DL2078.The coordinates were established by GPS observations
DL2078.and adjusted by the National Geodetic Survey in June 2019.
DL2078
DL2078.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2078.been affixed to the stable North American Tectonic Plate.
DL2078
DL2078.The coordinates are valid at the epoch date displayed above
DL2078.which is a decimal equivalence of Year/Month/Day.
DL2078
DL2078.Due to the release of the International GNSS Service (IGS) 2014
DL2078.realization of the International Terrestrial Reference Frame of 2014
DL2078.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2078.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2078.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2078.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2078.currently published epoch of 2010.00.
DL2078
DL2078.Additional information on MYCS2 is available at
DL2078.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL2078.Significant digits in the geoid height do not necessarily reflect accuracy.
DL2078.GEOID18 height accuracy estimate available here.

DL2078.Click photographs - Photos may exist for this station.
DL2078
DL2078.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2078
DL2078.The ellipsoidal height was determined by GPS observations
DL2078.and is referenced to NAD 83.
DL2078
DL2078. The following values were computed from the NAD 83(2011) position.
