DP1961.The coordinates were established by GPS observations
DP1961.and adjusted by the National Geodetic Survey in May 2020.
DP1961
DP1961.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP1961.been affixed to the stable North American Tectonic Plate.
DP1961
DP1961.The coordinates are valid at the epoch date displayed above
DP1961.which is a decimal equivalence of Year/Month/Day.
DP1961
DP1961.Due to the release of the International GNSS Service (IGS) 2014
DP1961.realization of the International Terrestrial Reference Frame of 2014
DP1961.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP1961.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP1961.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP1961.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP1961.currently published epoch of 2010.00.
DP1961
DP1961.Additional information on MYCS2 is available at
DP1961.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP1961.Significant digits in the geoid height do not necessarily reflect accuracy.
DP1961.GEOID18 height accuracy estimate available here.

DP1961.Click photographs - Photos may exist for this station.
DP1961
DP1961.The XYZ, and position/ellipsoidal ht. are equivalent.
DP1961
DP1961.The ellipsoidal height was determined by GPS observations
DP1961.and is referenced to NAD 83.
