DO7623.The coordinates were established by GPS observations
DO7623.and adjusted by the National Geodetic Survey in June 2019.
DO7623
DO7623.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO7623.been affixed to the stable North American Tectonic Plate.
DO7623
DO7623.The coordinates are valid at the epoch date displayed above
DO7623.which is a decimal equivalence of Year/Month/Day.
DO7623
DO7623.Due to the release of the International GNSS Service (IGS) 2014
DO7623.realization of the International Terrestrial Reference Frame of 2014
DO7623.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO7623.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO7623.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO7623.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO7623.currently published epoch of 2010.00.
DO7623
DO7623.Additional information on MYCS2 is available at
DO7623.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DO7623
DO7623.The orthometric height was determined by GPS observations and a
DO7623.high-resolution geoid model using precise GPS observation and
DO7623.processing techniques.
DO7623
DO7623.Significant digits in the geoid height do not necessarily reflect accuracy.
DO7623.GEOID18 height accuracy estimate available here.
DO7623
DO7623.The PID for the CORS L1 Phase Center is DO7624.

DO7623.Click photographs - Photos may exist for this station.
DO7623
DO7623.The XYZ, and position/ellipsoidal ht. are equivalent.
DO7623
DO7623.The ellipsoidal height was determined by GPS observations
DO7623.and is referenced to NAD 83.
