DO2877.The coordinates were established by GPS observations
DO2877.and adjusted by the National Geodetic Survey in May 2021.
DO2877
DO2877.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO2877.been affixed to the stable North American Tectonic Plate.
DO2877
DO2877.The coordinates are valid at the epoch date displayed above
DO2877.which is a decimal equivalence of Year/Month/Day.
DO2877
DO2877.Due to the release of the International GNSS Service (IGS) 2014
DO2877.realization of the International Terrestrial Reference Frame of 2014
DO2877.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO2877.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO2877.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO2877.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO2877.currently published epoch of 2010.00.
DO2877
DO2877.Additional information on MYCS2 is available at
DO2877.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DO2877
DO2877.The orthometric height was determined by GPS observations and a
DO2877.high-resolution geoid model using precise GPS observation and
DO2877.processing techniques.
DO2877
DO2877.Significant digits in the geoid height do not necessarily reflect accuracy.
DO2877.GEOID18 height accuracy estimate available here.
DO2877
DO2877.The PID for the CORS L1 Phase Center is DQ6497.

DO2877.Click photographs - Photos may exist for this station.
DO2877
DO2877.The XYZ, and position/ellipsoidal ht. are equivalent.
DO2877
DO2877.The ellipsoidal height was determined by GPS observations
DO2877.and is referenced to NAD 83.
