DO1809.The coordinates were established by GPS observations
DO1809.and adjusted by the National Geodetic Survey in February 2020.
DO1809
DO1809.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO1809.been affixed to the stable North American Tectonic Plate.
DO1809
DO1809.The coordinates are valid at the epoch date displayed above
DO1809.which is a decimal equivalence of Year/Month/Day.
DO1809
DO1809.Due to the release of the International GNSS Service (IGS) 2014
DO1809.realization of the International Terrestrial Reference Frame of 2014
DO1809.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO1809.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO1809.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO1809.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO1809.currently published epoch of 2010.00.
DO1809
DO1809.Additional information on MYCS2 is available at
DO1809.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO1809.Significant digits in the geoid height do not necessarily reflect accuracy.

DO1809.Click photographs - Photos may exist for this station.
DO1809
DO1809.The XYZ, and position/ellipsoidal ht. are equivalent.
DO1809
DO1809.The ellipsoidal height was determined by GPS observations
DO1809.and is referenced to NAD 83.
