83 and current EPOCH WGS84.
Well, the Supreme Court of the United States (SCOTUS) made my life much easier on December 15th! No longer will I need to screw around with NGS’s HTDP program. No need to carefully consider the realizations of WGS84. In the ending paragraphs of the “UNITED STATES OF AMERICA, PLAINTIFF v. STATE OF CALIFORNIA” we find this gem:
“Plane coordinates refer to the Universal Transverse Mercator (UTM). All coordinates are referenced to the North American Datum 1983 (NAD83), which is equivalent to the World Geodetic System 1984 (WGS 84).”
If anyone else had made this proclamation I would have just brushed it off as the ramblings of a complete idiot. But considering the source, and the huge time savings I am going to enjoy, I gladly accept this statement by the highest court in our great land as the gospel truth.
Praise the Supreme Court! Hallelujah! If only all of our geodetic conundrums were so easily solved.
