DP1312.The coordinates were established by GPS observations
DP1312.and adjusted by the National Geodetic Survey in June 2019.
DP1312
DP1312.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP1312.been affixed to the stable North American Tectonic Plate.
DP1312
DP1312.The coordinates are valid at the epoch date displayed above
DP1312.which is a decimal equivalence of Year/Month/Day.
DP1312
DP1312.Due to the release of the International GNSS Service (IGS) 2014
DP1312.realization of the International Terrestrial Reference Frame of 2014
DP1312.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP1312.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP1312.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP1312.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP1312.currently published epoch of 2010.00.
DP1312
DP1312.Additional information on MYCS2 is available at
DP1312.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP1312.Significant digits in the geoid height do not necessarily reflect accuracy.
DP1312.GEOID18 height accuracy estimate available here.

DP1312.Click photographs - Photos may exist for this station.
DP1312
DP1312.The XYZ, and position/ellipsoidal ht. are equivalent.
DP1312
DP1312.The ellipsoidal height was determined by GPS observations
DP1312.and is referenced to NAD 83.
