DL3077.The coordinates were established by GPS observations
DL3077.and adjusted by the National Geodetic Survey in June 2019.
DL3077
DL3077.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3077.been affixed to the stable North American Tectonic Plate.
DL3077
DL3077.The coordinates are valid at the epoch date displayed above
DL3077.which is a decimal equivalence of Year/Month/Day.
DL3077
DL3077.Due to the release of the International GNSS Service (IGS) 2014
DL3077.realization of the International Terrestrial Reference Frame of 2014
DL3077.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3077.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3077.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3077.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3077.currently published epoch of 2010.00.
DL3077
DL3077.Additional information on MYCS2 is available at
DL3077.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3077.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3077.GEOID18 height accuracy estimate available here.

DL3077.Click photographs - Photos may exist for this station.
DL3077
DL3077.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3077
DL3077.The ellipsoidal height was determined by GPS observations
DL3077.and is referenced to NAD 83.
